mGBA v0.8.4


Total votes: 9

A new release of mGBA, version 0.8.4, is available. This version is a bugfix release, which contains many stability and accuracy fixes. 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. This can be worked around by using a dump of the official BIOS, or using a development build, also available on the download page, which has the bug fixed. An extensive list of changes follows after the cut.
