I want to start speedrunning but categories need to be divided into difficult, hardcore or normal should be the standard for speedrunning.

So I'm already on my first run of game, first one was normal playthrough and get 100%, then I got gold medals on every mission, how I'm playing no HUD, dead eye, reticle and auto-aim. After that I should naturally consider speed-running, but the game doesn't grace itself to speedrunners with it being dialogue heavy and unskippable distances

I've been itching to play sm64 again having played it on my Dad's N64 as a kid and beating it on the DS version, but I'm in the UK and I've read about how it is up to 20% slower on the Pal version. So I've been researching how to buy an NTSC N64 which seems simple enough as there are some for sale on Ebay with shipping should come to around £50-70. But what do I need to get it to work on my PAL TV. I don't want to get CRT TV, they take up too much room. I have a 19inch Bush lcd TV that I think would be fine as it plays old games of the Gamecube, and only supports up to 720p. What adapter do I need to convert my NTSC N64 to the US. It seems easier to get an NTSC N64 than get a PAL n64 and then buy a passport, correct?

Also, how about the controller, ideally I'd like to use a traditional N64 controller because that's how the game was meant to be played but if it puts me at a competitive disadvantage I'll look into buying a modded one.

For anyone who has an NTSC setup in the UK, your advice would be helpful.
