I would like to shrink a few of my ISO's by removing the videos and maybe the sound. Im not sure where to locate these files so where i usually look is in PSP_GAME/USRDIR/some random folder? then i dummy files by right clicking and selecting "dummy" using UMDGEN v4.00. Then i would save it as a .cso and put it on my memory stick. When i try i play the game it either doesn't show up or goes to the black screen of death. Games that i have tried have been The Warriors, Ratchet and Clank, NFS Carbon, Monster Hunter Freedom and a few others. I have tryed some ripkits but hey wont work because these iso's are downloaded and have already been tampered with. So if anyone can explain to me how to remove the videos and sound to shrink my games it would be appreciated. And also i would like to know what relinking does and means?
