ISOtool for SRWZ2

People who are itching for SRWZ2 with custom firmware 6.20  or below may find themselves out of luck when trying to run the unpatched ISO.   Fortunately there are a few options available to you, and I’m going to post the one which has worked for me (I am on 5.50GenD).

Someone has specifically created an ISOTool version to patch the ISO to run on 6.20 CFW and below.

  1. Download ISOTool 1.972
  2. Copy ISOTool into the PSP/GAME folder on your PSP
  3. Copy the ISO onto the ISO folder on your PSP
  4. Run ISOTool (should be under games on your memory stick on the XMB)
  5. Select the SRWZ2 ISO and select Patch.
  6. Select Patch_Prometheus.
  7. Select the SRWZ2 folder.
  8. Once the patching process is completed, enjoy SRWZ2!
