Hmm, I'm guessing the emulator you can download from the internet like Visual Boy Advance and such, it depends on the game I guess. I've never played them before so I'm not to sure, I'll have a dig through and experimentation for you, though.
Have a favourite aspect yet? Or is it still in the making? Ah, don't worry about that, everyone goes through that. You'll get to know people once you start talking to others on threads and such, eventually friendships will be formed. :) It just takes a little time.
