eeb0e134fd Started the transition towards a more natural collection of rolling buffers, with phosphor decay in mind. 2016-02-13 20:52:23 -05:00
Thomas Harte
a6574d1f96 Made an attempt to factor out and more clearly to document my implementation of flywheel synchronisation. 2016-02-11 22:12:12 -05:00

4d0a218a57 Certainly at least seriously considering a separate holder for the "compile a shader" logic. Otherwise taking steps back towards PAL/NTSC decoding. 2016-02-07 17:32:38 -05:00
Thomas Harte
602327cd9d Sketched out a quick class for rendering to texture. 2016-02-07 15:42:02 -05:00

e0d51408e4 Onward with carrying this through to the bitter end, this at least results in all the appropriate knowledge and call-ins occuring at the CRT. 2016-02-04 22:28:50 -05:00

5a39e42413 Wired up enough such that some basic attempt at parsing a UEF occurs.` 2016-01-18 17:06:09 -06:00
Thomas Harte
2779f0e569 Statred working on support for at least the most fundamental file format. 2016-01-18 15:46:41 -06:00

38ffcaa262 Here, at last, is _some_ audio output, at least. 2016-01-14 20:33:22 -05:00
Thomas Harte
84ba4e2900 Tidied a little, started working towards supporting speaker output. 2016-01-12 22:19:56 -05:00
Thomas Harte
3437781abd Started sketching out an interface for sound generation. Which made me realise that the CRT in CRTDelegate was redundant, since C++ has namespaces. 2016-01-12 16:54:09 -05:00

e93dbdb463 Implemented keyboard input. 2016-01-11 19:48:31 -05:00

0db8938d27 Added the option for the CSCathodeRayView to show only a subsection of the full scan area. Zoomed in a little on the 2600. Put in enough piping to give the Electron sight of its ROMs at least. 2016-01-06 23:14:36 -05:00
Thomas Harte
616dc0b57c Okay, so this is the absolute bare minimum about of refactoring and wiring necessary to get the [unimplemented] Electron machine pumping. 2016-01-04 23:40:43 -05:00
Thomas Harte
43ab8bbad5 Okay, so then here's a first shot at the Objective-C -> C++ bridge for the Electron. 2016-01-04 23:16:37 -05:00
Thomas Harte
ab45c1d530 Started working on a shell for the Electron emulation, including factoring out the common CRT delegate -> Objective-C bridging, serial dispatch queue and frameskipping logic from the Atari 2600 shell. 2016-01-04 23:12:47 -05:00
Thomas Harte
aa0714fe27 Started sketching out an Acorn Electron emulation, as it's a platform I'm familiar with and will force me to figure out PAL decoding. Factored out NTSC-specific parts of the display decoding logic and hence added RGB output mode. 2016-01-03 20:41:43 -05:00
Thomas Harte
bc805a90fe Wired up joystick directions, at least, and fire button presses get as far as the C++. But there's some latching to figure out before they'll work. 2015-08-18 20:33:24 -04:00

a693c081f8 Switched on the appropriate compiler warnings re: signed comparisons and implicit conversions. Fixed all less-than-explicit calls. 2015-08-16 16:08:29 -04:00
Thomas Harte
d19f8ed507 Removed the implicit reset upon 6502 startup, adding a reset line. Hence all tests now pass again. Added an empty shell for timing tests, the all-RAM 6502 now counting bus cycles. 2015-08-13 00:51:06 +01:00
Thomas Harte
3c25ead1f3 Started working out some of my retain cycles and general failures to release. Switched .mm filename so that Xcode will stop getting confused when I try to switch between implementation and interface files. 2015-07-27 21:15:10 -04:00
Thomas Harte
6252f6030f Switched to idiomatic source name, ensured latest project name is in all appropriate header places, threw texture coordinates slightly into the shader mix. 2015-07-26 15:25:11 -04:00

ecb2898bd5 The overall architecture of who has responsibility for what is now very askew but: the CRT now outputs a tightly packed short buffer, with the probable OpenGL destination in mind. So it's now all fixed arithmetic internally. CRTFrame is reduced to a plain C struct with the intention that the OpenGL view will take responsibility for it and stop doing the back-and-forth sprint on getting buffer data. The Atari 2600 now outputs explicit blanks rather than level blacks for its border, so that it's easier visually to debug the CRT in its form as far as it has currently progressed: to drawing lines where the cathode ray gun would run while outputting pixel. I note that I'm still not quite getting vertical sync right yet — I'm just accepting it anywhere in teh frame — but that should be an easy fix. 2015-07-24 23:29:45 -04:00

2d0f861474 Incoming: a 'CRT' class, to receive information intended for a cathode ray tube. To decode sync, etc. 2015-07-19 13:36:27 -04:00

e0aa1e9f19 Minor project rearrangement to aid findability. 2015-07-17 09:10:23 -04:00
Thomas Harte
1df2c48668 Introduced my GL view as the window content. 2015-07-16 21:01:49 -04:00
Thomas Harte
5160b6bbb8 Separated out different test suites into different XCTest subclasses. 2015-07-16 20:52:16 -04:00
Thomas Harte
3e0679235a This now goes just far enough to create an instance of Atari2600::Machine and push a ROM to it. Next jobs are to get a basic CRT emulation wired up, outputting to the window. 2015-07-16 20:40:46 -04:00

24c0579b94 Shuffled things and guessed at things until the Xcode project was happy being subservient to the project proper. 2015-07-16 20:27:31 -04:00
