f68565a33f Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine. 2017-08-17 10:48:29 -04:00
Thomas Harte
4c15e46fd1 Performed the normative removal from public view of Vic-20 implementation details. Which were hefty. 2017-08-16 16:05:30 -04:00
Thomas Harte
75208b0762 Moves the Electron implementation behind a more opaque interface, in line with changes elsewhere. 2017-08-16 15:33:40 -04:00
Thomas Harte
de1c526789 Cut the amount disclosed by the Atari 2600 for public inspection down to the minimum, relocating implementation into the .cpp. 2017-08-16 14:52:40 -04:00
Thomas Harte
148591b7f2 Hid most of the Oric innards, and corrected a potential multi-thread access error emanating from the Mac side of the world. 2017-08-16 14:35:53 -04:00
Thomas Harte
3947347d88 Introduces active input handling for the AY and uses it in the CPC to give proper, active keyboard input, rather than push-on-select, which was only ever a temporary hack. Also maps a few more keys for the Amstrad. 2017-08-15 22:47:17 -04:00
Thomas Harte
ad8c8166bc Built in gamma conversion for all machines, assuming an output of 2.8 for PAL, 2.2 for NTSC. 2017-08-10 15:17:08 -04:00
Thomas Harte
681d1e2f8d Breaking its typer for now, adapted the ZX80/81 to having a Z80, not being one. 2017-08-02 22:12:59 -04:00
Thomas Harte
9d43784c65 Significantly increased quantity of keys forwarded. 2017-08-01 20:37:55 -04:00
Thomas Harte
f5b278d683 Added enough stuff to put the emulated Amstrad CPC in a state of knowing whether its '0' key is pressed. 2017-08-01 17:31:56 -04:00
Thomas Harte
0536f089e1 Eliminated old-[personal-]fashioned line break. 2017-07-31 22:32:26 -04:00
Thomas Harte
3df13cddd4 As per my keenness for cleanliness improvements corresponding to my ever-increasing C++ ability: turned the Amstrad into something that a factory produces, allowing me completely to hide a bunch of implementation details. 2017-07-31 22:32:04 -04:00
Thomas Harte
afd409c883 Ensured that ROM images are loaded and passed to the Amstrad CPC. 2017-07-31 18:44:49 -04:00
Thomas Harte
c0f1313830 Performed sufficient wiring to get to the point where attempting to load a CDT creates an instance of the Amstrad CPC and then fails only because the thing vends a nullptr CRT. 2017-07-30 22:05:29 -04:00
Thomas Harte
d25d7d7d40 Added the Amstrad CPC as a named target and declared support for its CDT file format. 2017-07-29 21:56:33 -04:00
Thomas Harte
2ff157cf7a Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that. 2017-07-22 22:17:29 -04:00
Thomas Harte
6633537fb8 Discovering that there is such a thing as P81 — a ZX81 file without the name omitted — added support for it. Extended FileHolder while I was here to retain the file name and be able to supply its extension, as my quick-fix test-the-last-character approach to o/p/80/81 discrimination stops working with p81 thrown into the mix and this feels like the correct factoring. 2017-07-22 16:02:25 -04:00
Thomas Harte
2b5d0877a8 Adjusted parameter name to match documentation. I think it's a carry-over from before I was passing the whole event along. 2017-07-21 21:27:50 -04:00
Thomas Harte
238348c885 Performed the initial wiring to announce that this application supports TZX files and to route them to the ZX80/81 static analyser. The TZX class itself does not yet do much beyond basic validation. I think it'll be easiest if it follows in UEF's footsteps in queuing up pulses ahead of time, so some factoring out is now required. 2017-07-16 21:33:11 -04:00
Thomas Harte
279f4760d7 Eliminated buffer_size_ as something explicitly stored, and reduced size of delegate call out. 2017-07-16 15:01:39 -04:00
Thomas Harte
368bff1a82 Added a shell class that will one day be able to parse CSW files, plus the logic and metadata to instantiate it when a CSW presents itself. 2017-07-10 21:43:58 -04:00
Thomas Harte
