I was wondering about this...

Is it possible to seperate the 3.3V ground and the 12/7.2 Volt ground?

If so, could we put 10.5+ Volts into the 3.3V+, then tie the 7.2V+ to the 3.3V ground, effectively making the N64 a 10.5 to 39.3 Volt system?

I have no idea what you just said...

I concour with HK-47.

Do you really think that changing the voltage referances will change the total voltage for it?
Anyways, from what I can tell, after seperating the grounds you'd be tieing the 3.3V ground into the 7.2V input, inputing 10.5V to the 3.3V + line, and tieing the grounds of the 7.2V and 10.5V sources together. I think it's overly complex to utilize 2 different battery voltages like that when you could use smaller battery packs to use the standard 2 voltages already neccesary.

It won't change the voltages, but it might make it work with higher batteries more efficiently then using a regulator for the 3.3V line and working in Parallel...

I never said it'd change the voltages, I said it'd change the voltage references, IE instead of having 3.3V-0V=3.3V you'd have 10.5V-7.2V=3.3V
