goyuken acc9806d55 2600: add fake mDPC.cs to fix compile. 2012-10-30 22:14:31 +00:00
adelikat ca86a8dff3 Atari - start DPC mapper (Pitfall 2) - only does the basic bankswitching right now, still needs the 2k display bank and DPC sound chip 2012-10-30 01:33:56 +00:00
pjgat09 dfb45aa99c A2600: Fixed graphics on games including Enduro and Activision Boxing 2012-10-26 03:44:13 +00:00
pjgat09 bff6ac53d7 A2600: Fixed issue with vsync which caused flashing in Pleaides and Enduro 2012-10-26 01:50:08 +00:00
pjgat09 ce930374de A2600: Added very basic paddle support. Changing a hard coded value while debugging the emulator allows you to move the paddle. 2012-10-24 03:30:02 +00:00
adelikat 5309bea951 Add some docs for atari 2600 & 7800 mappers, slight fix to 7800 core 2012-10-24 01:47:04 +00:00

adelikat 9c047b34b4 oops 2012-10-23 03:47:00 +00:00
adelikat 427a80548c Start an atari 7800 core based on emu7800, if you have bios files in very specific locations and filenames, you can open 2k ntsc games, and watch with no sound or controls! 2012-10-23 03:33:57 +00:00
adelikat 9a1cbbb34c Atari - attempt the 3E mapper, seems broken 2012-10-20 01:51:38 +00:00
adelikat 4f045eb20d Atari - a stab at implementing mapper m4A50, don't work, oh well, the mapper is garbage and overly complicated, and can't really exist 2012-10-20 00:14:28 +00:00
adelikat 90a288afeb Implement X07 mapper 2012-10-19 23:31:42 +00:00
adelikat 162932797b Atari - make 4Pak use the F6 mapper (header wants 4IN1 which I couldn't find any info on). F6 makes it playable it seems. 2012-10-19 21:33:23 +00:00
adelikat 563065d054 AtariHawk - fixes to the E7 mapper, still broken, don't know why, tired of looking at it 2012-10-19 00:13:39 +00:00
adelikat 00934939b0 AtariHawk - implement mapper 3F (including support of 512kb for homebrew) 2012-10-18 22:22:09 +00:00
adelikat 826419a0a3 AtariHawk - don't flag a frame as lag if the control switches are being read 2012-10-18 19:45:44 +00:00
goyuken 556d428406 atari: fix mapper F0 (megaboy). game appears to be playable 2012-10-15 15:17:20 +00:00
goyuken 591857ad0f atari2600: show what mapper is in use in romstatusdetails 2012-10-15 15:13:32 +00:00
adelikat f7c6659b76 Atari - Mapper E7 - small fix, the games still don't work but it may or may not be this mapper, need to look into it more 2012-10-15 14:29:13 +00:00
adelikat 6fedb67949 Fix the Write callback for the MemoryCallBackSystem and refactor the object more appropriately 2012-10-14 14:08:25 +00:00
adelikat 98ae0abe28 Lua - Implement onmemoryread() and onmemorywrite() to the remaining C# cores except Genesis 2012-10-13 20:15:28 +00:00
goyuken b40897bb77 sound api changes. added a new ISyncSoundProvider, which works similarly to ISoundProvider except the source (not the sink) determines the number of samples to process. Added facilities to metaspu, dcfilter, speexresampler to work with ISyncSoundProvider. Add ISyncSoundProvider to IEmulator. All IEmulators must provide sync sound, but they need not provide async sound. When async is needed and an IEmulator doesn't provide it, the frontend will wrap it in a vecna metaspu. SNES, GB changed to provide sync sound only. All other emulator cores mostly unchanged; they just provide stub fakesync alongside async, for now. For the moment, the only use of the sync sound is for realtime audio throttling, where it works and sounds quite nice. In the future, sync sound will be supported for AV dumping as well. 2012-10-11 00:44:59 +00:00
goyuken 19e5325afa DCFilter: allow variable filterwidth. 2600 tia: use a rather aggressive (~172hz cutoff) dc filter. this coefficient is reasonably close to actual hardware behavior. 2012-10-10 00:56:48 +00:00
goyuken ac86041b94 2600 tia: octave up 2012-10-10 00:24:15 +00:00
goyuken 494f1bdbb5 diced up TIA audio into tiny bits. GHOSTBUSTERS!!!! also, i have no idea what i'm doing 2012-10-10 00:16:38 +00:00
goyuken 8cb8879212 implement some more audio stuff in 2600 tia. many things still undone 2012-10-08 23:30:17 +00:00
goyuken b545d79fb6 lua: add emu.on_snoop() 2012-10-06 13:34:04 +00:00
goyuken 35013f07e8 2600: stop emulator from hanging, consuming all ram, and then crashing in some situations 2012-09-22 19:47:25 +00:00
goyuken 51fc8e695c add 'bool rendersound' to IEmualtor.FrameAdvance()
if false, the emulator is free to gain whatever speedup it can by not doing audio processing (shouldn't change anything sync related, though)
the core should still always call SoundProvider.GetSamples() after each FrameAdvance(), else DRAGONS
at the moment, only test-implemented in gambattehawk
2012-09-20 19:52:47 +00:00
goyuken 83e145c36f change the IEmulator saveram interface.
i don't like doing this, but there were already two emus with special bandaid logic in MainForm.cs
i hope this doesn't break something, but if it does i'll fix it

pjgat09 78de49c923 Atari: Added an audio object to the TIA, including functions to run the 4 and 5 bit LFSRs. Also added some code for the first 4 audio modes, enough to generate samples for one of the audio channels.
Added a logic simulation of some parts of the TIA, including the audio portion. This requires logisim to run.

beirich b599c69c18 Add VirtualWidth to IVideoProvider and the (numerous) implementations. This is just phase 1, client needs to be updated to utilize this information, and some cores (especially PCE) should be updated in a more involved way to provide better TV emulation. 2012-06-25 02:50:34 +00:00

adelikat ea2bdac456 Fix an exception from commit 2161 (Prevent lua script restart when resetting a game). Fixed by making RecentFiles.GetRecentFileByPosition() more robust by not crashing when there is no recent file (returns "") instead 2012-04-04 02:23:47 +00:00
pjgat09 b5927b1212 Atari M6532: Turned the timer into an object, and now uses a prescaler, replacing the previous 32 bit int implementation.
Fixed a typo with the interrupt flag. 
These changes fix freezes with "Berzerk (1982) (Atari)" and "Omega Race (1983) (CBS Electronics)"
