Update to bsnes v031 release.
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

- 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

Update to bsnes v025 release.
bsnes is exactly three years old today. I've posted a new version which adds DSP-3 and DSP-4 special chip support. The DSP-3 is used by SD Gundam GX, and the DSP-4 is used by Top Gear 3000. Please note that the DSP-3 is not fully emulated, thusly SD Gundam GX is not fully playable. Also, due to lack of timing emulation with the DSP-4, the Top Gear 3000 track sometimes flickers in split screen mode. However, it is believed that Top Gear 3000 is fully playable.
I should also note that I have started on SuperFX emulation, as some will inevitably see said code in my source releases. What I have now is nothing more than a skeleton implementation, and absolutely nothing using it is playable yet. I am making absolutely no promises that I will ever be able to emulate this chip. It will take at least several months of work, and even then, the speed will probably be too slow to reach 60fps on any system, but ... I'm working on it. While I have no way to run tests on the actual SuperFX hardware, I will do the best I can to emulate the chip accurately. I will be emulating the caching and cycle delays as best I can, but the information I have on this chip is extremely limited, so don't expect miracles.
Lastly, as promised, I have released the special chips I have personally emulated to the public domain. See license.txt for more information if interested. I cannot release the special chips whose code I did not write to the public domain, but all of that is already available under the GPLv2 (from ZSNES) or the SNES9x license.
Changelog:
- Added DSP-3 support, thanks to John Weidman, Kris Bleakley, Lancer, z80 gaiden
- Added DSP-4 support, thanks to Dreamer Nom, John Weidman, Kris Bleakley, Nach, z80 gaiden
- Started on support for SuperFX, no games playable as chip emulation is less than 1% complete
- Unsupported special chips will now display an alert
- Missing stbios.bin file when loading Sufami Turbo cartridges will now display an alert
- Video settings now saved separately for windowed and fullscreen mode
- Advanced option video<.mode>.synchronize can be enabled for vsync, but will cause sound crackling
- Added menu option to toggle FPS counter
- Minor source code cleanup
