So after MUCH!!!! trial and error i finally got this bastard to work, thanks you BiTGoD
So by now eveyone knows than games that need to install data on your hard drive usually gives you the old "Data corrupt" error when you try to launch it Sooo when youre editing those eboot's and making those pkg's, you need to change the gameID to something else (eg. BLUSxxxxxx to BLUBxxxxxx) but this only worked with a few games..everybody caught up? good!
Now this only worked with a few games according to some users, but NOOOO Split Second couldnt be that easy..dam bastard.
Here begins the fun part. i'll walk you through it:
1: When editing the eboot, i changed dev_bdvd/PS3_GAME/USRDIR to dev_hdd0/game/BLUB30300/USRDIR (note there are other dev_bdvd i didnt touch those), Edit param.sfo to say BLUB30300 else your package wont compile.
2: Now after i was done making my pkg, using my new custom GameID [BLUB30300] i installed it, then i ftp'ed into the ps3 to find my BLUB30300 folder
3: The important part, once youre in the folder on the ps3, find the param.sfo file, copy it to youre pc, edit the TITLE ID to say BLUS30300 cuz remember before we made our pkg we had to change it to BLUB30300, transfer it back to the ps3, overwriting the other one
4: Dump all the game files from USRDIR of your "backedup game" to BLUB30300, because again remember thats the path we specified in step 1.
5: Run the game, when it launches it will ask to install game data, after that you can play
Now it may not work the first time, you may get the corrupt error, it worked on my second time, takes a while for the ps3 to see the new param file i guess. (Note when the game data is installed it will create a new folder named BLUS30300)
Now online you say? well i have no idea if this actually works, pretty sure it doesnt but here me out,
When you launch the game and it asks to update, i did the update, then i launch the game again and it asked to update again, so i decided to ftp back in and change Both BLUB... and BLUS.. param.sfo files to Version and App Version: 1.04, just copy them to your pc, make the change copy them back.
Now i can go online, but when i enter the lobby nobody is there but the option to invite people is, but i can't test inviting someone since i don't know anyone with the game
Thanks agian to BioTGoD for the param trick, was about looney , hope this helps guys, now i'm off to test COD BOPS or GT5 ugh long night
Follow this guide to make pkg's, its actually really simple
