The dev has released a Prometheus ISO loader that works with the recently released 6.20 TN-A HEN from Total_Noob. As the name says, this will let you copy and play backups. And yes, that means you can use this to one up the official releases and play Kingdom Hearts: Birth By Sleep on a PSP Go!
Here are the instructions to run the loader from wololo, who was asked by Liquidzigon to release it:
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.
