[gba] Mother 1+2 (Japan) Missing Audio Channel and Weird Artifacts #2253
Description
Describe the issue
I noticed that while playing the Mother 1+2 rom the emulator was playing the sound a little off. The original Mother's soundtrack is rooted really deep in my brain so it wasn't hard to notice a difference. So I decided to test the ROM on the mGBA emulator and what I discovered it's that in aresEmu there is, at least, one channel totally missing from the audio track, it's called "PSG Channel 3" in mGBA. If I disable said channel in mGBA the audio becomes closer to the weird one in ares.
I tried changing the audio driver from WASAPI to SDL (wich is what mGBA was using) but that was of no help. Same behaviour.
You can also notice some weird pixel artifacts when the fan translation info screen transitions to white and then to the Nintendo logo.
As this is, mainly, a sound issue I recorded a little sample of this behaviour with OBS comparing both emulators side by side, pausing and/ or muting one and the other. You can check it by streaming on this gofile link (downloading is not needed).

Rom Information
I'm using a translation patched rom. But I tried the original unpatched one and got the same issues.
