Only reason it ran as well as it did on PSP was because the core architecture was based off the same thing iirc.Nope, dead serious. Even if it ain't good. N64 ran on PSP, DS ran on PSP, and now we have DS on 3DS via emulation. I'm sure it can be at least tried.
Seeing how PSX emulation is right now, I doubt N64's ever gonna reach a playable state on the 3DS.
