Title: Other Nintendo arcade machines not listed
Post by: SkylarTheNerd on 10 May 2018, 13:11

Mario Roulette - Slot minigame from Super Mario World
EVR Baseball - Like EVR Race, but with baseball
Test Driver - Also uses EVR

Not sure how these haven't been listed yet... I'll post more as I come by the info

The EVR games are likely to be electromechanical (no ROMs, no CPU(s), just mechanisms and motors and gears and relays and perhaps some logic gates). EVR player technology dates back to at least 1968 - see here for someone with a working player: https://www.youtube.com/watch?v=ywrbBJY5OUI (https://www.youtube.com/watch?v=ywrbBJY5OUI) . Anyhow, this means they're not a great target for MAME to emulate, as there's no microprocessors and barely even any semiconductors involved, really. This is the case with most other filmstrip-using games. For some others in the electromechanical category whose emulation capability is tenuous, see: https://mamedev.emulab.it/undumped/index.php?title=Category:Electromechanical (https://mamedev.emulab.it/undumped/index.php?title=Category:Electromechanical)

Still, MAME could - at best - possibly provide a simulation - or some future MAME spinoff project. Would need to see the circuitboards (if any) to know more.

Nevertheless, EVR Baseball is in the wiki already: https://mamedev.emulab.it/undumped/index.php?title=EVR_Baseball (https://mamedev.emulab.it/undumped/index.php?title=EVR_Baseball)
in the Nintendo list: https://mamedev.emulab.it/undumped/index.php?title=Undumped#Nintendo (https://mamedev.emulab.it/undumped/index.php?title=Undumped#Nintendo)

And yes, we should list Test Drive since we list EVR Baseball and EVR Race. We'll correct that.

Mario Roulette: https://mamedev.emulab.it/undumped/index.php?title=Mario_Roulette (https://mamedev.emulab.it/undumped/index.php?title=Mario_Roulette)
is in the Konami list: https://mamedev.emulab.it/undumped/index.php?title=Undumped#Konami (https://mamedev.emulab.it/undumped/index.php?title=Undumped#Konami)
(look at the flyer to see Konami's logo!)

I think Test Driver actually uses 16mm film, like Wild Gunman and the like.

Confirmed. This means (basically) that it's not really an Undumped wiki target as (generally speaking) there's no CPU, program code, or even complex transistor-transistor logic. Hence no entry for Test Driver. MAME currently has no framework to simulate a game that uses 16mm film and a high-level list of jump points provided by electromechanical schematics. Probably best targeted towards a spin-off project.

We'd need to see schematics/circuitboards that power these games to say for sure. With the exception of the Laser Clay Shooting System, which we're a little unsure about, we've been trying to keep electromechanical games out of the wiki. They may have films, but there's nothing MAME can emulate at a low-level. (Most of these tagged along via other information sources we imported: https://mamedev.emulab.it/undumped/index.php?title=Category:Electromechanical (https://mamedev.emulab.it/undumped/index.php?title=Category:Electromechanical) )

The EVR games are probably "on the bubble" so to speak, and we need to learn more about their hardware.
