General:
|
|
--------
|
|

Known Limitations:
|
|
------------------
|
|
S-CPU
|
|
- Invalid DMA / HDMA transfers (eg WRAM<>WRAM) not fully emulated
|
|
- Multiply / Divide register delays not implemented
|
|
|
|
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
|
|
|
|
Hardware Bugs
|
|
- CPUr1 HDMA crashing bug not emulated
