e02d109864 Nudges the LowpassSpeaker towards supporting stereo generation. 2020-02-15 18:03:12 -05:00

294e09f275 All these 'override's can be 'final's. 
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

6802318784 Removes audio_queue_.flush() calls; I don't think I really need to block. At least, not usually. 2020-01-23 20:13:16 -05:00

a86fb33789 Ensures that the ColecoVision, MSX and Master System fully flush. 2020-01-22 22:57:16 -05:00

a71c5946f0 Ensures proper manipulation of scan_statuses, leading to the correct result out of a CRTMachine. 
Possibly with the exception of the TMS, as I appear to have uncovered an unrelated issue there.

d97a073d1b Adds the necessary routine for all machines to be able to respond to get_scan_status. 
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.

c1bae49a92 Standardises on read and write for bus accesses. 
Logic being: name these things for the bus action they model, not the effect they have.

8a699b6072 Kills setup_output definitively, saving some indirection. set_scan_target takes its place. 2018-11-14 21:52:57 -05:00

b40211d2c0 Starts to bend 'CRTMachine' to a world farther from owning the GPU relationship. 2018-11-03 21:54:25 -04:00
Thomas Harte
da4d883321 Adds first, incomplete attempts to talk to a ScanTarget from the CRT. 
Does away with the hassle of `unsigned` while I'm here; that was a schoolboy error.
 2018-11-03 19:58:44 -04:00

d1fc39d6e5 Attempts to carry on even if no BIOS is found. 2018-10-26 21:19:16 -04:00
Thomas Harte
a8645f80bf Introduces 'non-exclusive' emulator-space keyboards. 
i.e. sets of keys that don't amount to an entire keyboard in the modern sense. Experimentally used by the Master System for its reset key.
 2018-10-24 21:59:30 -04:00

Thomas Harte
52e02db5c8 Introduces horizontal counter latching and reading. 
Then makes a new guess at frame IRQ position. But gets it wrong. Hmmm.
 2018-10-11 19:56:32 -04:00
Thomas Harte
24644f1dd1 Adds a low-pass filter, picked entirely by ear, and switches to composite output, at least for now. 2018-10-07 18:39:03 -04:00

76f3b9f6ba Fixed: paging writes don't obstruct RAM. 2018-10-06 14:26:00 -04:00
Thomas Harte
7830cda912 Implements line querying and most of line interrupts. 2018-10-04 22:50:35 -04:00
Thomas Harte
e9328d819e Switches to RGB output, at least for development. 2018-09-30 20:47:03 -04:00
Thomas Harte
2e4c4c3e91 Makes some attempt to implement paging. 
This causes several of the 32kb games to be recognised by the BIOS and permitted to start, so it really really may be time to stop deferring work on the VDP.
 2018-09-24 21:34:42 -04:00

7515fa8a98 Ensures the SG1000 gets an unadulterated TMS and SN. 2018-09-23 22:24:29 -04:00

5b9e7213dd Adds a couple of joystick inputs. 
SG1000 titles all seem to work now.
 2018-09-23 21:55:07 -04:00
Thomas Harte
2253341904 This now goes far enough for the only SG1000 game I'm testing to start up. 
Which hopefully gives me as much as I need to implement joypads, etc, and definitively get to just the VDP being outstanding.

e155dc8d6e Adds fairly standard memory map indirection. 2018-09-23 17:36:30 -04:00
