Glad to see I'm not the only one who has this cool device! Link Removed has many saves including GTA3. If it turns out that one isn't complete lmk and I'll email you a copy of my save.
Also grab the 100% GT3 save, simply a must-have if you don't plan on completing those endurance races anytime soon. GT3 feels like a whole new game with all cars released and 10 Jillion dollars.
I just found out that the ONLY game this thing is not compatible with is GTA3- ARGHHH! and I lost the good save I did have, oh well.
The Sharkport is a small little device that hooks up to your pc and PS2 via USB cables and using software on your PS2 and PC you can transfer save files back and forth. If you have a GAMESHARK you can transfer cheat codes to and from taht device. If you have ALOT of games and few memory cards you can actually store all your saves on your PC and have back-ups. Just don't try it with Grand theft auto 3.
