Well, i wasnt want give up to test the patch, so, after trying 1000 differents iso's and cso's, i tried my last option: i converted one iso to a signed eboot, like the psn version of final fantasy tactics.
After doing it, the patch worked and run smoothly.
I just want to inform here that i conclude that the patch DOESNT WORK on isos and cso files of the game, only on original UMD and signed eboots.
I know that it is not a priority for you right now, but it would be nice in the future you can get the patch work on isos.
great work, the game now runs nice!!! thank you.
