Here it a save game with almost 9999 bullets and 9999 retries.
The save point start from the point when you reach the shopping centre with the child.
If I tried to mod the save when the game starts it works but it reset the ammo to 0 on the save point,
I guess because you are not yet supposed to have any ammo.
So enjoy the game
