Description
Super FX 3 is here, thanks to the legendary Randy Linden!
This patch converts Star Fox to FastROM and to use the Super FX 3 chip. Enjoy Star Fox with a nice 4x/8x speed boost (depending on which chip you're comparing the FX3 to)!
The Super FX 3 runs about 8x faster than the original 10.7mhz MARIO chip Star Fox shipped with, and about 4x faster than the 21.4mhz GSU-1/GSU-2!
Rumble (From Star Fox Shindou Edition) and optional MSU-1 support (intended for use with the same track map as my previous MSU-1 patch) are included.
No, the game speed is not untied from the framerate, nor has the framerate cap been raised.
The game is now able to hit the maximum 20fps far more often than before!
Currently, only MesenCE supports the Super FX 3. This functionality is not in a stable release as of writing, only in development builds/nightlies. See here for links to MesenCE development builds.
SuperSNES9x also supports the Super FX 3.
Version 1.2 adds patches for Japanese Star Fox. Nothing else has changed.
