Try the old F4 key trick: press F4 once before loading or saving game on the memory card and once after the loading of saving operation.
What controller do you have? my memory card problems vanished the day I replaced my Microsoft Gamepad with a Playstation controller and an PSX to USB controller adapter.
I hope this helps
GT2 works perfectly for me now
