Dolphin, the GameCube and Wii emulator - Forums

Personally, I own dolphin emulator, but I don't know a good legit site to get my games(which are super monkey ball 1, 2, Banana Blitz, NSMBWii, Super Mario Sunshine, MKWii, and MKDD), what do you think is a good site for getting ROMS for dolphin?

The only legit sites for getting games are the ones where you buy physical copies. (And for a select few games, the Wii U eShop.)
