HOW TO PLAY GAMES THAT REQUIRE 5.55, 6.00 & 6.10 OFFICIAL FIRMWARE ON CUSTOM FIRMWARE

What you need (UPDATED October 10th):



- A PSP Running Custom Firmware. Any Custom Firmware , but 5.00 M33 and 5.50 GEN are preferred, or 5.03 GEN-A if you're running a 3000 or TA-88v3. Older CFW may work, but are untested.

- The UMD of the Game you intend to play.

- UMDGen 4.00.

- Game Decrypter Homebrew (currently version 4).



How To:



1) Ensure you are running Custom firmware.5.00 M33, 5.50 GEN or 5.03 GEN preferred, but others may work.

2) Copy the ISO of the UMD in your Drive using the built in program in GEN. Just press Select whilst on the XMB (Main PSP Menu). In the menu that pops up, scroll down to USB Device. Toggle that to 'UMD Disc'. Now connect your PSP to the PC in USB mode. The PC should detect the drive, and instead of seeing the Memory stick contents as usual, you'll see a single file called 'UMD9660.ISO'. Copy it to somewhere you remember on your PC.

3) Download UMDGen Here.

4) Once extracted, run the program. Select Open, and choose the ISO you just extracted.

5) Choose "Extract image" and select a folder where you want to decompress the ISO.

6) Once done, browse to this directory in Windows.

7) Go to the folder pspgame / SYSDIR and in this folder, you will find the file EBOOT.BIN.

8) Right click on it, and select CUT.

9) Connect your PSP in USB mode, head to the ROOT of your memory stick (The first you see) and paste the file EBOOT.BIN in there.

10)Download Version 4 of the Decryptor HERE (Attached ZIP file).

11) Extract the ZIP file to somewhere on your PC.

12) Find the folder 'GameZDecryptZ' in the archive, and put that inside the PSP/GAME folder of your memory stick. So you should see X:/PSP/GAME/GameZDecryptZ/EBOOT.PBP

13) Exit USB Mode. Go to the GAME section of your PSP, onto the memory stick and find the app GAME DECRYPT Yoshihiro. Press 'X' to run it.

14) The program will do it's job, then return to the XMB.

15) Again connect your PSP to your PC in USB mode. Look in the root of your memory stick and you'll find a new folder called "decryptor".

16) Open it, and you'll find an EBOOT.BIN file, cut it to your clipboard.

17) Back on your PC, go back to the folder you originally removed the file from in step 7. Paste the new file back into there.

18) Click twice on the "parent folder" of your window, so as to return the folder that contains the folders"PSP GAME" and the file "UMD_DATA"

19) Restart UMDGen. Now, Drag and drop the PSP GAME and UMD_DATA file into the main window.

20) Click the 'Save' button, and choose where to save your modified ISO. For best results don't compress, save as an uncompressed ISO.

21) Now simply copy the ISO to the ISO folder on the root of your memory stick as usual in USB mode.

22) run the game and enjoy!

Note: Games asking for the LBA (Logical Block Addressing) require a further operation to run. With the original unmodified ISO open in UMDGen, do File -> File List -> Export and save the list. Patch your game, and just before saving the final ISO, do File -> File List -> Import, find the saved list from before, and load. This will provide the ISO files from your order, and the games work.



Compatibility List



With version four of the decrypter, there should no longer be ANY incompatibiles. All games should run on firmwares 5.00 M33, 5.03 GEN and 5.50 GEN. Older firmwares may also be compatible, but are not tested.



If anyone should find an incompatible game, please post.
