If you want to play N64 games in an arcade cabinet, the easier proven path is "JAMMA-fying" a retail N64. This is something that has been done since the 90s, check out this thread

One of the first reasons I got my eye on the Aleck64 was to play Mario Kart 64 on "arcade hardware", but then I realized at least for MK64 it would require rom hacking and a building a custom cartridge.... and so I just ended up jammafying a n64 and it works great.
