Answer 1

Step 1: Check your firmware to see if it is downgradeable (3.03 and below)

Step 2: Downgrade your PSP to version 1.50 and hope you don't bricked your PSP (turning it completely useless) in the process.

Step 3: Decide whether you want to:

A: Keep it at version 1.50: Download and install Dev Hook and software to run the CSO

B: Upgrade to custom firmware (3.03 OE-c and etc) and hope you don't brick you PSP in the process.

Step 4: Put the CSO file in appropriate folder and enjoy

If you have a PSP already hacked, skip to step 4. Also, if you still confused, don't bother, you will brick your PSP.
