After you beat Bison with Sagat you have the usual screen as if you beat any other opponent, but not the end. Shortly afterwards the game crashes. and I tried to get his ending on all the versions both ECS and AGA. I assume the CD32 never came out.
If someone could make a .dat file with all the in-game texts that would be helpful. The ending might be somewhere, but since it is not playtested well you can't see it when you beat the game. You probably can see it if you hack the game or something like it...
