In the Japanese version, the test battle in the debug room features a proper background and models for the enemies included (borrowed from other enemies), whereas the international version simply pits the party against yellow pyramids in a black void.

Additionally, the very first Japanese release contains an unfinished eleventh section of the debug room, left over from an earlier build of the game. Because the game's code changed significantly since that build, much of the eleventh section is broken: Cloud's model does not show up (though he is still able to move around and interact with the NPCs there), text is corrupted, and the background music is a heavily distorted version of Aeris' theme.
