This is the video that I get when I power up Ataxx on my JAMMA supergun. I believe it to be some sort of sync issue, but efforts to fix it by fiddling with the game's JAMMA adaptor have failed. The garbage is representative of what would actually be displayed onscreen; for example, that rather large streak of static at the bottom of the screen is, in fact, the INSERT COIN graphic, and it flashes on and off just like in the normal game.

This is another example of representative garbage. This is the initial input screen; the three lines on the bottom left (not the 3 sets of 2 lines) are the initial placeholders in the normal game. Additionally, the slanted garbage that wraps to the opposite side of the screen is the large grid of letters. Moving the joystick causes a stretched-out garbage cursor to move onscreen.

The game's sound is perfectly fine and, beside the video issues, the game is working great. However, things get worse. When run on my arcade cabinet, things are VERY different. I get absolutely no video, as well as no sound except for a buzzing noise! This is very different from what I get on my supergun, and the lack of any sound aside from constant buzzing especially bothers and baffles me. Any ideas?
