This is a very simple GUI example for ATARI 2600 console. There is source code attached if you want to try to develop it. Developed in BATARI BASIC.

Thank you for your advice, usually i put the old 8 bit games or programs inside internet archive play in the browser but i forgot it.
Have a look now there is a link in the page of the games that connect to play in the browser in internet archive, the controls are a little differente because the emulator is not Stella.
If you have other questions i'm here!
Bye
Matteo