54efcb7e2f Made a game attempt at automatic motor control and ensured setting is initialised correctly from the user defaults. 2017-07-08 19:31:20 -04:00
Thomas Harte
e2575d6de4 Routed tape motor selections through to the C++ side of the world, and ensured that manual tape playback works properly. 2017-07-08 19:21:12 -04:00
Thomas Harte
23e989e170 This will likely do for the Swift/XIB side of things: the play/pause button is enabled or disabled as per the user's choice of automatic tape control, and toggles function when pressed. It communicates activity down to the Objective-C[++] layer, giving it a route through to the actual machine. 2017-07-08 19:12:06 -04:00
Thomas Harte
28412150e6 Added controls for controlling the tape motor of the ZX80/81, assuming I can find an automatic option. 2017-07-08 17:59:33 -04:00
Thomas Harte
644ef13acd Connected up the fast-tape GUI option for the ZX80 and '81. 2017-06-22 20:20:31 -04:00
Thomas Harte
a48616a138 Fixed reference to Swift-world MachineDocument for the ZX81 file type. 2017-06-12 18:51:11 -04:00
Thomas Harte
8222aac9e3 Added an official declaration of support for ZX81 files. 2017-06-11 21:40:41 -04:00
Thomas Harte
8116f85479 Allowed the static analyser to specify a ZX80 or 81, and a memory model. Neither is respected yet in the machine. 2017-06-11 19:12:20 -04:00
Thomas Harte
cc4cb45e9d Implemented keyboard input and ensured that the signal generated is marked as composite, putting the colour-suppression ball into the CRT's court. 2017-06-06 09:25:18 -04:00
Thomas Harte
c485c460f7 Imported the ZX80 and 81 system ROMs (though not publicly), added enough code to post their contents into C++ world. 2017-06-04 18:08:35 -04:00
Thomas Harte
b0a7c58287 Fixed project to point to the XIB I actually want to keep; fixed that XIB to have the correct contents. 2017-06-04 17:57:37 -04:00
Thomas Harte
d2637123c4 Added necessary support to get as far as an empty window when attempting to load a piece of ZX80 software. 2017-06-04 17:55:19 -04:00
Thomas Harte
655809517c Ensured that there is a subclass of file that is entrusted to load .O/.80 files, and that the code routes such files to it, noting that it should consider whether a ZX80 is required. 2017-06-04 16:37:03 -04:00
Thomas Harte
9398b6c2c8 Unable to differentiate, decided to map a Mac shift key to both Oric shifts. 2017-05-18 22:25:59 -04:00
Thomas Harte
8e35e913bb Formally withdrew the 'load automatically' option for the Vic, having removed that option elsewhere. 2017-05-14 16:59:24 -04:00
Thomas Harte
2edf73908c Temporarily disabled the existing fast loading implementation in pursuit of another, and started trying to correct the lack of connection between the userport VIA and the tape drive. 2017-05-06 22:00:12 -04:00
Thomas Harte
92a8b68859 Dumped Mach-specific test-and-set in favour of ordinary C11. 2017-04-15 21:41:59 -04:00
Thomas Harte
bdd432fe1d Added an ugly workaround for the empirical sound shutdown issues. 2017-03-26 20:28:04 -04:00
Thomas Harte
b193248056 Ensured that queue is not touched at all outside of the critical section. 2017-03-11 18:17:09 -05:00
Thomas Harte
38ce4dc56c Fixed potential deadlock, if a delegate decided to dealloc the queue as a result of its prompting. 2017-03-11 17:44:02 -05:00
Thomas Harte
dcd0c90283 Switched time of best-effort updater delegate setting, to avoid a callback before setupClockRate has happened, and therefore before it's clear what should be going on with audio. 2017-02-26 21:58:59 -05:00
Thomas Harte
2f0c923c29 Switched away from @synchronized as it appears possibly to be the lock used during -dealloc, creating deadlock with the CSAudioQueueDeallocLock. 2017-02-22 21:42:10 -05:00
Thomas Harte
4c947ad553 Attempted to resolve risk of an audio callback being in progress when -dealloc is received. 2017-02-22 21:12:59 -05:00
Thomas Harte
1d03793f22 Fixed potential race condition: ensure the queue is disposed of synchronously because otherwise there'll be a potential dangling reference to self. 2017-02-22 07:35:09 -05:00
