I just bought a 'MultiVoltage PSU' from gbax.com as I am tired of having to replace batteries/worry about battery life in 166MHz mode. However. my question is this: I think the GP32 normally takes a 3v current (at least the port on the bottom for the PSU says '3V in', If I am wrong about this I'd love to know) but what about when I run things in 166MHz mode? Does it need a higher voltage? Please 'elp!
