PS2 Network-Transfer gamesaves / Crystal Chip

[dude2]

Hi.

I am able to link my ps2 up with my pc via a network. I was wondering if there is anyway that through the network i could access the memory card and therefore transfer game saves etc from my pc to the memory card?

If not, then i also have my ps2 fitted with a crystal chip. With the firmware + Bootmanager you are easily able to install applications etc, does this mean that somehow you can also transfer game saves to the memory card? If so, how!??
