it all depends on the game. I've seen them from 80megs (think that was talkman travel) to 1.5gigs(crisis core). one thing you can do to make them smaller is to use UMDGen v4.00 open up the iso and remove the update file... if you're on cfw (you should be, cause if you're running iso's on ofw some people will want to talk to you.) you want need or want the update files from the game anyways so it's just dead fucking space. You can also change the pic1... etc files and make it look unique to your psp. then go ahead and save it as a cso. my crisis core is just under 1 gig, and the new game silverfall is just over 200 megs for me. think its like 220.
