Let's see I have, chipped PS1 and 2.
The PS2 I mounted 2 internal memory cards and added a switch to select witch one is active.
have a flashed 360 and have the fans running on 12 volt.
my psp is running custom firmware,
and my wii has a wiikey and HBC.
Oh and my friens has a Nyko wireless sensor bar for the wii but it ate through batteries too fast so I have it powered through USB now.
Think that is all of them.
