Now i got an working Super Chase PCB (the last one refused to start). It's the Japan version so i guess i should dump it :-)
Did some pics and a video using my capturecard, check them out here: Super Chase pics and video The capture card did not sync properly thats why the top of the screen look a bit deformed.
The jamma adapter i soldered does not have all controls wired up... well.. it can't be played using jamma anyway, i need a potentiometer for steering. I could at least look at the attract mode and also start a game, i poked bit with a wire on the acceleration pin to make the car move a bit at the end of the video
