Well here's prolly all you need to know, though I may be missing something:
Best video connection possible:
S-video (if in america)
RGB (if in Europe)
Only buy the official expansion pack and remember to buy a N64 that has a jumper pak or a expansion pack in it. (may need verification)
Make sure to get an extra controller or two as the analog stick seems to get messed after a bit of play (may need verification).
Modding an American N64 to play Japanese N64 games is really easy, just get rid of the tabs inside the cartridge slot. This can be done with clippers or you can melt it with a soldering iron (just make sure not to breath in the fumes!). You may have to open it depending on how you want to get rid of them.
Reccomended games that are easy to find (tho if I'm wrong on a few, plz correct me):
Super Mario 64
Super Mario Kart
Legend of Zelda: Ocarina of Time
Mario Tennis
Rogue Squadron
Turok
Reccomended games that may not be easy to find (tho, again, if I'm wrong, plz correct me):
Conker's Bad Fur Day
Star Fox 64
Kirby and the Crystal Shards
Glover
(You could include those mosdt underrated N64 games or w/e the contest was for...)
That's about all I can think of, hope that helps
