Is there any way to save data from the Pico-8? I'd like to have persistent high scores in my game, but the Lua file io doesn't seem to work (either that or I'm doing something wrong).

Has anyone done this or have an example of how to do this, or is it just not possible?

It's not possible right now, but I believe it will be possible in the new version which comes out pretty soon.

Ok, cool! I can wait, I just wanted to make sure I couldn't do it right now. :)

Pretty sure that's on the table for 0.1.2
Although, it looks different than I thought it would. My assumption is that it would save it to the cart, apparently it's in seperate files.

It'd be cool if it could save into the cart, but it makes more sense to have it in separate files. It's a lot easier to implement separate files, too.
