haha, man I wish I could... Probably be another couple hours before I can get to it again, but I do have a question - should I want until the garbage starts to show up before pressing on the decoders, before, or both?@Fynflood I need you to move 2 times faster! LOL
Ok, with the cabinet pulled out and the door wide open, I was able to play for about 20min with no glitch. Ended up surrendering my last life, and when I saved my modest score of 46k I saw the first hint of glitch on the highscore screen.@Fynflood I need you to move 2 times faster! LOL

That's true. I've yet to use this feature! Feels like a solid use case for it lol.Not much to add to the technical discussion... but if you look above the monitor, I believe there should be an angled mirror-like piece of metal. If you take the bolts out of the monitor tray and slide it back to the next set of bolt holes, you can see the monitor's reflection in that mirror from the back of the cabinet.
I'm going completely by memory from how my Joust is, but I'm almost certain that was a factory feature on all Joust cabs.

gamefixer and I extracted them from games to just use as mirrors. it's only good if you're standing at monitor level, as it was intended to adjust the monitor from behind.Not much to add to the technical discussion... but if you look above the monitor, I believe there should be an angled mirror-like piece of metal.

Yeah those temps are well withing spec range and don't bother me alone. Add this weird problem and I start getting ideas lolgamefixer and I extracted them from games to just use as mirrors. it's only good if you're standing at monitor level, as it was intended to adjust the monitor from behind.
also I can assure you heat has no effect unless you have failing parts. the 4000 scores on high score table may be indicative of something else being wrong. are you using a switching power supply? does it routinely give you the factory settings restored message when you turn it on?

it isn't. that means the 5514 CMOS is failing. this can show as 3-3-3 errors on the rom board error display on boot or you can get a CMOS FAILURE message on the 3rd screen in test mode.Yeah those temps are well withing spec range and don't bother me alone.

I do have a switcher installed. It's got the arcadeshop adaptor on it, was installed when I got it (I've asked @braedel if he has any of his left). It was giving me the factory settings restored message until I fixed the battery holder. It's pretty clean, but the middle battery contact was destroyed. Fresh batteries in, and it's not complaining any longer. As noted, scores are not saving, but the settings are. Might also be worth noting that the highscores seem totally random and different each time I turn it on. Not sure if that's normal or not.

Arcadeshop adapter it's entirely normal for it to eat away at scores, but you presently have numbers for initials and that's probably not good. I wanted to engineer a CMOS article for my site a couple weeks ago, just didn't do it.
apparently Jameco doesn't sell them anymore. https://www.digikey.com/en/products/detail/rochester-electronics-llc/HM1-6514S-9/12095588
ditch the AA battery holder and go lithium
video nowI've got a CR2032 holder, a full set of 74166's and a handful of 5514s on order.
I turned it on today and played a bit. Thought I'd leave it on for a while, so gave it a couple of hours. Screen had eventually glitched and froze. Now on a reboot I get All Systems Go (0 on the ROM board) and then it shows the Factory reset screen. I cannot get past it - it resets before the game loads![]()

So in theory the 5514 will get me back into business? I just noticed that 1C on the board is a HM4334P-3, but in the schematics it's a 6514 - I assume 5114/6514/4096 would all work, yeah? Or maybe I go with an NVRAM adapter?your CMOS is toast, sir. it's crash/resetting on the high score table because it's THAT corrupt. I've seen this happen mostly on Sinistar, never on Joust.
