There's been a lot of discussion lately about the possibility of hibernation for the GP32. I presume this is mainly prompted by the desire to leave the machine in it's current state, particularly for gaming, without completely flattening the batteries.
My idea is nothing new - you used to be able to get large battery packs for walkmans to give you extra life.
With newly available high power D-Cells - NiMh 9000ma - it should be possible to get up to 40 hrs on your GP32. You can get a 2-Cell battery holder , with PP3 connector, from any electronic store. Get a PP3 connector lead and solder a GP32 power plug to it. The assembly, at a push, should fit into the standard GP32 case.
