ok so i just looked up a bit of research and cracked open my gba.

Looked at the pin layout for the amp chip and traced the lines back to the r30 and r31 resistors. I believe this is what was discussed before.

It should be like this: r31 right and r30 left audio channels.
If you connect to these areas it should bypass the amp circuit.
As far as I can tell the amp comes before the volume pot which is the opposite of the older gameboy models (please correct me if i am wrong). so if you cut the 7 and 8 pins on the amp chip and then take from the resistors and send them to the right and left chanels of the volume pot then you will have an easy internal gba prosound mod. If you add a jack and you dont care about adjusting the volume then you can just ground that that random point i squared (i assume anyways) and go straight to the jack. if you want volume then route it thru the pot and on the other side of the pot route it to the jack. done and done.

jacks fit easy in the back. this is how i had it setup before i fried my gba those years ago.

so just to be clear, i havent tried this mod out yet myself. so try at your own risk.

where is it located and did you make it in a plain text editor?

seriously. i might just do this because i am so used to lgpt and it is actually a really great setup for live triggering while dancing it up.

pulsar has customized mapper that isnt in any emulators. other than that i think they should run the rest.

better to have a specific question then have such a broad research question. if there is something specific about electronic music you want to learn search for that instead of just electronic music.
