PS2 game cheats

Hello I am new to this forum.
How to download UK Playstation 2 game cheats from the internet to pc without having to connect the ps2 console to the PC? Can you transfer ps2 game cheats from pc to ps2 memory cards or use software to convert the downloaded ps2 game cheat files to ps2 memory card formats? Can you do this without having to use a mod chip, or without having to pay a lot of money to do this?
Thankyou for the advice,
