So, here is my first draft of first control panel. Be brutal.
One problem I have with designing these things is that I tend to want my design to be symetrical. Thus, I have put two 4-way sticks onto the control panel above and to the left of the regular joysticks. I even toyed with the idea of putting two spinners on the control panel, one for each player. I will probably backtrack a bit on this and just stick with one 4-way joystick mounted near the top of the control panel like most everyone else has done.
The group of two buttons on the left of the panel is the 1-player coin and start buttons, the group to the far right is for the second player. The other group of two buttons are the admin buttons, one will be a shift button and the other will be a pause button. Shift + pause will exit, Shift + P1 start will reset. Those are all the admin buttons I planned for.
Well anyways here it is.
