doesnt change the directory to ms0:/file it doesnt change it to anything even when it was "../../../" i erased the line and it still saved it in ms0:/psp/game/savedata so why have the pge.dir.chdir if it doesnt even work?

The savedata itself will always be saved where it is supposed to be (in the SAVEDATA folder).

Changing the path to the EBOOT is just done in the sample because the EBOOT is not in the same directory that the script is run from.

Always assume that an error is in your own understanding or code and it'll put you on the right track. I don't mean just for PGE, but generally

[dlevans]

so lets say i wanted to run a phonebook app could i use this to save the phonebook to lets say ms0:/phonebook/phonebook.txt instead of a game save?

[InsertWittyName]

No.

You could save it using regular file io though via pge.file.
