Well.. I'm discontinuing this project. I just can't get it how I want it to look and function.
Since I still have the 2 systems and I have a better idea of how to make a portable. I'm using the N64 in my Z64 project, and I'm going to make the GameCube into either a briefcase or a laptop. I hope I don't screw up.
Also, hermaphroditus, I'll still use the battery you made me as a universal battery.
