I've recently decided to pick up an XEGS, and have one secured. I was wondering, though, I won't be getting the keyboard, are there any 400/800/XL games that would require it to start? I know there's a start button, and that advertising compatibility with these games even on the basic set would've been somewhat of a lie if one couldn't start them with only it, but wanted to check. In particular, the games I plan on getting are Donkey Kong, Donkey Kong Jr, Dig Dug, Ms. Pac-Man, Moon Patrol, for now.
Also, does it work with standard 2600 controllers? Like the keyboard, just wanted to check.
