I've recently bought a Nintendo 2DS and I wanted to get the handheld version of Spyro's Adventure(just the game). But, I need to if the Wii portal works on the 3DS games.
^ Actually, it uses InfaRed. You will need a 3DS Portal. Alternatively, you can also use the redesigned 3DS Portal from SWAP Force with both older games(though I'm not sure if you can use a Giants or SA 3DS Portal with SF, I've heard not, but haven't tested).
