Notably, an issue in the 3DS version that would lead to the 3DS crashing when exiting the emulator, and an issue that would lead mGBA to appearing in a language other than English by default on macOS despite the system language being set to English, have been fixed. The previously mentioned bug with Advance Wars is still present in 0.8.4. It has also been discovered to affect Final Fantasy I.
