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).
- Fixed Mode 0 color palette index problem. Fixes ToP, DQ5, etc.
- Improved LoROM memory mapper to support 32mbit images. Fixes Tokimeki Memorial, etc.
- Added full S-DD1 support, SFA2 and Star Ocean are now playable. Special thanks to Andreas Naive
- Updated BGnxOFS / Mode7 registers with anomie's latest findings
- Added basic ROM mirroring support. Fixes copy protection issues in MMX, etc.
- Rewrote string library to work better on gcc/linux
- Cleaned up S-RTC/S-DD1 emulation to make way for future add-on chip emulation
- Rewrote DMA code, now runs cycle-by-cycle
- Rewrote HDMA code, now allows HDMA to be enabled mid-frame, fixes many games
- Fixed a bug in Mode7 vertical screen flip mode. Fixes FF5 title screen, etc.
- Greatly improved IRQ triggering. Fixes Der Langrisser, etc.
- Added full support for open bus. This includes PPU1 and PPU2 open bus support
- Modified CPU core back to cycle-based system. Slower, but improves debugger
- Implemented temporary fix for debugger to handle new cycle-based cores
- Modified CGRAM to ignore highest bit, since it is not used at all by the SNES, and is impossible to read on real hardware. Lowers memory usage by ~1.2mb
- Added mostly accurate PAL timing support. This should increase compatibility by ~30% or so
- More stuff I'm forgetting at the moment...
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.
