Ok I got some information.
It seems the KI-specifically-made-Aracade Emulator is named U64Emu, and there is also U64Emu2, which is made towards KI2.
I took a moment to open my P2P program, and I think I've found just a few files which I think contain the KI and/or KI2 Arcade files needed to run them via Emulators. The files are about 300 MB, which is a good sign, since the N64 version is no more than 10 MB (I think) and the SNES verision is about 1.5 MB.
I'll post later if I got other news/information on this, in case anyone else here would be interested to know and see if there is a true way to make it so it's possible to play the Arcade version of KI and/or KI2 at home.
Thanks again for your help dude.
