Well, Google translate BLOWS, but this is supposedly what this is supposed to be able to do.

There is a feature called "Make fake_np date File." and when you click on that, it prompts you to select a directory. The directory you select, is a directory containing an EBOOT.pbp that was purchased on the PSN. So, basically, download a DEMO from the PSN (once it is back up obviously ) and then select the "Make fake_np data File." option, and it will show you the GAME folder on your PSP. Select the folder that contains the demo game, and then hit X to start. It will extract the data inside of the PSN download and save it on your memory stick.

Next, go back to the main menu, and select an ISO file. Then select the option that says "Apply fake_np data" and, it will apply the fake data to the ISO (Time will vary depending on the size of the ISO). Now, after it finishes, I'm not too sure where to place the ISO, because with the PSN being down I can't try it for myself, but im assuming you place the ISO into a folder inside the GAME folder. It will recognize the ISO as a PSN download, as long as the PSP you are using to play it is activated under the same PSN account as your hacked PSP, and it will allow you to play the ISO on official firmware.

For obvious reasons, this hasn't really been tested too extensively yet, and when I have time to test it fully, once the PSN is back online, I will post results promptly. Download link is below:

Users who ALREADY have an OLDER version of ISOTool installed, you can update without your computer by following these steps:

1.) Open your older version of ISOTool.
2.) At the main menu, press TRIANGLE and select Update iso_tool
3.) It will prompt you to select a connection, but the connection selection screen will be in JAPANESE
4.) Find the connection you want to use, and press CIRCLE, NOT X (Japanese remember?)
5.) It will connect to the iso_tool server, and search for a newer version.
6.) Once it finds the new version, press X to install
7.) When it finishes, it will say press X to restart, press X, enjoy ISOTool v1.975

Rep + (maybe wait until I check if it works to Rep + )
