Here is my Midnite PCF (black ground with lite colored buttons) for the Pronto 3000. The buttons are all original (except for a couple that I borrowed elsewhere). All the buttons have been tweaked for display on the remote. It has several wait pages for when a long macro plays. All devices have discrete power on and off. I have duplicated the cursor buttons on a lot of the screens because the wife has trouble pushing the "Hard" buttons with her arthritus.
This is a Word document that goes into great detail on how I make a bitmap button for the Pronto 3000. It has a lot of screen shots provided (a picture is worth a 1000 words). It tells what programs I use and where you can get them.
