After a small excursion into the game, I have determined that general pepper's text is very dangerous, and will very likely transform your ship into a different ship if you go from walker to plane while his text is transitioning. The purpose of this thread is document glitches like this.
Remember, those could just be the more notable fixes. Not all programmers write down every single change when they make a patch
And for the heck of it, I'm not mod but I'd say that it should be required to label whether you run on SNES or EMU
Me and liam have decided to use a new ROM that includes a fix that makes the game MUCH less laggy. I'm probably gonna get shot by the TOS here, but look for the rom on emuparadise that says "Star Fox 2 (Japan) (Proto) (Alt 1) [En+Hack by Aeon Genesis v1.0] [Fix by ManuLoewe] (Final Version)"
