This was hard to do. Using Reason, I exported a loop of every single note played in the song (sans repeats) to one file each, and then put them all back together using a BMS creation tool.
BMSes, for those not in the know, are simfiles for beatmania, meaning they contain the information and sounds that make up songs to be played like in beatmania. I've got a lot of official(ly illegal) ones, and a lot of originals from mildly popular Japanese composers.
So yeah, Archetype as a BMS. Download, have fun. If you don't have a beatmania sim and you want to play or just watch the notes fly by, download MixWaver][. Extract it, place the FOLDER CONTAINING the files in the Archetype zip in the same directory as mixwaver2.exe, open the program. You can either "listen" to it or "play" it.
FYI, it's got 4 difficulties: 5key (7☆), Light 7 (4☆), 7key (7☆), Another 7 (8☆).
