Exidy's President Pete Kaufman was unusually forward things before he passed. He basically gave all of Exidy's old ROMs to MAME himself. How wild is that? But most of Exidy's '70s output wasn't ROM-based. So they're just not there.https://www.gamasutra.com/view/news/247873/Obituary_Exidy_founder_Pete_Kauffman.php …

This includes Death Race, which is not just the most important game in Exidy's catalog, but one of the most important games of the '70s. Every day that I think about how we're missing games like Death Race, I get upset.https://www.youtube.com/watch?v=ZY9hQQkV1zs …

So you're next question is inevitably: how the hell did *I* get all that footage? I swear, I've been waiting for someone to accuse me of hoarding undumped ROMs, lol. But I guess no one really noticed? Which is why its so important to raise awareness. Anyways, I'll fill you in.pic.twitter.com/UBbEM5sQIJ

Let's start with Death Race and work backwards. Although it doesn't exist on MAME, you can play a reasonable simulation of it at the link below. I don't think it's 100% accurate, but it looks close.https://fabslab.itch.io/death-race

Death Race was a sprite swap of Destruction Derby (aka Demolition Derby), so for the magical transition between them I just manually recreated the computer-car sprites from existing screenshots and then manually animated them in After Effects.https://www.youtube.com/watch?v=5kRQ2OEJkNY&t=75s …

Atari's Shark JAWS is emulated on DICE, an old integrated-circuit version of MAME that is no longer supported. EXCEPT it doesn't include the graphics ROMs, so you end up with nonsense unless you can find those. Thankfully, a friend sent me them. https://emulation.gametechwiki.com/index.php/DICE

Just to clarify (I'll be doing a bit of that in this thread, apologies in advance), DICE was never a version of MAME. It was its own separate project that tackled the issue with combined analog/digital netlist simulation prior to MAME doing so in recent years.

Yeah, I could've worded that better...I'd meant it as "similar to MAME" not associated with MAME.

No worries, just a minor point! About the only other clarification is that other than a small handful of Pong-like derivatives, most CPU-less games in the 70's *did* have ROMs, just not as we think of them today. You did allude to this later, though. :-)

At this point, MAME's netlist simulation tech is pretty bulletproof when dealing with circuits that are primarily digital logic, so theoretically, it would be trivial (but grind-y) to bring up any of these discrete games for which ROMs are dumped, given schematics. BUT -

- the main issue I found when going ham on some audio netlists, as well as Atari's "Tank", during my month-long summer vacation last year, is that the quality of most schematics in circulation tends toward the unreadable end of things.

Most of the scans that exist date back to the mid to late 90's, when disk space (and bandwidth) was at a premium, so they tend to be PDF'd versions of 1-bit scans, and they tended to be scanned with little (if any) quality control on the schematics themselves.

While things like the BOM (for manuals that included one), and the service-related text tends to come through just fine, schematics suffer from everything from "lost" traces, to unreadable part values, even to unreadable part types.
