i am not sure if this is the right place to post this, but ive been looking all over the net and am hoping someone here has some info i can use. I am building a portable n64. It has been done before. but the amount of info available isnt much. so far all i can find is how to build a portable NES, Atari, and PSOne. what i want to know is, how can you hook up a battery to the deck. i found the pinouts for the power on the main board. if anyone has any info, please tell me.
