Has anyone been able to replicate the "Test" screen behavior? I have adapted the .py code @TheKitty wrote to add the finer 1 Up/Down motions (from Stack-Up) in addition to the larger 2 Up/Down motions (from Gyromite) originally in the code and R.O.B. responds to all commands perfectly, but I can't get the Test function to work as it did in the original game. I have tried what @TheKitty came up with and also the 00000 000101 1101011 11111 sequence that @ta0 determined, but they just turn the head LED solid on. However, the original Test function made the LED blink, as shown about 10 seconds into this YouTube video I found (the rest of the video isn't particularly interesting):
Did you codes the test head LED blinking into your Atari ROM @Pioneer4x4? Anyone else have any suggestions? Another question I thought of: I have always assumed Test mode was the same for Stack-Up and Gyromite but does anyone know definitively if that is true?
