XQuader via Reddit informs us of a GBA Core update that he has been working on to fix a problem that he had since previous versions of GarlicOs.
This is what he says in his post:
mGBA core in the Garlic OS 1.4.9 is very outdated, it was built upon source code dated Feb 22, 2022, because of an odd audio issue that appeared, when Black-Seraph tried to compile a fresh version of the core (see the changelog of Garlic OS 1.2.9).
I’ve managed to fix the issue and compile the core from the latest source code. Along with this core, I also decided to compile the latest gpSP core.
Pay attention, that save states from the old mGBA core will be incompatible with the new one – the game may not start or may have audio issues. Launch the game using the Start button to avoid loading auto-savestate and load an in-game save.
