when you open the .cdi file in discjuggler it will tell you how large it is in minutes if it is within th 70min range then it should be ok but if not then 80min ones will have to do,
i have always used the 80 min 700mb disc size for all the games except for the utopia disc and others like slave zero or something which are only 200-300mb
