F-1 World Grand Prix (Prototype)
Discuss this release on the boards here!
A new release for this week!
This is a prototype of F-1 World Grand Prix for the Game Boy Color that Techokami snatched on a Japanese auction recently. This prototype contains many differences in comparison to the released European version. Special thanks to Techokami, MarioDS64, Naoshi, and ORCACommander for this release!
Enjoy!
