I know this is old, but I wanted to say the 2 Amp supply will work fine. The console will only draw the power (Amps) it needs. Amp rating on a power supply is just the maximum it will output. The main thing is to make sure the positive and negatives on the barrel connector are correct. Some have positive on the inside of the barrel and for some it's negative with positive on the outside. If you buy a regulated supply, be careful. Some of the cheaper ones are noisy and it can affect your video signal on some consoles.
