New release posted. Perhaps the most important change was fixing a bug in the Windows port when the keyboard was used for input. For some reason, the IsDialogMessage() function I use for tab key support was causing the main window to emit the Windows error beep every time a key was pressed after a few minutes of use. I do not know why this is, so I have simply disabled the tab key support to prevent this from happening.
Other than that, lots of polishing went into this release. UPS soft-patching will work with the recently released Der Langrisser v1.02 translation, for those curious. You can also store the UPS patches in GZ/ZIP/JMA support, and bsnes will detect this and decompress the patches first. Use the same ".ups" file extension for this, as it detects via file header.
If you wish to try out the newly added OpenGL support: start bsnes, go to Settings->Configuration->Advanced and set system.video to "wgl" (or "glx" for Linux users), and then restart the emulator. Please bear in mind that ATI's OpenGL drivers are an industry-wide joke, so I'd only recommend trying this on an nVidia or Intel video card.
Changelog:
- Fixed bug and re-enabled HDMA bus sync delays
- Emulated newly discovered IRQ timing edge case
- Optimized offset-per-tile rendering
- Added state-machine implementation of S-DSP core, ~5% speedup
- Added SPC7110 detection, will now warn that this chip is unsupported
- Fixed very annoying Windows port OS beeping noise when using keyboard for input
- Linux port will now save most recent folder when no default ROM path is selected
- Added OpenGL rendering support to Windows port [krom]
- Fixed Direct3D pixel mode scaling bug [krom, sinamas, VG]
- Improved SNES controller graphic [FitzRoy]
- Added UPS (not IPS) soft-patching support; UPS patch must be made against unheadered ROM
- As always, cleaned up source code a bit

bsnes Version: 0.031 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 Limitations: ------------------ S-CPU - Multiply / divide register delays 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 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 ST-011 SETA DSP used only by Quick-move Shogi Match with Nidan Rank-holder Morita ST-018 SETA RISC CPU used only 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 Multitap (4-port and 5-port)