Thomas Harte
99a35266e1 Attempted to bring frequency-switching logic into the cross-platform realm. Which for now creates an issue with the OpenGL context. 2017-02-19 21:20:37 -05:00
Thomas Harte
327c19a222 Slightly shuffled to avoid a race condition on the best-effort updater. 2017-02-11 12:58:47 -05:00
Thomas Harte
fba6baaa9c Stubbed and disabled to get back to building. 2017-01-28 21:56:01 -05:00
Thomas Harte
9001cc3fc2 Added a cartridge image. 2017-01-27 21:26:11 -05:00
Thomas Harte
015b2b49f9 Introduced an incomplete set of file association icons. 2017-01-26 22:21:55 -05:00
Thomas Harte
580f347727 Fixed Oric SCART mode by having it change what it's giving to the CRT based on which shader it knows will be active. 2016-12-10 13:55:56 -05:00
Thomas Harte
6cdd41e5a9 Added direct use of the colour ROM, uploading 16 bits per pixel to contain the entire ROM composite wave. 2016-12-09 22:17:10 -05:00
Thomas Harte
ea33a28695 Any Oric-format disks that are inserted now make it all the way to the Oric, along with a request to emulate the Microdisc. It has received a copy of the ROM. The ball is entirely in its court now. 2016-11-21 20:59:25 +08:00
Thomas Harte
8499783b14 Dragged multibyte primitives and signature checks up to the base class. Implemented support for Oric MFM-style .DSK, at the file format level. 2016-11-21 20:47:16 +08:00
Thomas Harte
e2cdfae8a7 The emulated Oric now has access to both versions of the BASIC ROM and picks between them based on the static analyser's recommendation. 2016-11-15 10:39:16 +08:00
Thomas Harte
a2e5fd2a1f Corrected layout error. 2016-11-03 08:02:13 -04:00
Thomas Harte
9c2df231ce Made fast loading optional. 2016-11-03 07:59:30 -04:00
Thomas Harte
e5fe37f089 Fixed 'joystick' input. 2016-10-27 19:44:48 -04:00
Thomas Harte
5c23acdbaf Switched window style back for the Atari HUD. 2016-10-27 19:40:29 -04:00
Thomas Harte
013f0c5317 Finally forced emulation window to front. Also removed min/max heights where they'd crept in and got explicit about the OpenGL view being first responder. 2016-10-24 22:08:24 -04:00
Thomas Harte
91831b6a95 Introduced a reuse list for audio buffers, based on the observation that the audio queue seems to start quick rejecting them. 2016-10-23 21:17:00 -04:00
Thomas Harte
7c33c34b0c Have withdrawn attempt to be clever with client notification here, as it was having no effect in the current environment, making it hard to build up any confidence. 2016-10-23 20:33:59 -04:00
Thomas Harte
f13d7ed6f4 Added an extra safety rail. 2016-10-20 07:36:53 -04:00
Thomas Harte
73365e1877 Resolved sizing error. 2016-10-19 23:09:05 -04:00
Thomas Harte
c24c1bf3b1 Created an options panel for the Oric. Which involved far too much copy and paste from the Electron. Time to figure out how to generalise this stuff, probably. 2016-10-19 22:56:14 -04:00
Thomas Harte
5a808d789a Added an upper threshold that must be crossed before a lower threshold warning is communicated. 2016-10-18 22:21:34 -04:00
Thomas Harte
f6b6ec7009 Cemented new meaningof the audio queue delegate callout. 2016-10-17 08:18:32 -04:00
Thomas Harte
c105f2acd9 Sought to reduce chattiness. 2016-10-17 08:04:36 -04:00
Thomas Harte
b274d7008c Added precaution to make sure best-effort updaters aren't mid-update during document destruction. 2016-10-16 22:14:47 -04:00
Thomas Harte
da9c9ad51a Added in the missing keys; added variable phase to the video. 2016-10-14 22:39:27 -04:00
Thomas Harte
138eabcff4 Continued in my effort to wire up a keyboard. Will need further to continue. 2016-10-14 21:35:15 -04:00
Thomas Harte
d8e4c488c2 Started iterating towards having an AY and a fully-working keyboard. 2016-10-14 21:18:03 -04:00
Thomas Harte
0ca383ecd1 Set every single key to be NMI, in order to be able to progress with the diagnostics cartridge. 2016-10-13 18:56:55 -04:00
Thomas Harte
