In KI's attract movies, they actually advertised it as running on the same hardware as what was then called the "Ultra 64" (a name they dropped because of fear of a potential copyright conflict with Konami, which had created a shell company called "Ultra Games" to sidestep Nintendo of America's limits on the number of games they could release every year). The game was made using Silicon Graphics workstations, and SGI was one of the main designers of the N64 hardware, but it was still a bit misleading of them. Cruis'n USA was a better representation of what the N64's graphics would actually look like. I believe they were originally planning to release it as a launch title for the Ultra 64/N64 when they wanted to release it in 1995 alongside the PS1 and Saturn, but the N64 got pushed back another year so they made a SNES version to try to tide people over and convince them to wait another year instead of buying a PS1. When the N64 did launch, they ported KI2 instead.
