I would ask Dean. He can answer any question you may have about Turbo Grafx, if it can be answered. He is A+ seller/modder. I have bought many, many, turbo grafx games from him. Literally thousands of dollars of rare English games. He never ripped me off. And all my stuff was always packaged very well. Sometimes it arrived so fast I was amazed. Like literally 1 day. The region mod he put on my duo looked like it was installed in the factory when NEC made the duo. His site is just someting he does on the side. I doubt it gets many hits, so it's rarely updated.
