GTA San Andrea’s definitive gamesave switch it has two save slots the first slot is a fresh start with 99 million and weapons the second is a 100% complete with weapons. I’m working on nice city next. What I do is edit the gamesave from my ps4 version using gamesave wizard then I I dump the .sav files using save wizard then I imported them to the switch, I did a gamesave using the switch and then backed them up.
Enjoy
Do you have a save for GTA 3?
