PC version Fans have made a PC version. Some are still early, so read the project page first.
Fans took SD Gundam: Dimension War apart and rebuilt it so it runs natively on a computer, often with widescreen, higher frame rates and mods. Here is the project we know about:
Early prototype Virtual Boy recompilation with recomp-ui and opt-in English, color, and adaptive widescreen mods. Bugs expected. Requires the original Japanese ROM.
