So you’ve tried the version.txt hack and it didn’t turn out well (in short, it didn’t work for you). It’s admittedly a hit or miss bypass since not all games relied on checking a version.txt file to see if you were running the right firmware version. To date, the best and most reliable way to be able to play games that require OFW 5.03 to 5.50 is to upgrade to 5.50 GEN-A/5.50 GEN-B (no luck for partially hackable PSPs).

But what if you had a game that requires 5.55 or 6.00? Well, there’s this method.

Important Note: This is ONLY for PSP users who have the following custom firmware installed: 5.50 GEN-A, 5.50 GEN-B, 5.50 MHU, 5.03 GEN-A, 5.03 MHU and 5.00 M33. If you have anything below this, consider upgrading.
Update: Added Eboot Patcher for people running 5.00 M33, 5.03 GEN-A, and 5.03 MHU.

Requirements:

•A PSP with any of the following firmware installed: 5.50 GEN-A, 5.50 GEN-B, 5.50 MHU, 5.03 GEN-A, 5.03 MHU and of course 5.00 M33.
•Download: UMDGen | UMDGen
•Download : Game Decrypter v4 | Game Decrypter v4
Important Note: version 4 of Game Decrypter works well with 5.00 M33, 5.03 MHU and 5.50 MHU.

1.Open the ISO of the game you want to hack with UMDGen


2.Important: Go to File > File lists > Export and save it as game.txt.


3.Go to PSP_GAME > SYSDIR. You should see an eboot.bin file.


4.Right click on the eboot.bin file and choose Extract Selected. Place it somewhere on your PC that’s easy to remember. The desktop is good. Just don’t close UMDGen yet, you’ll still need it later


5.Extract the files for Game Decrypter to your PC. Copy the PSP folder from the extracted files right into the root of your memory stick. Note: The root of your memory stick is the actual drive your PC sees when you connect your PSP.
6.Copy the eboot.bin that you’ve extracted in step 5 to the root of your memory stick. Note: If your PSP is F:, it should appear as F:\eboot.bin
7.Disconnect your PSP from your PC and run Game Decrypter from the XMB


8.You will see the screen below. If you’re on 5.50 GEN-B2 Press X to decrypt the eboot.bin. If you’re on 5.00 M33 or 5.03 GEN_A or 5.03 MHU, press O


9.Connect your PSP to your PC again. At the root of your memory card, you should see a new folder called DECRYPTOR. Copy the eboot.bin that’s inside it to your PC.
Important Note: If you’re running 5.00 M33 or 5.03 GEN-A or 5.03 MHU, make sure to follow the steps below:

Eboot Patcher
•Download and extract the Eboot Patcher (Mirror 1).
•Start PC program Eboot Patcher (the executable is named Patch.exe)


•Clicking on Browse, select the EBOOT.bin by patch


•Click on Go! to patch the file


•On your PC, Add the newly decrypted eboot.bin into the SYSDIR folder that’s on UMDGen by right clicking on the right pane, Add > Add files.


10.On your PC, Add the newly decrypted eboot.bin into the SYSDIR folder that’s on UMDGen by right clicking on the right pane, Add > Add files.



11.Import the game.txt that you’ve extracted in step 2 via File > File List > Import.



12.Save (Rebuild) your game as CSO or ISO


13.Your game should work now.
Important: Make sure you delete the Decryptor folder on your PSP before trying to decrypt a new game.

FAQS:
Help! I’m getting just a black screen when playing a game hacked with this method. You have a game that’s not compatible with this method Either that or your missed a step. Try to look for an eboot.bin file, skip to step 9 and test it out if you want.

Is this safe? Yes. 100% Safe

Cool man, I haven't personally decrypted any games but I've been addicted to Undead Knights on 5.00 m33-6 firmware I've also tried decrypted versions of Gran Turismo and Motorstorm and they work perfect.

By the way, this should be posted in the Tutorials Sectiom, but great post.
