UPDATE 3: http://www.pspx.ru/forum/showpost.php?p=1114595
im gonna test some of the games on this list to see if they work with this method
UPDATE 4: found this on pspx
The general methodology for making games work is quite simple ...
The game should have an official patch (and how else do we launch it from the internal disk?).
- The patch is unpacked, the contents of USRDIR from the patch are dropped into the game folder (with the replacement of the original files).
- PARAM.SFO (from the disk) is edited. Change the Category from DG to HG and App Version to the patch version.
- Delete the LICDIR folder if available.
- Rename PS3_GAME to the name of the PARAM.SFO game (for example: PS3_GAME in BLES00222. If the game sets the data, add GAME at the end, for example: BLES00222GAME)
- inject into backup.
- some games may require a disc (insert any) or some other manipulations (see "more" in the examples - there are not all games, but the principle should be clear)
might be able to modify this and add the license files anyway?
UPDATE 5: here is a concise video detailing (a similar) process
Update: 6am im going to bed maybe someone else can figure this out
