Watch the Game in Your Terminal

Yes, the terminal can show the game that contains the terminal. Please resist putting that terminal on a screen inside the game unless you have made peace with recursion.

Quick start

echo 1 > /sim/display/enabled
cat /sim/display/stream

Press Ctrl-C to stop reading, then turn capture back off:

echo 0 > /sim/display/enabled

The stream is already encoded as in-place Kitty graphics commands. A compatible purrTTY or Kitty terminal paints each frame; cat does not decode pixels itself.

Tune it live

echo 24  > /sim/display/fps
echo 640 > /sim/display/width
echo 360 > /sim/display/height
cat /sim/display/format

Capture is demand-paced. It costs nothing while disabled and only produces frames while a reader is present.

What is in the picture

The capture is KSA’s clean, pre-composite scene. Game UI is not included. The default rgba-zlib encoding needs the current purrTTY native build.

Validation status

The stream works in the informal in-game pass. Its formal performance and stability checklist is still open.
