 Please note that with some configurations (for example, composite video) this can lead to not getting video output at all. If that happens, you can delete the row ```dtoverlay=vc4-kms-v3d``` in bottom of /boot/config.txt.

 Further performance improvement can be achieved by not using X11 and running the program directly in framebuffer console, but this might require doing a custom build of SDL.

+### Bonus: quickly install m8c locally with nix

+``` sh

+nix-env -iA m8c-stable -f https://github.com/laamaa/m8c/archive/refs/heads/main.tar.gz

+#

+# 1. NEW VERSION:

+# After the new version is tagged and pushed, update the `version` var to the

+# proper value and update the hash. You can use the following command to find

+# out the sha256, for example, with version 1.0.3:

+# `nix-prefetch-github --rev v1.0.3 laamaa m8c`

+#

+# 2. NEW DEPENDENCIES:

+# Make sure new dependencies are added. Runtime deps go to buildInputs and

+# compile-time deps go to nativeBuildInputs. Use the nixpkgs manual for help
