When I've asked in the past the answer has been that all the games are dumped from the Fore series. Of course that just means one revision of each of the years. I can't keep up with them beyond that until they are added to mame, don't even have the dumps. The games aren't hard to get and I know a couple of people who have some of them and a box of discs but I can't see most people moving their ass on stuff like this until there is a driver.
