Gaming How did game devs emulate GB sound channels when making music for a GBA game?

[biolizardshadow]

The square channels interact with each other in very unique ways; however, the Noise channels is something else. As an individual who has tried to emulate it using samples (pretty much because I don't have any knowledge about programming) it is very hard to determine what sound is associated with what note when you are making a song.

If anyone has any insight into that process it would be helpful.

Iirc GBA games have access to the original GB audio hardware as part of the BC, similar to the MD/Gen and it’s PSG channels.

When they would insert a note into their music program how did they know if that would translate to the PSG channels especially for the wave and noise channels?
