Changelog:
- Added S-DSP emulation
- Added sound output support via DirectSound -- no sound buffering though, so sound is muted by default
- Added option to record raw sound output to WAV files
- Added multiple color adjustment filters to the video output
- Added mode3/4 direct color support
- Added mode7 direct color and mosaic support
- Greatly improved mode7 rendering algorithm thanks to anomie
- Fixed mode7 screen repitition and EXTBG effects
- Greatly increased accuracy of NMI and IRQ timing, and emulated many newly discovered hardware quirks involving the two
- A few speed improvements courtesy of Nach for profiling the code for me
I'm now looking for assistance with sound buffering. Specifically, I need help modifying the DirectSound code to allow the emulator to be ran between 50%-400% normal speed, while keeping the sound output relatively good. If you have experience with this and can help, please get in touch with me (setsunakun0 at hotmail dot com).
bsnes now supports SPC700 emulation (no DSP or sound support, however), and has greatly improved compatibility. It also now contains a keyboard-only joypad configuration tool.
The rewrite is now complete. I finished adding frameskip, and fixed some crashing issues with loading multiple ROMs. I wrapped all malloc/free calls with memalloc/memfree, which are custom functions that log each call, and let you pass sprintf-style arguments to them to debug memory leaks. Don´t see any, nor have I noticed any in bsnes; but it makes a nice test tool anyway.
I found out today that the mvn/mvp instructions actually set the DB register to the destination bank. Weird. This fixed Final Fantasy V, Chrono Trigger, and Dragon Quest III (which now runs as a result) graphics. Not all of them, but quite a few. I had also previously been setting the M/X flags of the P register when xce was executed. I never anticipated a game using xce while in native mode to switch to... native mode... but apparently, Chrono Trigger does. And my code was incorrect. So now Chrono Trigger gets past the name select screen, but dies a few screens after still.
The only really major flaw I am aware of that bsnes v0.005 did not have is with the battle screens in Squaresoft games. I get horrible flickering and "crushed scanlines" every other frame on them, for some reason. I´ll try and track that down for the next release, but I didn´t want to hold up a new release any longer. As a result, I´ll leave up v0.005a for the time being until I get this problem fixed.
