About

Sonic Advance 3 is a 2004 Game Boy Advance platform game developed by Sonic Team and Dimps, in which Sonic, Tails, Knuckles, Amy, and Cream work to stop Doctor Eggman and his robot assistant Gemerl from building empires across seven divided regions of Earth. This is a work-in-progress matching decompilation of Sonic Advance 3, currently able to build the European ROM release. It requires a copy of the original Sonic Advance 3 ROM to build against.

Getting started

Place a copy of the original Sonic Advance 3 ROM in the repository root under the filename the build expects, then follow the build instructions using an up-to-date compiler fork.
