As I could see, you have a DreamCast. I don't agree with their cost structure, but I think it's a great idea regardless. Although I can't speak for Sam Pettus, I understand his motives for wanting to make a break from the scene. Web hosting doesn't come cheap, and they have to pay for it somehow. Emulation has come a LONG way in the last couple of years.
Emulators exist for almost every game system and home computer, leaving very few systems unemulated.
The two systems that I'd most like to see emulated are the Sega CD and the Atari Jaguar. Capcom CPS2 emulation would be nice as well, but it's a pipe dream until the encryption can be cracked. There's no denying that it's very cool to have a complete collection of every game released for a particular system. The piracy aspect is unfortunate, as emulation can be a very positive thing, allowing people to relive memories of classic games or even play rare games for the first time. Instead of visiting endless flea markets and swap meets looking for classic games, they can now be downloaded for free over the Internet.
