Hey so i bought a ps2 off creigs list...

anyways i has a HD witha bunch of games... and it loads of the memory card.
theres no mod chip and i belive its called 'key launcher'.

anyways the seller wont tell me how to do it for whatever reason so anyways
HD loader is an older version (May 2005 version) i was wondering how to update HD loader with the most recent one.. and also, cogswap and the other stuff that comes with Key Launcher dosnt work. i assume the ''programs not installed' with key luncher. but HD Loader seems to work well.

so i mean what do i have to do to update these features?
