For this release: SPC7110 emulation speed has been greatly optimized, massive improvements to HDMA timing have been implemented, Multitap support was added, and the user interface was polished a bit more.
Changelog:
- SPC7110 decompression code updated to latest version by neviksti and converted to a state machine; SPC7110 overhead is now identical to S-DD1 overhead (eg ~5% speed hit over standard games)
- Fixed a major bug in SPC7110 data port emulation that was crashing Super Power League 4 [Jonas Quinn]
- HDMA trigger point corrected to H=1104, bus sync timing corrected
- All illegal DMA A-bus accesses should now be properly blocked
- DMA state machine rewritten, greatly simplified
- Major corrections to HDMA run timing; fixes flickering bugs in Mecarobot Golf and Super Mario Kart
- Emulator now defaults to 2/1/3 SNES (CPU/PPU1/PPU2 revision numbers)
- Multitap emulation added, can be attached to either or both controller ports; user interface updated to reflect this
- Status messages (cartridge loaded / unloaded, UPS patch applied, etc) now appear in status bar
- Added advanced configuration option, "input.analog_axis_resistance", to control gamepad analog stick sensitivity
Also, the SPC7110 emulator download link below was removed: if you are looking for this, please download the bsnes v034 source code, which has the most up-to-date version in the src/chip/spc7110 folder.

bsnes Version: 0.034 Author: byuu ======== General: ======== bsnes is a Super Nintendo / Super Famicom emulator that began on October 14th, 2004. The latest version can be downloaded from: http://byuu.org/ Please see license.txt for important licensing information. ============== Configuration: ============== bsnes has two configuration files: bsnes.cfg, for program settings; and locale.cfg, for localization. For each file, bsnes will start by looking inside the same folder where the bsnes executable is located. If said file is not found, it will then check your user profile folder. On Windows, this is located at "%APPDATA%/.bsnes". On all other operating systems, this is located at "~/.bsnes". If said file is still not found, it will automatically be created in your user profile folder. If you wish to use bsnes in single-user mode, be sure that both files exist inside the same folder as the bsnes executable. If they do not, you can simply create new blank files and bsnes will use them in the future. If you wish to use bsnes in multi-user mode, simply delete these two files from the bsnes executable directory if they exist. If you wish to have multiple configuration profiles for the same user, you will need to make copies of the bsnes executable, and use each one in single-user mode. ================== Known Limitations: ================== S-CPU - Multiply / divide register delays not implemented - "Glitch" when reading joypad registers during auto polling not implemented S-PPU - Uses scanline-based renderer. This is very inaccurate, but few (if any) games rely on mid-scanline writes to function correctly - Does not support FirstSprite+Y priority - OAM / CGRAM accesses during active display not supported correctly - RTO flags are not calculated on frames that are skipped when frameskipping is enabled. This provides a major speedup, however it will cause in issues in games that test these flags, eg the SNES Test Program Electronics Test. Turning frameskipping off will allow RTO flag calculation on every frame Hardware Bugs - S-CPU.r1 HDMA crashing bug not emulated - S-CPU<>S-SMP communication bus conflicts not emulated ===================== Unsupported Hardware: ===================== SA-1 Coprocessor used in many popular games, including: - Dragon Ball Z Hyper Dimension - Kirby Super Star - Kirby's Dreamland 3 - Marvelous - SD Gundam G-NEXT - Super Mario RPG Super FX Coprocessor used in many popular games, including: - Doom - Star Fox - Star Fox 2 (unreleased beta) - Super Mario World 2: Yoshi's Island ST-011 SETA DSP used by Quick-move Shogi Match with Nidan Rank-holder Morita ST-018 SETA RISC CPU used by Quick-move Shogi Match with Nidan Rank-holder Morita 2 Super Gameboy Cartridge passthrough used for playing Gameboy games ======================== Unsupported Controllers: ======================== Mouse Super Scope Justifier ============= Contributors: ============= Andreas Naive, anomie, blargg, DMV27, FitzRoy, GIGO, Jonas Quinn, kode54, krom, mudlord, Nach, neviksti, Overload, RedDwarf, Richard Bannister, tetsuo55, TRAC, zones
