Is there a safe way to edit your save files on mobile devices?

I play a lot of Gran Turismo on PPSSPP but i am kinda meh in it, which means that i struggle to win races, making me not gain as much money as i would by winning. Is there a any way to save edit? If not, then do you know any kind of money glitches for Gran Turismo on PPSSPP?
