I used OPL 0.8 to delete a game (Alien Hominid PAL if it matters) and it deleted all the entries in my ul.cfg. Not the games themselves just the contents of that file. I have no idea how to rebuild it or what information would be pertenant to this problem/bug so if there's any info I left out that would be useful please let me know.
PS2 slimline (info in sig)
150GB WD Passport
ULE 4.41a & OPL 0.8
All games except one were in ul format and installed using USBUtil v2.0 Full (English)
Well I used USBUtil to recover my list and everything is good on that side. Also, OPL did delete the game I had meant for it to delete.
