No Way Know How

 Setting up retropie for my square monitor. Problems: - flashing screen on both batocera and rteropie images. solved by editing `/boot/config.txt` to include `hdmi_group=2 hdmi_mode=9`  - add pico-8. needed to add the rpi version of the softwaree then update `/etc/emulationstation/es_systems.txt` with the following:  <system>     <name>pico8</name>     <fullname>PICO-8</fullname>     <path>/home/pi/pico-8</path>     <extension>.sh .SH</extension>     <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 "/home/pi/pico-8/pico8 -draw_rect 0,0,800,600 -splore "</command>     <platform>pico8</platform>     <theme>pico8</theme>   </system> getting to `-draw_rect 0,0,800,600` took a bit of trial and error and I'm still not sure it's right because the monitor is 1:1 so why would it be that? but looks fullscreen now at least.

  netstat -ano | findstr :8080 (the port number) This should give you the process to kill. You can then run: taskkill /F /PID 12017(or whatever the process ID is)

  xdg-mime default nautilus.desktop inode/directory This sets nautilus as the default app for opening directories instead of vs code. I actually set  xdg-mime default nemo.desktop inode/directory I'm guessing at some point I'll want to refer back to this because vs code will try to open some other thing I don't want it to 🙄

 Have had lagging and freezing since switching to Manjaro. Turns out I don't have a swap partition - how could that have happened?!  I've added a swapfile since I don't want to mess around with my partitions https://wiki.manjaro.org/index.php?title=Swap#Using_a_Swapfile
