Goomba Color is a GBC emulator written for the GBA. Even though the GBA usually natively plays GBC games, Goomba Color provides the convenience to run multiple games from a flash cartridge, and also runs on the Nintendo DS and Game Boy Micro.

Changes:

* Fixed double speed timers mode
* Adds SGB borders to games which support both GBC and SGB mode
* Fixed controller input in SGB mode
