I made them dim because I didn't want to distract from the game. I removed the extra dimming now although they are still a bit dim.
I don't know about changing the button labels on the controller. When you click a button, such as Debug I'm literally just sending the key for debug (F3) to the emulator. It is one-way communication. I could change the image, sure but hopefully a click wasn't missed and you are stuck with the wrong display. The "Display Controls" button still works.
Perhaps I could just remove the existing labels on the gamepad and put the actual button that it is supposed to represent (instead of the keyboard key.) I'd still need to keep track of what keymapping the user has toggled.
Jubation, is there a way to communicate with CUzeBox? I don't actually other than sending keypresses and I literally just dump whatever is in the iframe with each new load (clean slate each time.)
EDIT: (Also, I replaced my controller image with your new one. Thanks!)
