The learning curve is moderate but manageable.
If you want a "set it and forget it" experience, download the Brewology Complete Database (approx. 3,500 games). It covers 99% of US and EU PSP titles. For JRPG fans, search for the "Nippon Ichi Complete DB" which adds cheats for Disgaea, Z.H.P., and Crimson Gem Saga.
For games not covered by standard databases (e.g., recent fan-translated titles), you can create your own entries: Download Cwcheat Database For Psp
You have downloaded the cheat.db file. Now, how do you get it onto your PSP?

Cwcheat is a homebrew plugin for the Sony PSP that allows you to use "cheat codes" (similar to GameShark or Action Replay). The Database is a massive text file (usually named cheat.db) that contains thousands of pre-written codes for almost every PSP game released.
It works by hooking into the PSP’s memory and allowing users to manipulate values (like Infinite Health, Ammo, or unlocking characters) in real-time. _G Game Name [ULUS-12345] _C0 Infinite Health _L
If you cannot find a ready-to-download database for a niche Japanese import game, you can manually add cheats:
_G Game Name [ULUS-12345]
_C0 Infinite Health
_L 0x20000000 0x00000000
Open the PSP drive and navigate to:
/seplugins/
If this folder does not exist, you have not installed CWCheat correctly. Stop here and install the plugin first.
