(N64) Mickey’s Speedway USA

Racing game based on karts and characters from Disney, it’s one of the last game published in Japan on Nintendo 64, being released in 2001.
Developed by Rare, it’s based on their Diddy Kong Racing engine and features 6 characters (Mickey, Minnie, Donald, Daisy, Goofy and Pete) plus other 4 unlockables; tracks are based on real locations in the U.S.A. such as New York, Texas, Colorado, Los Angeles and Yellowstone Park.
The Japanese version cannot be linked up to the Gameboy Color game (because it was not published in Japan) so the 4 hidden characters can be unlocked by winning the 4 different Cups.
