I loaded this .bin on a Supercharger plugged into a 7800, and noticed something unusual about the invader's movements. When they start on the far left, they all line up correctly. On the next movement, the second invader (from the left) stays in the same position, but one 'pixel' to the left of their correct fourth position. In the fourth position, the second and third invaders move into the desired position. On z26, the invaders do not display this pattern. On the Supercharger, it does. Is it a difference between the 2600 and 7800, or does it occur on the 2600 as well? Frame 1: XX XX XX XX Frame 2: XX XXXX XX Frame 3: XX XX XX XX Frame 4: XX XX XX XX I should make a more scientific investigation of the phenomena, but I want to be sure it's not something in the code first :) _________________________________________________________ Do You Yahoo!?
