i was going to bridge off some leads for the IR/LED but thought it; i don't care for either and it's a hassle anyhow when all you get is a led to tell you when the computer is on and an IR for a remote i wouldn't use anyhow.
as for replacing BGA chips... no ing way!
i used to mod psx back in the day and now just mess around with personal projects on pcb's but never did i want to attempt what i did last night. it wasn't all that hard but definitely difficult to see considering how small the pads are on that motherboard.
