125w ago - This weekend Liquidzigong has released what he calls Prometheus iSO Loader 6.20 TN-A for the PSP handheld. I have not tested this (as I have 5.00m33-6), but I thought it was worth sharing on here.
Great to see newer FW being able to run ISOs, and to know that the PSP hacking scene is not dead.
To quote: So there you are, Kindgdom Hearts running for the first time on a psp go (that’s right, if you have TN Hen and this loader, you can run MORE games than on an official console), and another video showing Monster Hunter Portable 3 running on a 6.20 PSP Go... enjoy
How to install/Run
Put your ISO files in the ISO folder of your memory stick. Unzip the archive in your PSP/GAME folder. Run as any normal homebrew. For TN Hen users, you of course need to run the Hen before that.
If you want to use the M33 driver, you need a copy of isofs_500.prx which is not included in this package. You can get this file from the official firmware, by using PSARDumper

Shortly after the PS3 was hacked to allow custom firmware to be installed. Noted PSP hacker Liquidzigong has been able to add an ISO loader to the previously download-only PSP Go. This will allow users to play UMD only games that were previously unavailable on the PSP Go.
UPDATE: I redid the whole process again ... (and again) ... and somehow it now works! So I can give this an official "CONFIRMED WORKING" stamp of approval. Great work to all involved and thanks a lot!!!
If this is done correctly, the system software under system information reads 6.31 PRO and when you switch off the PSP and switch on again, you don't have to go through the whole process again - the HEN is still enabled.
Thanks BOSS. I tested on a PSP 2000 with FW 6.31. Without the HEN installed I can use the Minna No Sukkiri exploit to access and use homebrew. After replacing the EBOOT.PBP of HBL in the HBL/MENU/ directory, the PSP hangs for a short while before switching off (crashing I presume). I tried both HEN6_31 (first attempt) and then, just for good measure also HEN6_35. Same result with both HEN's.
So I am stuck here. I know Jes03 was also on FW 6.31 so perhaps he can test and assist me if he gets it right (or anyone else).
