Problem with ISO loader.

I have GTA:LCS on my memo stick but when i try to load it and play the screen goes black. Ive tried DevHook and DaxIso. Neither work. Is it because I need 2.00 FW.


B/W: I have F.W. 1.50

Enlighten me. What's FW? I'm not caught up on all the terms. :p

Make sure you have the latest version of DevHook (I think its version 52_, this will allow you to emulate FW (Firmware) 3.03

>> Download Devhook .52 + Installation instructions here <<

Sorry it took so long to reply.


I now have DevHook.52 Please tell me what devhook settings i need to use to load a Ratchet and Clank.iso.Preferably without a UMD in the drive.

Just copy the ISO to the ISO folder on your memory stick. Then turn on your PSP and the game will appear in the GAME section on the PSP. Click [X] (or [O] if your psp is japanese)) to run the game.

If the game doesnt run it maybe because it requires specific settings so try changing them on the menu when you first run DevHook. youll need to completly reboot the PSP (Take the battery out then put it back in again).

Just to be sure this is w/o a UMD right. Because when i try i select the .iso,
then i select FW 3.03,then I start dev. the only thing that changes in the game section is a Key that says [Certificate Utility]

Im not sure of the exact settings you need. If it doesnt work then maybe upgrade to a custom firmware such as 3.40OE.

with the custom fw i can do everything that i can with 1.5 right.

With the custom firmware you can run practically all the homebrew created for 1.5 with the exception of homebrew that changes fonts, sounds etc.

There are program specifically writen for the custom firmwares that allow you to change fonts, sounds etc. Using a program like this created for 1.5 on a custom firmware could brick your PSP.

But with the recovery menu built into the CF you can restore any damaged files so long as they are not vital system files.

does that include IRshell?


have you ever tried it, cause im not very smart when it comes to this so i need to know if its somewhat easy.
