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
