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. ;)
