For the original versions of Metroid II and Super Metroid I'd try eBay, that's where I found them. You might find Fusion in small game stores that still have GBA games, if not, also on eBay. If you have a Wii, you can purchase a Virtual Console version of Super Metroid. If there's any Metroid you should have it's that one ;). I hope this helps.

And I recommend, for the sake of the classics, purchase the snes version, if you can find it.
