If you do, you can reprogram the console at any time, especially whenever we make updates to the code across years of the program! This will allow you to add new games to the console, tune the performance, and customize the display however you would like! Feature requests are always welcome if you would like to reach out to us as well. The below guide can be followed to program your take home consoles!<\/p>\n\n\n\n<div class=\"retro-console-guide-container\">\n  <!-- SCOPED STYLING FOR PREMIUM EYE-FRIENDLY DARK THEME -->\n
