Got the Gameshark 2 for the PS2, the one made back in 2006.

Selecting the codes that're already on the disc is easy enough, but it says I can update the list and add new codes for new games.

The question is, how do I do that?

I've been reading the manual (had to download the PDF for it from the site), and it seems I need a USB drive to download the codes from the site, and then I use the Gameshark to transfer said data to my memory card, and then I have to add the codes into the menu, by typing in the respective data, in order to make use of the data I put on the memory card, that I downloaded from the site...?

Either that, or I can connect to the site via my PS2 by hooking it up to a broadband internet connection?

...do I...have that all correct?

Is there anyone who can explain this better?

...

Damn, imagine if the PS2 just had a hard drive I could download the codes to, how much simpler that'd be...
