mGBA is a Game Boy Advance emulator written in C. The project started in April 2013 with the goal of being fast enough to run on lower end hardware than other emulators support, without sacrificing accuracy or portability. Even in the initial version, games generally play without problems. It is loosely based on the previous GBA.js emulator, although very little of GBA.js can still be seen in mGBA.
