Final Fight 2

Capcom finally makes a version of Final Fight on the SNES that has 2-player co-op, three playable characters and Rolento in it. Then they realized that this is the third version they made of the game on the SNES, so they changed all the stages, replaced every character except Haggar and the Andores, slapped a number "2" on the title and called it a sequel.

Unused Enemies
Two extra Andore variants are listed in the game's enemy list, but are only semi-programmed. F. Andore and U. Andore have their life bar and name programmed in, but when placing them in the game itself, they're highly buggy and prone to crashing or freezing the game. Nevertheless, they are semi-programmed in, seemingly using the Andore AI, but why they don't work right is currently unknown.

U. Andore

F. Andore

 * 84C26604

Version Differences
Several changes were made between the Japanese and American versions. Some are obvious, some are not.

Graphics
A minor, though interesting change. Won Won has a cleaver that is taken out of the American version. A chopping sound effect still plays when he connects with it in the US version, though. No explanation for the change.

Final Fight 1 wasn't the only Final Fight edited to remove women, as these edited sprites show. Note that while Robert essentially has a similar palette to Eliza's, Leon gained a whole different palette!

Sound Test
The SFX portion of the American version stops at 3F, while the Japanese version goes up to 49! And yet it gets stranger, as the Japanese version has ten sound clips that don't play anything at all when selected! The numbers of those are as follows:

00, 17, 18, 19, 1A, 21, 28, 3A, 3B, 3D.

Some of these are mixed in with voice clips, but some of them aren't. No idea what they could have been either way.

It seems that someone took the time to fix this situation up for when it reached America. Good call.
