This has happened to me recently. All you have to do is unplug the power supply from both the Wii and the wall socket for 2-3 mintues. Plug them back in, and your Wii should work fine. You don't have to unplug everything on the console, just the power supply.

I got this info from Nintendo.com: http://www.nintendo.com/consumer/systems/wii/en_na/ts/power.jsp

I'm playing through it now for the first time, and it's great! I highly recommend it.

I like All-Stars the best.

The best one is a Model 1 Genesis that has "High Definition Graphics" written around the cartridge port. Those have the best sound. Later Model 1's that don't have that written on it and model 2's have noticably worse/distorted sound. Check this video for a demonstration.

I'd avoid the Model 3 (the smallest one) as it does not support the 32X or Sega CD units. It also does not work with some Genesis carts like Virtua Racing.

Hope this helps.

Pac-Man was one of the first video games I ever played, and I still play it often. Happy B-day, Pac-Man!
