For several reasons, the 1.0 release (and maybe the 4.1 prototype too) will have 5V controller ports with level shifting for the I/O pins. While SNES controllers work just fine all the way down to 2V, the mice don't, and if we want to support keyboard adapters they're going to need power too. So I've put a 500mA LDO (powered off Vin) near the controller ports to power them, along with level shifting bits and the requisite TVS gubbins.
