There's always emulation. Also if you end up enjoying Illusion of Gaia, I'd recommend SoulBlazer.I no longer have an SNES, so that's not gonna do me much good. But this one is fun and I'm good with it.
It's a shame some games haven't come to the Wii or Wii U VC. I really wanted to play Illusions of Gaia.
If you want that style of game, with the addition of how-the-fuck-do-you-do-this puzzles, BrainLord is also interesting.
