Everything should fit. The thing in the middle is where the GBA sp plugs in.
My atari is screwed up. I think I fried the sound chip. (Cant remember what its called but I think its the stella)
Anyway so all I got when I hooked it up was a sound like "GHHH GHHH GHHH GHHH" so that kinda sucks.
Im ordering a new one from that place with the cheap chips (the one in the "atari2600.com thread") and its going to cost me $30, but its still cheaper than ebay so Im ok with that. Anyway Ill update again when something happens.
(BTW I fried a bunch of other stuff on the board so thats why Im buying a new one.)
