~Make Backup ISO Files of UMD Games Then Compress to CSO~
LOOK HERE: The cfw 3.52 and up have a built in feature of this, just stick the UMD you want to rip into your PSP and plug in the USB cord to connect your PSP to your PC. Then press the select button to bring up the vsh menu. Scroll the USB Mode option until you see 'UMD Disc'. Enter USB mode and you should be able to copy your game ISO to your PC. If you do this, rush past steps 1-3 and onto step 4.
NOTE: This tutorial is meant for the purpose of making backup files of your psp games in case if something happens to them, or to make a file to put on your PSP to play the game, to rid the need of carrying all the discs of your games. It is not meant for illegal purposes of distributing the files to others. This program requires the use of firmware 1.5.
Files You Will Need:
1. USBSSS_100(the ripper): http://www.megaupload.com/?d=SXFKAI3G
2. UMDGEN v4(the compressor): http://rapidshare.com/files/63815922/UMDGen_v4.rar.html
Step 1: (Download)
First, download the 2 links above and open up the ‘USBSSS_100’ folder.
Step 2: (Positioning the file)
Once you open ‘USBSSS_100’ go from MS_Root/PSP/Game, and you will see the two files you need. Copy and paste the ‘%__SCE__USBSSS’ and the ‘__SCE__USBSSS’ folders onto the PSP’s ‘GAME150’ folder under MS/PSP/GAME150. Then exit out of USB mode, but keep your usb cord plugged into the psp and computer.
Step 3: (Creating ISO file)
Stick which ever PSP game you want to create a backup iso file from into your PSP. Then go to the Game icon in the xmb menu (the main psp menu which includes the Video/Game/Photo/ and Music icons). Once you are in the Game icon, go to ‘Memory Stick’ and you will see the program ‘USBSSS_100’, click on that. Then the menu will pop up, click on the very first option ‘Virtual FAT16 . UMD ISO-9000’.
The PSP will then connect to your computer and a iso file will show up on your computer. Copy that iso file onto your desktop or wherever and let it copy over. On your PSP screen, there will be a % option under ‘last access’ wait for that number to go from 1% to 100% and then back down to 0%. Keep watch on your computer, it may take 15 minutes to copy the iso file from your psp to your computer.
(NOTE: This may take quite a while, do not disconnect prematurely, as your iso file will be incomplete. If your psp stays at 98 or 99% for very long, don’t worry, it stays around there for quite a while. However, if it stays on one of them for longer than 10-12 minutes, disconnect and look on your computer for the file, and then put it on your PSP in the ‘ISO’ folder in the base of your memory stick to make sure it works.)
Step 4: (Compressing to CSO format)
Once you rip the iso file, you can compress it to make it a much smaller file. The file we are looking to convert it into is a .cso. Open UMDGEN.exe and a window will pop up, there is a blank area on that window where it says “no items to show”. Drag the iso file you just made over to that section and the files will show up on that screen. Once you have the file set up in UMDGen, then click on the option ‘Save’ with the floppy disc icon. 3 options appear to save the file as: .iso file, .cso file, or .dax file. Now, we are looking at .cso file. Click on the .cso option and chose a location to put the file and let UMDGen convert the file into a cso.
Step 5:
Once the file completes converting you can put the .cso file into the ‘ISO’ folder in the base of the Memory stick. Congratulations, you have created a backup iso file of your psp game and converted it to a .cso file to reduce the size of the file.
You can also shrink the CSO further by deleting certain files such as .pad files.
You may also delete the BOOT.BIN file and the 'UPDATE' folder under
//PSP_GAME / SYSDIR
You may also see folders/files that represent different languages - EX: 'en' = English. 'fr' = French. 'gr' = German. 'jp' = Japanese. or W/e. You can delete the folders/files that represent any language other than the one you prefer.
By doing this, you can clear up an abundance of space.
