X Test
Test of X values from 0-159. Use the RIGHT Joystick to move 2 of the robots. If you push upward the left/right movement is slowed down to facilitate testing. (2nd joystick keys for Stella are: Y = UP, G = LEFT and J = RIGHT).
The Room # is now the first 4 positions of the score. The robot's X value is the last 2 positions of the score. In the topmost strip of the room I've turned on all 8 pixels for the sprites. These are positioned using the traditional position object routine so that the results of the Early HMOVE routines can be compared with the expected value.
