Aleck 64 is SETA's adaptation of N64 hardware to arcade machines from 1998-2003.

Krikzz's latest OS 2.09 allows an option to disable the CRC Check, which will allow the roms to run. There are 5 games so far which have been modified to run as N64 roms:

Donchan Puzzle Hanabi de Doon!
Kuru Kuru Fever
Star Soldier Vanishing Earth Arcade
Tower&Shaft
Vivid Dolls
