Oh, yeah, I know it isn't pure at all, although I wasn't aware what synths he used in the album, but mainly, the point I was trying to make is that even though he limited himself throughout most of the album to "chippy"-sounding synths (gawd, that man can work a pulse wave), he managed to create an absurdly epic prog rock opera. The limitations are part of the brilliance, and they drive the innovation; that's the beauty of chiptunes in my opinion. That, and I fucking love the NES and Gameboy.
