For some bizarre reason, the Old Capital and the Material Factory were switched around...

Japanese	American
...so in the American version, the Material Factory is Area 1 and the Old Capital is Area 3. In Japan, the Old Capital is Area 1 and the Material Factory is Area 3.

Due to the Old Capital and Material Factory being switched around, some enemies in the stages are moved around, and some were replaced altogether. This is also reflected in the ending sequence. "Tank" replaces "Chin". "Dust Cannon" replaces "Kan". "Ten" was replaced with "Pot" (see below). Also, for some strange reason, some enemies' names have been changed. "Ton" became "Cannon".

The "S Ball" sprite was changed slightly. The blue glow was taken out of the middle of "C 01", "C 04", and "C 08". The palette for "Box" was changed from light brown to gray.

"Momcy" was renamed "Mumoky", "Mush" became "Musha", and "Hoocy" became "Hooky".

I have no idea why, but "UFO" was renamed "YUFO".

Japanese	American
I have no idea why, but the "Tank" and "Cannon" were switched around for the Neo Megalopolis enemy list, and "Yokobary" was renamed "Yokabary".

"Womcy" became "Womacy" and "P Cet" became "Pycet".
