I have v1.0 on PC  
I've always modded weapons to make them cooler. I use IMG tool to change the weapons.  
I recently modded a few weapons and started up the game. When I was loading my save it froze. After reloading a lot of other times it still froze.  
I did back up gta3.img and everything. I replaced all the files with the non modded ones and reloaded my save but it didnt work still.  
So I reinstalled the game and deleted my back up and the game still doesnt work. I even tried starting a new game it still freezes.  
What patch should fix this, if there is any?