120b2d9e33 Switched to using a diagnostic ROM for now, as it'll definitely boot without initially requiring either a 6522 or AY. Have some forms appearing which imply I'm not doing badly, at least up to not knowing where I'm supposed to get character pixels from. 2016-10-12 21:52:47 -04:00
Thomas Harte
e6937d8003 Ensured that the ROM gets installed. So next for some video action? 2016-10-12 18:51:02 -04:00
Thomas Harte
4a062c616f Added enough wiring to get Oric TAPs through to a completely unimplemented Oric emulation. 2016-10-11 22:20:13 -04:00
Thomas Harte
cbc3d28217 Ensured an exception is thrown if no machine to run a file is found. E.g. right now if you tried to open a ZX Spectrum .tap. 2016-10-11 21:03:01 -04:00
Thomas Harte
df01c78039 It's a bit of a mess but this is probably close to appropriate for Oric TAP files. 2016-10-11 07:39:48 -04:00
Thomas Harte
02bfa8b8de This should just trust. 2016-10-10 07:45:09 -04:00
Thomas Harte
f4b39c4435 Added documentation and experimentally reduced packet size. We'll see. 2016-10-10 07:42:24 -04:00
Thomas Harte
de397799ed Pulled away my crazy rationalisation of an audio queue into a circular buffer and decided just to trust the OS. This should reduce latency. 2016-10-10 07:30:00 -04:00
Thomas Harte
fa7c64bb5d Eventually reached an implementation of ADC that continues to satisfy all the formalised unit tests while also satisfying the manual BCDTest, that I need to find a way to formalise. I fixed the unit tests for Swift 3 while here, and attempted to do some unrelated NIB stuff with no real success. 2016-10-03 22:03:39 -04:00
Thomas Harte
cfdd5fb686 By removing its status as a special case, eliminated the Atari 2600 document. It's fairly clear that my date with doing joysticks properly can be deferred only so much longer but this is no worse than previously things were. 2016-10-03 08:01:04 -04:00
Thomas Harte
bf468db73d Migrated the Vic document to a mere options panel. 2016-10-03 07:42:05 -04:00
Thomas Harte
9e6e84647e Quick formatting fix. 2016-10-02 22:06:28 -04:00
Thomas Harte
f28881ec6b ... and with the return of stored options and the shift of the aspect ratio to somewhere else (to sit, temporarily), the Electron document is the first of the gang to die. 2016-10-02 22:04:47 -04:00
Thomas Harte
19457621d8 Redistributed ownership of the user defaults key prefix, the Electron now works other than that settings aren't retained. 2016-10-02 21:56:50 -04:00
Thomas Harte
f1b99263e0 Relocated responsibility for loading ROMs, giving an Electron that 'works' (i.e. options aside) again. 2016-10-02 20:39:06 -04:00
Thomas Harte
989a1581da Migrated analysis logic from the document controller to the document. 2016-10-02 17:04:14 -04:00
Thomas Harte
0c75c2fc41 Disabled all machine-specific document code, to force the migration of functionality. The 2600 works other than the little matter of input. 2016-10-02 16:57:57 -04:00
Thomas Harte
6c6e9830dd Started factoring the options panels out, in the hope that they'll become the only machine-specific thing. At least in the short term. 2016-10-02 16:31:50 -04:00
Thomas Harte
ce4100e5b9 Fixed slots for DFS and ADFS to sideways RAM; continued working on the 1770 to get as far as trying to get the body of a sector. 2016-09-24 22:04:54 -04:00
Thomas Harte
cd5939501f Treading water some more, ensured the DFS and ADFS ROMs get to the Electron. It now even inserts the DFS ROM if it has a DFS disk image. Might need to make it a sideways RAM though? Regardless, the next job surely — surely! — has to be to stop avoiding the 1770? 2016-09-20 07:36:57 -04:00
Thomas Harte
c9dd07cecd DFS disks are now delivered right up to the emulator's front door. So everything's in place to get started on that WD1770 nonsense. 2016-09-19 08:29:23 -04:00
Thomas Harte
fbcb59d47a A policy change trial: let the person above deal with any error. 2016-09-18 21:18:41 -04:00
Thomas Harte
