Nice one thanks although it's a shame the manufacturer couldn't just say that in the first place. Being deliberately obtuse about a product is never a good sign.
No N64 isn't an issue, none of these devices can do N64 to a playable standard (the GCW Zero dropping 2/3 of the frames in Mario 64 isn't playable IMO) anyway so you're not exactly missing out.
