I suppose it depends on what front end you're using. I'm using three areas to convey instructions to the user - the CP, the bezel and the FE. The CP can't be changed, so only the most basic info is here. In this case, the fact that pushing the 1 and 2 player start buttons together sends an "esc" command (via IPAC). The bezel can be changed fairly frequently, and that's where I'll put basic instructions on how to navigate through the FE. On the FE itself, the basic idea (push 1 player start to begin) is reinforced. I plan on also using CPViewer to give specific game control info to users via the FE.
