Some consoles like the my NTSC backwards compatible PS3 have a universal power supply so that is easy. I know the Dreamcast either needs a step up/down convertor or I can swap out the internal power supply to a PAL unit. What about the following consoles though:
3DO, I have read that it does not contain a universal power supply so a swap out or step up/down convertor would be needed?
N64, I'm pretty sure I can just use a PAL power brick that connects up to the rear of the console?
SNES?
Genesis?
Original Xbox? Bit hard to find info on this one due to search engines confusing all the xbox consoles for one another
Jaguar? I've read that I can use a power adapter as long as it has these specs:
1. 9 volt direct current (DC)
2. 1.2 amps
3. Center pin negative
Any help would be very much appreciated!
