*How to make backup ISO files of YOUR PSP games and compress it to a CSO file format*

Custom search my site and other psp affiliated sites to find what you're looking for.

NOTE: This tutorial is meant for the purpose of making backup files of your psp games incase 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://rapidshare.com/files/63815646/USBSSS_100.rar.html
  2. UMDGEN v4(the compressor): http://rapidshare.com/files/63815922/UMDGen_v4.rar.html

Step 1:

First, download the 2 links above and open up the ‘USBSSS_100’ folder.

Step 2:

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:

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:

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.


If you have any problems with this just ask and I will try to fill you in and help you resolve the problem.

Hello, Can you please help me? I am stuck on step 2. I could not find MS/PSP/GAME150 folder on my PSP. I tried to make a folder PSP/GAME150 but it did not work.
Thank you Mario

Do you have a slim or phat psp?
What CFW are you on?

If you have 3.52 M33 or above then you can press the select button while at the XMB and on 'USB device' select UMD disc. Then go to USB mode and you can drag the ISO over to your computer.

Hello, I Have a Slim & Lite PSP system software: 3.71. I am a newbie to the PSP so I don't know all the lingo yet. When I open the PSP folder on my computer I get the following Files/folders: PSP, Picture, Memstick.ind, MSTK-Pro.ind. Sorry but I could not follow your directions. Do you have any other suggestions?

AdventWolf said...

Oh, your not on a custom firmware. You'll need to be on a custom firmware in order to do this, to gon on CFW you'll need to downgrade your psp by using a "Pandora's Battery and Magic Memory Stick".

i tryed to make a iso for rachet and clank size matters. but it kept saying on the pc that perameter incorrect can not continue. Am i doing something wrong???

AdventWolf said...

What CFW are you on now?
3.52 M33-4 and higher allows you to just press select or home while in the XMB.
Then go to the USB device option and select UMD and you can transfer an ISO file to your PC if you have a USB cord connected.

So are you saying that I can't do the steps above / put games on my PSP if I don't have a CFW?

How come the PSP downloading centers can put games on my PSP?

AdventWolf said...

These steps have nothing to do with downloading games to put on your psp.

These steps show you how to backup YOUR OWN GAMES and put the file on your memory stick to play.

And yes, you need Custom Firmware to do these steps because it uses a homebrew program to backup your games. Albeit this is an old method and there is a better current one.
