Use the following code to display a debug menu; the menu appears like an arcade operator test menu, except text other than Exit have been dummied out.
Press Start (while still highlighting option 8) to enter an I/O TEST menu, which works like an arcade input test menu, although it does not test for face buttons.

In the Japanese version, Doctrine Dark's throw move will have him place an explosive on the opponent's throat, causing them to be lit on fire when it explodes. Similarly to Street Fighter EX, his throw is replaced with a more generic backwards toss in other regions.
In the options menu, the button configuration section is titled "Key Config" in Japan and "Button Config" in other regions. A screen setting option was added to the options menu of the US/Europe versions and there is a more detailed description about how to enter and exit the options menu at the bottom (you must press Select in the Japanese version to exit and Start in the US/Europe versions).
An autosave option is exclusive to the Japanese version, but is missing overseas.
