This guy has given us quite a few clues how to replicate this... He used his NBA Live 08' Disk dump, and places all the information from Assassin's Creed: Bloodlines into this directory.
He probably then copied the param.sfo from PSP Mini game, and modified the tag to BD-GAME instead of PSN-GAME, then placed all that information in hdd0/Game/XYZ (same as param.sfo and the actual PSP game), then copied that same information to external USB under /gamez/. Backup launcher is then launched, and viola! I can test tomorrow, got work here soon...but its really not that unconceivable that the Sony PSP emulator actually works...
