Regional Differences
In the Japanese version, after beating the last boss, your character will do their win pose and you'll see an ending epilogue. Each character has one. However, in the non-Japanese versions, the text was removed and your character just stands there while you enter your hi-score name.

Additionally, M. Bison (the dictator) is known as Vega and Akuma is known as Gouki in Japan.
