Let me get this right, you need the original disc to use this?

wow just wow is all I can say if that is indeed true. You do realize that Nintendo no longer sales gamecube games so even if people do pirate them Nintendo is not losing any money and all your doing by having to use the original disc is punishing the people who really do want to play there legit backups. People may have sealed collection and don't want to open them, may have there collection in the attic, gamecube games store away and don't want to get them out just so there can spend ages making 1:1 backups and verify the game there all ready own. All I can say is I hope someone comes along and sorts out this BS (the person who does, deserves there hand shaken). What make this even more worse is I bet tueidj himself use's a version of Devolution that does not require you to have the original disc in the drive to verify the ISO (he even knows how BS it is).
