Running Gran Turismo Portable on PSP 5.00 M33-6 custom firmware without using a ripkit

To make Gran Turismo Portable run on 5.00 firmware, you will need to decrypt the game’s EBOOT.BIN, patch it, and recreate the ISO or CSO file. This may sound tricky, but it is actually quite simple and easy to do.

First, you will need a copy of the original Gran Turismo Portable ISO (download it here).

Next, you will need the following tools:

• Yoshihiro’s Games Decrypter v3 (download it here)
• UMDGen v4.00 (download it here)

The following steps can be tricky, so read very well and understand to avoid confusion.

Run UMDGen and open the Gran Turismo Portable ISO. You should see something like what I have in the screenshot below.

Inside UMDGen’s Explorer tab, navigate to the GRANTURISMO / PSP_GAME / SYSDIR directory.

Inside this directory there is a file called EBOOT.BIN – right-click on it and choose Extract Selected…

Install Yoshihiro’s Games Decrypter by copying the GameZDecryptZ to the ms0:/PSP/GAME/ folder on your PSP memory stick.

Inside your PSP, run GAME DECRYPTER Yoshihiro V3 and choose to press O to decrypt and patch your EBOOT.BIN for 5.xx.

If successful, you should now have a new, patched EBOOT.BIN inside ms0:/DECRYPTOR/ of your PSP memory stick.

Go back to UMDGen and delete EBOOT.BIN by right-clicking on it and selecting Delete.

Import the patched EBOOT.BIN by right-clicking on a blank area and and going to Add -> Existing File(s)…

Save the modified ISO as new, uncompressed ISO or as a compressed CSO or DAX file.

Finally, copy the modified ISO/CSO/DAX into your PSP, start the game, and enjoy!

As proof, I have made this tiny video showing Gran Turismo Portable on my PSP running 5.00 M33-6.

Good luck!

UPDATE (10-Oct-09): For those of you who are still having problems, I have uploaded my patched EBOOT.BIN here.

UPDATE (13-Oct-09): I have uploaded a mirror of the patched EBOOT.BIN onto MediaFire.

Download that file and extract, then follow steps the remaining steps to create a patched ISO.