bcf91de7e9 Declared support for the Acorn disk files, started hammering out an encoder. 2016-09-18 13:35:54 -04:00
Thomas Harte
a98374995e Cleaned up pre-analysis code. 2016-09-17 18:19:32 -04:00
Thomas Harte
7c65c69e0f Migrated to Swift 3. 2016-09-15 22:12:12 -04:00
Thomas Harte
ee8510984f Added just enough wiring to restore the 2600 to functionality. 2016-09-15 19:34:45 -04:00
Thomas Harte
c3a795328d Windows have titles again. Also I've owned up to not knowing how to edit UEFs right now. 2016-09-12 22:15:38 -04:00
Thomas Harte
40660fe680 Made yet another guess at Commodore analysis. Elevated fast tape-related unnatural speed up to the OS-side mechanisms. 2016-09-12 22:06:03 -04:00
Thomas Harte
908dc40569 If loading automatically, assume that whatever was in the machine target set up the machine and don't override it. Too dodgy? More thought required. 2016-09-08 07:38:34 -04:00
Thomas Harte
8c84f3581a Attempted to bring some uniformity in application of configurations. 2016-09-08 05:32:17 -04:00
Thomas Harte
50175a9aed Added logic to try to spot when the first program is BASIC and, if so, what the correct memory model is, then to get that information to the Vic. Though it currently then gets overwritten by the view controller. Grrrr. 2016-09-07 22:17:19 -04:00
Thomas Harte
21e5f407d8 I need to get a bit more definitive on naming but this gets all the way to setting a configuration upon an Electron. 2016-08-31 22:03:42 -04:00
Thomas Harte
a9b67dfba0 Introduced an NSDocumentController subclass. 2016-08-31 21:21:07 -04:00
Thomas Harte
7bc2b6b161 Added the minor piece that will allow analysis results to be obtained from Objective-C, and exposed to Swift in sufficient detail for it to be able to pass on to the machine. 2016-08-31 20:43:29 -04:00
Thomas Harte
d1abfc040c Addressed my dithering here: the file format containers themselves should do nothing but inspect the data to find out whether it is of the correct format. The machine steps are there for machine-specific validation. So it's probably easier to treat a binary ROM image just as a binary ROM image. Therefore, the Acorn-specific .rom detection is now in an Acorn-specific area. 2016-08-29 08:48:49 -04:00
Thomas Harte
29c972f4b8 Added hacky segue into analysis for all Electron formats. Added analyser to try to differentiate Acorn-format ROMs from other things called .rom, which are likely to be numerous. 2016-08-28 12:43:17 -04:00
Thomas Harte
56c0d70c1f Gave disks their own namespace. 2016-08-27 17:15:09 -04:00
Thomas Harte
c0402d0c2b Gave tapes their own namespace. 2016-08-27 17:09:45 -04:00
Thomas Harte
8c333059a8 Turning this into a slog: gave UEF a more appropriate name, got as far as now having to decide what to do about ROMs as to structure. I guess they're machine specific, so specific classes? 2016-08-27 16:40:21 -04:00
Thomas Harte
0d077691b0 Resolved warning. 2016-08-23 21:10:22 -04:00
Thomas Harte
38aec44d85 Made sufficient changes for the Vic itself to believe it can recast a PRG as a tape and insert it that way. So now the ball is in the court of: how the heck are Commodore tapes encoded? 2016-08-15 19:44:41 -04:00
Thomas Harte
6079d30e58 Eliminated waiting here — either the buffer can be enqueued now or it is dropped. 2016-08-14 16:20:24 -04:00
Thomas Harte
5373f6cc57 Completed setting of options, including mapping from country to ROM + television standard. 2016-08-14 14:23:08 -04:00
Thomas Harte
b5af1746d5 Added a through path to the Objective-C for setting region and memory size. 2016-08-14 14:14:59 -04:00
Thomas Harte
f15d89239f Made a stab at storage and restoration of country and memory size. 2016-08-14 14:00:08 -04:00
Thomas Harte
df77c2a20a Added the XIB side of wiring for region and memory size options. 2016-08-14 13:53:14 -04:00
Thomas Harte
12bad8f23f Turned the 6560 into an ordinary template, similar to the rest of the project, albeit right now with a fairly shonky internal implementation. Fixed a Mac-specific interface sizing issue. 2016-08-09 20:41:05 -04:00
