Just curious what you mean by "fixing the audio"? In GBA emulation or on the hardware?

I'm aware that if you need/want PCM audio, there's going to be mixing, probably with a software library, and significant CPU use for it. Is emulated GBA audio buggy?

One of my first gigs was Game Boy and Game Gear programming. I know the GBA allows DMG audio compatibility and, with all its constraints, well it sure does keep things simple. And emulation is reliable AFAIK.

I see what happened, I was replying to a different comment, that did mention the GBA audio, when I wrote that, but somehow ended up replying to this one.

This comment explains it better than I could: https://news.ycombinator.com/item?id=47708201
