( I've checked the soldering several times over, and I don't think it's causing the problem - if this turns out to be the case, however, which components would be best to check out first? )
zhazam, the Diecimila with a 328 chip works great with the Video Game Shield. I have one just like that, so it isn't anything with the power. One possibility is that you soldered the LED backwards--it happens to all of us. If you did this, the shield would still work, but the LED wouldn't until you turned it around. Does the LED have a flat edge?
Does the standard arduino blink sketch blink the LED on the Arduino board?
Secondly, do you have a multimeter? Check to make sure that your arduino is making 5V on the 5V line. Also, unplug the Video Game Shield, and check the resistance between power and ground on the shield.
