Search for UMDgen. You can strip out the update folder, and any .pad files to save space. If you're real good at it, you can relink music and videos to save a lot of space, but may ruin the experience of the game. Then when you're done, save as an ISO. Drag that ISO you saved into the tab where it lets you compress, and compress it.
Then you're done!
yes ive done that, removing the update folder and getting rid of the other languages, but the game size still is fairly large, not small enough to fit on my memory stick. i have seen other ripkits that say they have stripped it to about 700mb and truthfully they would be perfect if they worked!!
is it possible you can provide/make a ripkit for me as im completly useless in smaing a game smaller, all i can do is convert tho iso to cso nd remove the update and landuage folder :D
