ROMs are NOT illegal if they are rom-hacks. I should know, I play them all the time. Also, ROMs are a fast and easy way for people who can't afford the game to play it. I don't own White 2, but I have a ROM of it. It's SO much easier than paying for the game. Plus you can't get it stolen! Its data is stored safely on the computer, ready to play at any time. It's even better if you have a Flash-Cart. then you can LOTS of ROMs!
