You must have some prior knowledge of the ps2! You need one of the following to get these on your memorycard:
A Playstation 2 with a Modchip, Swapmagic, HDLoader/HDAdvance v1/2/3.0(original discs), ActionReplay/Gameshark (original discs), or a priorly installed Exploit!
If you don't have above see if you can't find someone that does to create you your MC for you!
