hey man, after hours spent trying to find the right solution for this issue, I just found out that the folder structure has to be exactly like this
Game Title.ps3
PS3_GAME
USRDIR
EBOOT.BIN
I just moved all the PS3_GAME folders right under the Game Title.ps3 (some games have dlc, updates, etc inside the Game Title.ps3 folder, so just need to make sure the location is right). If by any chance a game does not have the EBOOT.BIN file, just copy it from another working game. Hope this works on yours too and hopes it’s not too late. Cheers
