I was looking around some forums and I found a Heavy Rain update which supposedly works, seems like great news to me, this is whats in the NFO:
Here is the repack and instructions:
- copy the two folders to your INTERNAL HDD to /dev_hdd0/vsh/task/ (replace)
(should look like this: /dev_hdd0/vsh/task/00000001)...
- reboot PS3 without jailbreak
- run the package updates that will appear under the GAME menu.
(first 1.01 then 1.02)
- reboot in jailbreak mode
- replace eboot.bin in /dev_hdd0/game/BCES00797/USRDIR/
(the updates installing a new eboot.bin)**
- play the game
The eboot.bin is the one from the bluray disc,
so this way could help for other games too. We will check it !
