If you are unfamilliar with these terminology refer to the list below:
Cwcheat----A homebrew cheat device that allows players to cheat in-game with database
.prx----A plugin module for hacked psp that have diffrent functions
Recovery menu---- the menu that appears when holding R trigger when booting psp
CFW----Abbreviation for custom firmware
DISCLAIMER: I am not responsible for people that don't follow the instructions and mess up their psp, so only do it at your own risk!!!
Step 1: Step 1
Ok the very first thing you'll have to do is download the cwcheat package and the latest DB (database)
Links are below...
CWcheat package: http://www.mediafire.com/download/6p5dymms6y669x7/CWCheatv0.2.3.zip
CWcheat db: Included in above package
After that on the psp go to SETTINGS>SYSTEM SETTINGS>SYSTEM INFORMATION and you'll see your firmware version ending with letters, WRITE THIS DOWN ON PAPER: YOU'LL NEED IT LATER!
Now plug in your psp through a usb cable or a card reader for memory stick.
Go to the root of the memory stick, there should be a folder named "SEPLUGINS". If not then make a new folder named 'SEPLUGINS'.
Step 2: Step 2
There will be a mess of files.
Heres when you'll need what you wrote down on paper earlier, if you're custom firmware version is anything OTHER THAN 3.71m33 proceed to the next step. If you're firmware version IS 3.71 m33 goto the *special* step.
step for non 3.71m33
Now look for the folder called INSTALL and open it,there should be a folder of seplugins inside.Copy and paste it on the root of you're memory stick.
*special*step for 3.71m33
Ok go to the file called INSTALL_371and open it, there should be a folder of seplugins inside.Copy and paste it on the root of you're memory stick.
You may ask what makes the INSTALL and INSTALL_371 folders so diffrent but the processes are the same, the reason is that the files are coded diffrently and DO NOT MIX THEM UP!
Step 3: Step 3
when the game has loaded, press select and hold until a menu pops up. there are several options including select cheats, enable cheats and blah blah blah... Choose select cheats and press X on the ones you want, then go back by pressing O and press X on the enable cheats option. Exit by hitting the select button and the cheats should be effective in game. Whenever you want to access the cheat menu just press and hold select.
