1 -extract it and put on an Ext HDD , rename the folder to PS3_GAME / OR if you have it installed on your ps3 and you know what you're doing , navigate to your game folder(PS3/HDD/game/gameID) , copy that folder to your External HDD with multiman and proceed to the other steps.
2-open the Param.sfo with an Param.sfo editor , change the category to "DG disc game(Blueray)" and save & remplace.
3-extract the "Fix pakage" and copy the eboot.bin file
4-download true ancestor self resigner version 1.91 , paste the eboot.bin file in the same folder with the resigner ,get the game's rap file , (you can find that on psnstuff, or somewhere on the net , if you don't have it sometimes it works without it ) Now put the rap file of the game in the Raps folder (you find that in the true ancestor folder after you extract it),
5-open true ancestor , click "2" for resign to non Drm eboot , now the eboot is going be resigned , after its done put it back in the game folder where u found it ,and run the whole thing using multiman , with "external" and "Db mirror" options ticked,Now the game plays , enjoy!
P.s if you have it extracted and runing it shows a black screen then it might be an eboot issue , pm me , i will send you the eboot.bin i resigned (:
