Editing GTA3.IMG shouldn't affect your game, if there's any problem there the game will just crash. No experience w/
trainers but if the save game editor's like mine that shouldn't be a problem, in fact it should have a selection to reset
TIMES CHEATED to 0 & would prevent cheat traps.
Those guys usually want DATA files left out of DL'd copies.
The only useful thing I can think of is your save got corrupted, sorry I can't be more help.
Thanks. I have reinnstaled the game to a vanilla 1.01 version and it's still not working. So I guess it's a save problem. Is there any way to edit savegame so I won't need to star game all over again?
