Hacking saves for GTA:SA is it little harder than hacking Megadrive savestates as the information isn't always stored in the same place depending on which point in the game you save. Not only that but you need to be able to get the save file on and off your memory card! To do this I use the Memor32 USB Memory Card.Until I figure out where/how information is saved at certain points in the game the addresses given should be used as rough guides to help you.
To hopefully make things a little easier all this information is taken from editing a save created at the earliest point in the game possible.
Data is stored little endian style so 12345678 would be stored as 78563412. The information on this page is given as it should be entered.
