mGBA to emulator Nintendo GameBoy Advance autorstwa Jeffreya Pfau napisany w C, więc powinien w miarę dobrze radzić sobie również na słabszych platformach. Nowa wersja, jak wspomina autor, to zestaw poprawek, które mają poprawić stabilność i kompatybilność aplikacji z emulowaną konsolą.
Dla chcących śledzić na bieżąco rozwój tego emulatora dobrą wiadomością będzie informacja, iż projekt ma swoje "nocne" kompilacje - binarki znajdziecie tutaj
