Open the ISO in UMDGen, Move to the UMD Properties Tab,and click on "optimize" to remove excess padding, resize dummy data and dummy 'update' folder contents.




Delete BOOT.BIN in SYSDIR. It's not needed unless you're a developer and sometimes it can reduce the size of the ISO significantly.




You can also "relink" pmf files to make the iso/cso smaller.

I'll use this Kingdom Of Paradise ISO an an example:






OP_00.pmf is more than likely the opening cinematic. Right click on it and highlight File Relinker and click on "Use Selected File as Source":





Then right click and highlight the rest of the pmf files in the window, click on
File Relinker and click on

Relink To '\PSP_GAME\USDIR\mdata\usa\OP_00.pmf'




After relinking, optimizing, etc. Save as ISO/CSO.


When the game plays one of the .pmf cut scenes, it will be re-directed to the opening movie. (OP_00.pmf)


You don't have to relink all of them.

With certain games, relinking all pmf files would take away from the story line of the game.

Some ISO have foreign language folders or files, which can be removed as well.

Some ISO have one big file, so you won't be able to reduce the size of the ISO just using UMDGen.

Other games have LBA protecton, which will require following a different procedure to rip the ISO.

I have the ISO of my UMD I can't get it to show up what am I doing wrong? I have 5.0M33 installed , ISO UMD MODE set to Sony NP9660 , USB DEVICE Memory Stick I'm placing the file in a folder I created under PSP/ms0/ISO I've tried different locations with no luck also can the KXploit patcher and M33 install files be deleted once 5.0M33 is already installed? Thank to anyone who can help

Hold on, what game is it and did you say you put a folder called ms0 inside the folder called psp? If so, you're going in the noob hall of fame (not an offensive thing by the way).
