yes, i've tried alcohol with securom settings.
i just don't get it

.
when i scanned the game with clonyXXL it had 10 skulls

, and the protection was securom 4.78.
surely there must be some way of backing up roller coaster tycoon 2, with out the need of a patch?
i'll try a few more time's when i get some more disc, if no luck i'll just give up.
thanks for your help!
