From the developer:
mGBA is an emulator for running Game Boy Advance games. The application features fast emulation, so that the games can run at full speed even on low-end hardware, such as netbooks. It provides Qt and SDL ports for a heavy-weight and a light-weight front-end.
You may want to check out more Mac applications, such as iClanASC, Rawr or wordSword, which might be similar to mGBA.
