I am trying to edit the config.txt file from /Users/myuser/Library/Application Support/pico-8, but it is overwritten every single time I exit out of pico-8. Does anybody know why this is?

I'm using PICO-8 v0.2.1b on OSX.

I have validated (multiple times) that pico-8 is NOT running when I edit the file. When I then start the application, the settings are still present in the config.txt (although my changes seem to be ignored) and then the file is overwritten with default values when I exit.

Thanks for any suggestions!

I just tried to reproduce this a few times, but it seems to work fine for me. I'm on an older Macbook Pro still running Mojave, so maybe it's a Catalina problem?

It did seem to ignore when I changed fullscreen_method from 0 to 2 (fullscreen), but I'm guessing that either it's not implemented yet or I have to set windowed to 0 for that to work. But other settings changes did take effect (displaying FPS, etc).

Thanks for checking that out, yeah it could very well be a Catalina problem. I'll add a report to the bugs forum.
