Just make a simple menu using text, you can apply the same knowledge to bitmaps

This was made in Dark Basic Pro, it uses the function command, and text and values, it can be controlled using the Keyboard and joypad, rather than the mouse. If you want to use bitmaps, load the bitmaps before the command set and replace the text commands in the functions with paste image commands, and maybe adjust the numbers a bit depending on image size.
