I recently released a restoration hack for the SNES port of Street Fighter Alpha 2 that restores the red blood and Sodom’s name back to the international versions of this game, you can check it out here: http://www.romhacking.net/hacks/4687/
But I recently discovered that the background stages for Birdie, Guy and Sodom are censored in the international versions, here’s what they look like in the Japanese version:
On Sodom's stage, his truck has his name on the license plate and the trailer:
On Guy's stage, the word "KILL YOU" appears on the wall:
On Birdie's stage, there's two people peeing in the urinals and when you use a super move, the left stall opens:
The problem is I don’t know how to restore them, that’s why I’m looking for a hex editing expert that can help me on this. I also think some of these graphics are still in the international versions, but they’re disabled.
If someone can help me on this, that would be great.
