Hey, so I'm looking to buy a ntsc nes (speed reason) but I'm living in Europe. I can't seem to find any information on the internet if there's something I should do to hookup it. I think there's a Voltage problem but I'm not sure. Can I get any help ? Thanks

In addition to an NTSC NES you'll need an NTSC TV, or at least some way to convert your PAL TV, if such a thing exists. As well as some way to get an NTSC power outlet.

I have friends that run PAL stuff (cause its faster lol) and I think they dropped about 300 USD for their setups
