just in case anyone still own one and wants to get a little more out of it heres what you can do
there are several things you can do. And none of the require a hard drive although that is a great addition to add on to a PS2 making it more Xbox like where you can store all your games on it and increase loading times and decrease laser wear.
1. get a memory card exploit
2. get a set of swap magic discs and an after market flip top (older chunky models(shown in pic))
3. get swap magic discs and an after market flip top( like the one in the attached picture), or swap magic discs and a tool that goes by a million different names like
slim tool, ghost switch, magic switch, magic keys and so on (newer slimline models)
4. best but most expensive way is not a soft mod and that is to get a quality modchip installed.

this is a good site but a lot of the people like to play tricks on people which can completely screw up your device your attempting to mod whereas everything I post is at least 90% true and i have personally done it or have personally seen it done
