- This version adds major accuracy improvements, countless bugfixes and DSP-1 support. At the time of this release, the only remaining known bug in bsnes is with Uniracers 2-player mode, with well over 300+ games tested.
Changelog:
- DSP-1 support added [Andreas Naive, byuu]
- Added cooperative multithreading library, written by myself
- Rewritten CPU core, now bus accurate
- Rewritten APU core, now bus accurate
- Added cartridge database
- Added several PCB mappers, thanks to research from Overload
- Added several games to database, fixing several mapping-related bugs
- Improved mirroring [Nach, grinvader, byuu]
- vscroll bug in hires, interlaced mode fixed. Fixes RPM racing
- RTO X=256 bug corrected. Fixes Super Conflict title screen [anomie]
- Fixed bug in NTSC filter with hires games
- Updated snes_ntsc to version 2.0.1 [blargg]
- Fixed bugs in HiROM / LoROM memory mapping. Fixes countless games
- Fixed major bugs in HDMA routine. Fixes ToP, Mortal Kombat and Genjuu Ryodan
- Added out-of-order execution to CPU, APU synchronization for major speedup with no accuracy loss
- IRQs are now delayed after H/DMA transfers. Fixes Wild Guns
- HDMA transfers now kill active DMA channels that are on the same channel. Fixes Bugs Bunny and World Class Rugby. Special thanks to zones for researching this
- CPU emulation mode accuracy was improved
- Cleaned up port-specific code to ease porting
- Created unified Makefile, used by all ports [Nach]
- Created GTK+ port of bsnes (although input is currently broken)
- WRAM is now initialized to 0x55, SRAM to 0xff. Fixes Power Drive, Death Brade and RPM Racing
- Fixed extreme NMI / IRQ edge case. Fixes Chou Aniki
- Adjusted PAL execution speed. Fixes Earthworm Jim 2 (E) sound effects
- Fixed auto joypad polling bug. Fixes La Wares
- Fixed H/DMA bug that was preventing saves from working in Secret of Evermore
- bsnes low loads d3dx9_*.dll dynamically at runtime, it is no longer required
- Added support for 239-line PAL mode rendering
- As usual, there have been much more changes I've forgotten about since the last release

bsnes Version 0.017 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. Known Bug(s) ------------ Uniracers / Unirally - 2-player mode sprite issues (mid-frame OAM writes not supported) Known Limitations ----------------- S-CPU - Invalid DMA / HDMA transfers (eg WRAM<>WRAM) not fully emulated - DMA / HDMA bus synchronization timing not supported - Multiply / Divide register delays not implemented S-SMP - Cycle breakdown of opcodes is theoretical, but mostly correct S-PPU - Uses scanline-based renderer. This is very inaccurate, but very few 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 S-DSP - Runs at 32khz. Hardware S-DSP likely runs at 1.024mhz to perform multiple reads / writes per sample. Sound is still output at 32khz, of course Hardware Bugs - CPUr1 HDMA crashing bug not emulated - CPU<>APU 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 SPC7110 Coprocessor used only by the following games: - Far East of Eden Zero - Far East of Eden Zero: Shounen Jump no Shou - Momotarou Densetsu Happy - Super Power League 4 DSP-3 Coprocessor used only by SD Gundam GX DSP-4 Coprocessor used only by Top Gear 3000 ST010 / ST011 / ST018 SETA coprocessors used by very few games BS-X (Broadcast Satellite) Add-on unit sold only in Japan that played specially-made games that were downloaded via satellite BS-X Flashcart Flash cartridge used by BS-X, as well as some standalone games by Asciisoft Bandai Sufami Turbo Special cartloader to play some Bandai games Super Gameboy Cartridge passthrough used for playing Gameboy games Unsupported controllers ----------------------- Mouse Super Scope Justifier Multitap (4-port) Multitap (5-port)