Thomas Harte
285a288c80 Switched to two cycles of options loading, meaning that they get set before files are inserted. Might need some further work? 2016-08-07 21:48:09 -04:00
Thomas Harte
be54d8040e Made a first stab at having automatic loading be optional. But things are currently arranged such that the machine options are communicated too late to have an effect. So work to do. 2016-08-06 17:39:27 -04:00
Thomas Harte
58297f1baf Performed the basic metadata and routing for opening D64 files. Realised that I wasn't actually necessarily catching exceptions properly for all file opens, and fixed. 2016-08-01 07:09:15 -04:00
Thomas Harte
18744cd98b Slightly updated comments, switched to 1540 ROM so as very slightly to improve loading time. 2016-08-01 04:37:30 -04:00
Thomas Harte
6cfc514c2d Made the rote changes necessary to attempt to open and to supply a G64 to the Vic. 2016-07-10 12:57:17 -04:00
Thomas Harte
7cc4bf3fe7 Hit and hope is getting me nowhere. Time to unit test this thing. 2016-07-09 15:40:25 -04:00
Thomas Harte
81e6cc34e5 Per the ROM disassembly, the Vic's VIA outputs are inverted for the benefit of the serial bus. 2016-07-07 06:57:21 -04:00
Thomas Harte
1baf21827c Since the ROM is well disassembled, let's actually try to be a 1541 first. 2016-07-06 22:17:32 -04:00
Thomas Harte
d1eea6943d Ensured the 1540 ROM gets installed, at least. 2016-07-05 16:54:25 -04:00
Thomas Harte
47548dcedc Fixed an erroneous #import. 2016-07-05 16:39:31 -04:00
Thomas Harte
86dabd007b Furthered fleshing out of the 1540. Though it doesn't yet receive a ROM so won't even attempt to do anything meaningful. 2016-07-05 16:39:18 -04:00
Thomas Harte
0d3d0fbe4d Created a namespace for Commodore and an empty container file for the 1540[/1] implementation. 2016-07-05 13:28:27 -04:00
Thomas Harte
df4724eb3e Added a modal toggle allowing the keyboard to be switched between being a keyboard and being a joystick for the Vic. 2016-07-04 22:01:07 -04:00
Thomas Harte
88964ceac0 Eliminated plain pointer passing for object types. 2016-07-04 19:33:55 -04:00
Thomas Harte
6dbf16210b Switched protocol to meaningful name and corrected its omission from the repository. 2016-07-04 19:19:07 -04:00
Thomas Harte
6027cba95f Factored out the stuff of pushing a fast-loading option onwards and storing it within the user defaults. 2016-06-27 21:38:14 -04:00
Thomas Harte
9134e4de1f Added a partially-wired options menu for the VIC. 2016-06-27 18:49:53 -04:00
Thomas Harte
8741be5c84 Made the slightest possible effort to get TAPs opened and passed to the VIC. 2016-06-25 16:24:52 -04:00
Thomas Harte
ee19417ded Made an attempt quickly to implement parsing of the Commodore .TAP file format. 2016-06-25 16:09:32 -04:00
Thomas Harte
b8728285e7 An overridden getter looks more like this in Swift. 2016-06-23 21:09:34 -04:00
Thomas Harte
097a9caa95 Delegates are all nullable, naturally. 2016-06-23 09:37:49 -04:00
Thomas Harte
454e98302d Slight rearrangement plus a setting of the CSMachine delegate corrects audio after a clock rate change. 2016-06-20 22:18:41 -04:00
Thomas Harte
31b26b8118 Made a first attempt to implement the full top-to-bottom change of clock rates, giving the Atari the ability to change rate when it switches to PAL mode, as it should always have been. 2016-06-20 21:47:27 -04:00
Thomas Harte
3591479571 Fixed mismatch between initial tick box states and communicated switches; ensured they're visible upon launching a game. 2016-06-20 21:31:07 -04:00
Thomas Harte
6c3f5d2caf Fixed window sizing. 2016-06-19 21:40:35 -04:00
Thomas Harte
065ec618c4 Factored out and templated the 6532, finally taking the opportunity to add a means to control the on-console switches of an Atari 2600. 2016-06-19 19:36:34 -04:00
Thomas Harte
ef3ed1f436 Implemented full paste ability for any machine that is a typer. 2016-06-19 16:35:04 -04:00
