Step by step guide on how to setup DevHook 0.42a

Before you start make sure you have a PSP with firmware 1.50

1. Download DevHook 0.42a from here

2. Go into the MS-Root folder in the DevHook download and copy the dh and psp folder onto the root of your mem-stick

3. Download pbp unpacker from here

4. Download 2.50 update from here

5. Open the update with pbp unpacker and extract all the files to wherever you want (the file needed is the data.psar)

6. Get the data.psar from the extracted update and put that onto the root of your mem-stick

7. On the psp choose devhook installer and start that, than when you are in the eboot start the installer, at the end if you want to copy your flash1 read what is said on the screen, which should be press O to copy flash1 settings

8. When everything is done open DevHook and use these settings:
UMD Select: (choose your iso, cso or --UMD DISC--)
UMD Mount: ISO ANYUMD
UMD Version: 2.xx > 2.00
Firmware: 2.50
CPU Clock: 222MHz / 111MHz (that is what I always use no problems)
Boot Select: Reboot XMB
Remote Ctrl: Kprintf (115kbps): This is if you want to use the psp remote that came with the psp to use with music

When using ISO/cso make sure there is a UMD game in the drive, never use a UMD movie.

When selecting a UMD Disc with the UMD Select option the other settings will be changed automatically so the UMD will run, the settings can be changed back later by pressing O when DevHook is auto-starting.

When in the 2.50 xmb if you are on the umd icon if you hold down the Home button and press the L or R trigger you can go through all the ISO/cso's on your mem-stick, and in 0.42a it will tell you which game you have changed to at the bottom this saves you waiting (11 seconds) while the ISO loads up on the xmb.

9. Use the PSP ISO Compressor to compress the ISO into cso format for use with DevHook: Get it here
This is a very easy to use compression utitlity and you should be able to work out how to use the compress and decompress functions thanks to the very user friendly GUI. If you haven't worked it
out in the compression settings set the "Select compressed ISO format" to "ISO -> CSO", and I useually use level 9 compression.

Where to put your iso/cso

Some people don't know where there iso/cso/dax (dax isn't compatible with DevHook by the way) goes, it goes in a folder called ISO in the root of you mem-stick (this applies to all loaders).

Your psp isn't now a 2.50

Some people seem to think their psp is now 2.50 it is not just hold down the power button until the psp turns off completely, boot the psp back up and it will be back to 1.50. It never actually installs anything to the psp it just runs the dump from the mem-stick, if it made the psp update to 2.50 nobody would use it.

The highest firmware you can emulate with DevHook is 2.50

At the moment 2.60 and above can not be decrypted, so until they are 2.50 is the highest you can use with DevHook, I will update the guide when they are decrypted. And also you don't have to install previous versions of DevHook to get it to work because all the updates of DevHook overwrite the files from previous versions.

How to install new verions if you already have a previous version set up

Whenever you download a new version of DevHook you can insatall it without having to re-install the dump. When you have downloaded the latest version of devhook go into the MS_ROOT > PSP > GAME > and remove the DevHook installer eboots. Now go back into the MS_ROOT folder so you are just presented with the folders dh and PSP, now just copy these two folders into the root of your mem-stick and then if a message comes up saying something like "If the files in the folder have the same name do you want to replace them?" click "yes to all".
