http://www.game-shoppe.com/NeoGeoCD/ A project to convert MVS games to CD format. This free game is just to prove it can be done, and is different to the actual CD version. The PCM files are different size, and there are a small number of differences in the PRG files. Very interesting to see what else this guy can manage. It's a shame this can't be done officially as the NeoGeoCD is a nice machine.
Ooooh that's pretty damn cool - last time I checked, they were doing it the other way around - converting CD-exclusive games to AES
