i did play the old GTA games a lot a while back on my old tv with the PS2, but when i got a new HD tv, i found it slightly difficult to play as the visuals where a little messed up. It's not the TV or the PS2's fault, it's just an old game going from an old small TV which was like 20 years old to a new TV that is 40+ inch HD.
I did download SA on PS store, but the controls are slightly sensative, quick unlike the old PS2 controller. So i find it difficult to move around and do certain missions. GTA VC is no longer on PS store anymore :(
also my old PS2 memory card is dying, so all my old saved game files wont really be avaliable for very long :(
