mGBA is an open-source emulator that supports Game Boy Advance emulation, with later revisions adding backwards compatibility with Game Boy and Game Boy Color. The emulator is written in the programming languages C, and is designed for Microsoft Windows, macOS, Linux, Ubuntu, and FreeBSD. Official ports on Nintendo 3DS, Nintendo Switch, Wii, and PlayStation Vita were released through homebrew applications.

mGBA initially gained criticism due to the existence of other capable Game Boy Advance emulators such as the VisualBoyAdvance. After multiple revisions and continued support, the mGBA has since experienced a rise in popularity, with its core being used in multi-system emulators such as OpenEmu, RetroArch, and BizHawk. The emulator is also compatible with Dolphin, implementing the Game Boy Advance link cable through connectivity with GameCube games.[3][4]

History

[edit]

In 2012, Vicki Pfau, known as "endrift" online, was inspired to create a Game Boy Advance emulator in JavaScript, hoping to improve on previous emulators such as the VisualBoyAdvance. GBA.js started development in July of 2012 and a beta was published to Hacker News in October of the same year. The JavaScript code would later be converted to C, with the hopes of the software communicating on native hardware and being able to run competently on a Raspberry Pi. GBA.js would be put on an indefinite hold to focus on GBAc, later titled mGBA. The first version of mGBA, mGBA 0.1.0, was released on December 13, 2014.[5]
