I was wondering if you could have a digital game manual in your game, similar to the paper game manuals that most NES games have.  Opening and closing the game manual would need to be a button not in the NES control scheme, so that you would still have access to the original buttons for playing the game.

I hope they are.

Thank you for the idea

Cool.

having a manual like NES games is a great idea if you have time for it. i would just make the manual a pdf file that is separate from your game. i don’t think many NES games had a manual in the game itself, but if you wanted to put it in the game you could have it accessible from the main menu and/or pause screen. i would keep it at the same resolution and use the same buttons to navigate through it though.