Thomas Harte
090e92ad26 Making this large has very limited side effects. So why not? 2016-06-16 21:41:17 -04:00
Thomas Harte
3b71d1a309 Switched to a variable-length buffer based on attempting to hit approximately a certain quality of service. 2016-06-16 21:35:22 -04:00
Thomas Harte
2ee78d42b9 Made an attempt also to trigger updates upon audio packets being returned, and significantly to reduce the size and quantity of those. This should get down to 11ms latency if the output wave is 44100; I might need to scale up the buffer size as the sampling rate increases or this is going to get crazy at 192Khz. 2016-06-16 20:51:35 -04:00
Thomas Harte
00a9f1bf24 Fixed best-effort updater actually to run, finally moved clock rate announcement into the C++ side of things, started working on a mechanism to allow clock rate to be updated. 2016-06-16 20:39:46 -04:00
Thomas Harte
1921a6c469 Rewired the existing cause-an-update route from the OpenGLView through the best-effort updater. 2016-06-16 18:19:23 -04:00
Thomas Harte
530cf3dcbb Made an attempt to consolidate serialisation and clock rate adherence, allowing a floating-point clock rate. 2016-06-16 18:04:54 -04:00
Thomas Harte
ce59ad1911 Minor on-disk shuffle, to try to clarify ownership of responsibility. 2016-06-15 08:11:30 -04:00
Thomas Harte
45999f5b26 This should be strong. 2016-06-15 08:07:59 -04:00
Thomas Harte
e0baaf17f1 Added class prefix. 2016-06-15 08:07:25 -04:00
Thomas Harte
695dd2e9e3 Started upon a delegate protocol for the AudioQueue, resolving my use of a deprecated API while I'm at it. 2016-06-15 07:35:34 -04:00
Thomas Harte
a9036e7aa4 Increased buffering range of audio as a quick fix for now. Basically means: increased latency as a short-term fix. 2016-06-14 07:31:47 -04:00
Thomas Harte
fcf4b14344 Extended to allow floating-point sampling rates. Which makes sense. 2016-06-13 19:30:41 -04:00
Thomas Harte
4fec625b19 Minor cleaning, implemented clearAllKeys. 2016-06-12 10:38:21 -04:00
Thomas Harte
ec604f1414 Expanded mapped keys just a tiny bit further. 2016-06-12 10:35:47 -04:00
Thomas Harte
167ed9b8bb Added enough to load a PRG as a ROM. 2016-06-11 14:00:12 -04:00
Thomas Harte
d9b001d3fc Minor clean-ups. 2016-06-11 13:51:04 -04:00
Thomas Harte
3e8d383615 Improved key map. Possibly enough to type some basic BASIC? 2016-06-11 13:19:59 -04:00
Thomas Harte
d1731b1d26 Hacked my 6522 to work. Mistake is in not returning output as input when appropriate — i.e. that I'm ignoring data direction. Also fixed K and L keys. 2016-06-11 13:06:01 -04:00
Thomas Harte
271de23ee6 Ran on in and introduced a bunch more keys, hopefully to help to diagnose. 2016-06-11 12:26:19 -04:00
Thomas Harte
d7c1f5b18a Made an attempt at hooking up the '2' and '4' keys. A mostly unsuccessful attempt. 2 does nothing, 4 clears the screen. 2016-06-11 11:50:37 -04:00
Thomas Harte
0b221e773f Fixed ROM naming and sizes, ensured machines without sound outputs don't end up with an audio queue. 2016-06-05 11:20:05 -04:00
Thomas Harte
12243c40ad Kicking the ball a little further down the road, ROMs and PRGs now reach the actual emulated machine. 2016-06-05 09:06:59 -04:00
Thomas Harte
b29b2a5d08 Added forwarding of a loaded PRG from the Swift document to the wrapper. So I think that possibly completes the Swift side of things? 2016-06-05 09:01:32 -04:00
Thomas Harte
8052ce9223 System ROMs are now supplied to the Vic-20 wrapper, though they stop there. I also factored key forwarding out of the ElectronDocument and into the superclass, depending upon the child conforming to CSKeyboardMachine. 2016-06-05 08:53:05 -04:00
Thomas Harte
363e14a92f Reorganised system ROMs out of the Mac-specific folder, adjusted Mac code to expect to find them organised hierarchically (as how many os.roms am I going to have?) and added readme files to explain what's missing from the Git repository. 2016-06-05 08:33:01 -04:00
