Classic NES is kinda of an weird idea, for ppl playing on a emu it is stupid cause you can play it in your regular NES emu, for ppl with flash carts, it is cheaper to use pocketNes, even if do not own a flash cart you can play it with a multiboot cable, and at last for ppl with nothing of that is some what of a ripoff cause you can unlock metroid in zero mission and they released a cart with this game and most of those games already saw revisited versions on gba and another consoles. Classic Nes stinks and i don´t like it!
