Re: Bushwhacker's N64p Log; UPDATED 12/12; please help
Yes, you can, but then you would need two regulators. The 12v line on the n64 can use 7.2v, and the psone screen can also run off of 7.2v. So if you use a battery that is 7.2v, you only need one regulator to step the 7.2v down to 3.3v just for the 3.3v line for the n64.