Thomas Harte
b10a06e700 A CRT is still absent but this moves the ball back into the C++ side's court. 2016-06-04 22:00:50 -04:00
Thomas Harte
06e1db8c85 This now gets as far as missing selectors. 2016-06-04 21:49:03 -04:00
Thomas Harte
eff28e95a4 Added XIB file. 2016-06-04 21:45:39 -04:00
Thomas Harte
404873fe58 Started sketching out infrastructure for Vic-20 support. 2016-06-04 21:43:50 -04:00
Thomas Harte
d6e8cd676a Trimmed and reordered just a little. 2016-06-04 16:02:16 -04:00
Thomas Harte
68a8851c52 Increased parallelism, allowing a simplification in the GL view. 2016-06-02 22:29:09 -04:00
Thomas Harte
e3b95b8d2b Back to asynchronous updates and drawing, to try to improve guarantees on audio latency; experimenting with whether other parts of the approach are fundamentally flawed; added a broad-phase for scheduled updates on the 2600. 2016-06-02 21:22:55 -04:00
Thomas Harte
11073daee1 Issues appear to be around timing generally. Working on it. 2016-06-02 20:15:48 -04:00
Thomas Harte
253e5a4203 With no regard to performance whatsoever, endeavoured to bring sound to the 2600. It's very scratchy, so something is wrong. 2016-06-02 19:50:16 -04:00
Thomas Harte
8623dc2833 Consolidated a little more within the common code, adding sampling rate selection based on querying the machine. 2016-06-01 19:04:07 -04:00
Thomas Harte
50543e9676 Minor factoring up: the audio queue is now pushed universally by MachineDocument. 2016-05-31 22:36:53 -04:00
Thomas Harte
c773c3a66c Started trying to clean up and consolidate on the Swift side of things but time is up for the day. 2016-05-31 22:32:38 -04:00
Thomas Harte
8dc66167be Made an attempt to consolidate the Objective-C++ side of things based on the incoming CRTMachine::Machine. 2016-05-31 22:16:20 -04:00
Thomas Harte
5c4f35e13f Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be. 2016-05-31 21:23:44 -04:00
Thomas Harte
40600b4bcb Made sprite placement consistent at least. Not necessarily yet correct. 2016-05-18 22:07:24 -04:00
Thomas Harte
3765c5fbb5 Fixed error that would prevent an interrupting frame from ever being drawn. 2016-05-18 21:45:35 -04:00
Thomas Harte
ddfc9910e5 Sought to draw in a standard serial arrangement as and when bandwidth allows it. 2016-05-09 07:17:12 -04:00
Thomas Harte
1bb92550f8 It's 2016. 2016-05-02 22:02:06 -04:00
Thomas Harte
6982e945fb Fixed those issues breaking GL state, I hope. 2016-05-01 16:17:52 -04:00
Thomas Harte
9b64f64db7 Attempted to normalise some style decisions.` 2016-04-24 22:32:24 -04:00
Thomas Harte
884755c560 Ensured the GL context is available when switching Atari 2600 output, and that it locks the output. 2016-04-24 20:56:21 -04:00
Thomas Harte
d221c712b0 Ensured GL context is active when destructing CRTOpenGL. 2016-04-24 20:34:25 -04:00
Thomas Harte
929cfc49cb Extended window for picking output frequency, attempted to consolidate CRT OpenGL timing uniforms for approprate resetting. 2016-04-24 18:58:31 -04:00
Thomas Harte
082003ed0a Reintroduced the CRT delegate and the 2600's automatic region switching. Albeit that the CRT itself doesn't adjust properly to new timings yet. 2016-04-24 18:36:22 -04:00
Thomas Harte
80a3169674 Started reviving the Atari 2600 emulation. Put new startup sequence into place. 2016-04-24 06:56:08 -04:00
Thomas Harte
9c89b668ae Made further attempts to improve synchronisation and interrelated timing between display and machine update. 2016-04-20 22:35:46 -04:00
Thomas Harte
7aa87723a9 Added: key states are all cleared if the window loses focus. Which resolves sticky key issues. Allowing me just to use command+option+O for options and map both command and option as FUNC. 2016-04-19 21:29:10 -04:00
Thomas Harte
d5bac2f04f Spotted error was in texture target all along. This now gets as far as showing something a lot like the correct display, but precision is way off. Way off. 2016-04-18 21:32:48 -04:00
