Wiring is hooked up to reduce the video singal when a button is pressed. This is frame-by-frame (field by field, actually) of the resulting images. In this case, I've also wired down and roundhouse together so there's an obvious transition. Test performed using an SE stick in practice mode at turbo 3 and recorded with a Canopus AVDC.
(Note: Numbering has been changed to make it consistent with other images on this site.)
| -1 | | |
| 0 | | Down and a button are pressed near the top of the frame where the image goes dark. |
| 1 | | No change on the next frame |
| 2 | | or the second frame after |
| 3 | | or the third frame after.. |
| 4 | | This is the first frame that shows Ken in motion. The combination of button and direction input forces an instant crouch which is easy to recognize. |
