From what i think i understand so far:
The genesis model 3 has 2 different revisions. a mono version and a stereo version. easy way to tell is if you have a stereo genesis plug. just plug it in and see if you get sound out of 1 or 2 speakers. I cant do this since i dont have stereo AV Cable... I only have mono.
If its mono then you need to build an amp. which i dont know how to do and i dont understand electrical schematics well enough. I think the genesis model 3 has 3 channels... left, right, and sound effects. so if it is stereo i just need to find out how to merge the 3 channels into 2 and divide the sound effects to both left and right. I also needs the solder points to tap into.
My progress so far:
