back to rom structure front pageBelow is a table representhing the roms for Gaplus (rev. B) and its clones (if any).
Red roms are similar between all versions but
green roms differ, which means that if you wish to change the game's region or language, it
may be possible make the change simply by reprogramming fresh roms with other version's contents.
Note that the rom information displayed here is automatically parsed from Multiple Arcade Machine Emulator (
www.mame.net) C source code, so some of it can be incorrect. However, if you notice that some parts of the data are constantly incorrectly displayed in more than one game, please
contact me so that I can fix the problem.
You might also be interested in this game's
dip switches.

I realize that command does have its fascination, even under
circumstances such as these, but I neither enjoy the idea of command
nor am I frightened of it. It simply exists, and I will do whatever
logically needs to be done.
