Thinking about it a bit more it could be like the PICO-8 mentioned elsewhere ITT but instead of a PNG the QR fantasy console would work by loading programs from QR and initializing the display with the QR visual itself and then the code from the QR is exectuted and is able to access the “video memory” to read in the starting state and then you can play a game where you consume the QR visuals for example with snake. Probably needs to make the snake colored so that you can tell eatable QR visuals apart from your snake. Other games include Breakout and perhaps Pong. Frogger. Etc etc
