This popular Android emulator runs on the original GBA engine and offers high-quality graphics rendering.
There’s no other emulators mixed inside of it that you can play around with. This emulator only supported the Game Boy Advanced 2, so you’ll have to find ROMs specifically for that machine. This one might not have nearly as well built and designed of a UI as some others on our list, but it’s basic functions actually work really well. It doesn’t offer nearly as many features as the GBA.emu, but you still get save/load states, hardware support, and a few other features.
GemBoy is another great emulator available - it actually functions as a dual-emulator, offering both Game Boy Advanced and Game Boy Color emulators.
