You gotta throw a language switch on that Genesis. Some of the games do all kinds of dumb ---steaming pile of meadow muffin--- when you flip them over to JAP. Works with the 32X games, too - you just flip the switch immediately after you turn on the system to bypass the region check. I actually owned both the SegaCD and 32X while they were viable, but I paid all of $90 (IIRC) for the CD and $20 for the 32X.
My mother sold my SMS, Genesis, 32X, and Sega CD collection for $20 less than a week after I went to college. Yep. Now I don't call or visit.
