I made a new audio ROM tonight with the overused "SHOOT THE PYRAMID!" callout removed. I just found it a bit annoying that it yells that repeatedly, even at times when that is not necessarily the right thing to do. There are still occasional callouts like "in the pyramid, in the pyramid", "get in the pyramid", and "up the middle", so it's not like you're going to forget to shoot for the pyramid.
I played several games with the new ROM, and I do feel it is a definite improvement.
I've got one tube of 4Mbit EPROMs on hand, so if anyone wants a burned ROM just let me know and I can send you one at minimal cost.

I shared my modified audio ROM (with "SHOOT THE PYRAMID!" removed, see this post: https://pinside.com/pinball/forum/topic/stargate-owners-club-shoot-the-pyramid/page/9#post-2256297 ) with a couple people here. How are you liking it? I don't miss that callout at all.... I'm actually thinking I might want to remove "in the pyramid, in the pyramid" too (or maybe replace it with something new). That would still leave the occasional "get in the pyramid" and "up the middle".

I have the v5 CPU image somewhere. I also created the audio ROM with the "Shoot the Pyramid!" call removed. Send me a PM and I'll hook you up.

If anyone needs a burned audio ROM, I can send you one for $15 shipped. Add $10 each if you need the CPU or display ROM.

Sure. It’s a simple change to the audio ROM. The audio sample for “shoot the pyramid!”, which gets called far too often and tends to grate on peoples’ nerves, has been muted. I left the other miscellaneous pyramid callouts, since they are used far less.
You just replace the AROM1 EPROM on the audio board (upper left board in the backbox) with this modified chip and life is just a little bit better.

Just to clarify, that post is just saying to not bother changing anything in the reset circuit UNTIL you move up to the v5 code ROM first (as it may address your startup issues). Changing resistors/caps is not a prerequisite for running Stargate v5 (on any board).
