No square wave generators or hardware timers. And unlike other machines that used dedicated sound-generating chips like the AY-3-8910, the Williams sound board was just a 6800 CPU hooked up to an 8-bit DAC. Williams used the same sound hardware (and many of the same sound effects as well) on all their arcade and pinball games from the late 1970s through the mid 1980s. Instantly memorable, quintessential sounds of the arcade era.

Defender's sound effects kicked ass and were a big part of what made the game experience so intense.

There is a basic visceral appeal to it.Ī bit disappointed to see this repo doesn't contain the source code for the sound effects. It's like Yngwie Malmsteen's demo tape before his first album. It's like those characters from the older version of the Matrix: Difficult to kill. Stargate is a fun game, and these days I play more casually, not really trying to perfect my skill.Īs someone else in the comments noted: Defender is more raw.

I remember Eugene Jarvis and Sam Dicker talking about the Defender->Stargate upgrade process at the California Extreme arcade convention in 2014. I think this was because the Stargate chip was an upgrade-the faster CPU wouldn't steal time slices from me at odd moments, so the game was more predictable. What I noticed about Stargate back then, coming from Defender, was that it was easier to shoot things. For me, back in the day, I went from Stargate to Defender because the 7/11 got rid of their Defender and the Safeway on the next block got a Stargate :-) In fact these days it's the game I'm playing.

This is maximum difficulty on the first-run ROM chips, the infamous Green ROMs:Īnd if you're interested in an instructional video of how to play:ĭefender was a big game back in the day, grossing about a billion dollars worldwide. Here's a player, mikeville66, whose video inspired me to get better.

The above is running on JROK - custom silicon to emulate the original chip (much better than MAME), it's contained in an original cabinet, with an original monitor, and a custom built control panel, designed to be as authentic to the original as possible, and hand-built by Jim Bowley. For a brief moment, about four years back, I was the top player on the Williams Defender Players Unite facebook group at hard difficulty settings:Īnd, for the hackers, here's a version of the Defender ROM, modified by a programmer named Jim Bowley, to render an impossibly difficult version of the game:
