Here's a quick preview of what the Game Selection screen currently looks like:

I still have some more work to do.

I'm thinking about adding a control explanation to the bottom of the screen. Something to indicate that moving the joystick in any direction will select a game (from any screen you can directly switch to one of four games). The game will begin if the start button or the A button is pressed. Pressing the test button will bring up the menu for testing the system hardware.

I also want to add some animation to this menu, but I'm still not really close to polishing this up-- Especially since I haven't worked through the cartridge design.

More soon. ;)
