just my opinion but you really shouldn't buy those disks off ebay. who do you think your money goes to when you buy one? (usually some slacker scrounger work shy doely living with their parents getting paid for someone elses hard work). It certainly doesn't go to the good people here at fruit-emu for the upkeep of the site or to designers and all the others involved who spend a considerable amount of their time so that you can play these fruit machines on your pc.
seems to me like there are too many laws concerning who's allowed to operate them and where they can be sited but not enough regulating the way the machines actually play
