Looks like checking the checksums is the way to go for the PS2 games, somehow I just assumed it wouldn't be that simple. I thought that dvdisaster should work for DVDs based on the name, but it gives the error "this software does not support DVD-ROM type media" for DVD games and also for regular movie DVDs. Maybe the ebuild is limited to just CDs for some reason. - Lasse
