Can someone explain to me why does the game flips out on a NTSC NES??
Because of the region lockout most likely. The game was never released in the states. If you have a toaster that hasn't been modified at all, it's going to do that.

Here you go, I made this guide; it should help you.
Otherwise, buy a NES-101 Toploader, they work with all games... except Famicom unless you have a pin converter.
