interesting, mine has the same soldered wires to the connector footprints, I assumed it was an operator hack job but maybe some of them shipped that way?

it looks like this might use the same pin configuration as Apoc's Irem M92 multi. So I'd suspect whatever solution Mitsu puts together for that will work on this as well.

I assumed as much for the electrical, I was more interested in how it mounts mechanically.

This is really cool. I'm curious how it's configured on the inside and what cabs it works with.

There's no standard, you need to figure out which chassis you have before I or anyone else can give you further guidance

First is to determine what monitor you actually have in there. A lot of Medium Res Montors are actually dual-res, and require either a switch or some connectors changed over to change between resolutions. As for other medium Res games A lot of other late 90s Midway/Atari Stuff supports Med res...

one of these days I'd like to 3D model a replacement panel bezel that fits a standard Sega style panel

As far as I know there isn't any drop in replacements. it's a 16Mbit SMD ROM which are difficult to find, and often don't have standard pin-outs so you may need to add some bodge wires. I think you can find them in 5V variants (though rare, they do exist).

For anyone who has one of my multis these are all ready to go. And if you want to build your own everything you need is on the github repo including gerbers BOM and placement files so you can order them fully assembled from the PCB fab shops. As for the M92 version. There's a small modification...

View: https://www.youtube.com/watch?v=9JOziw6_3E8 took me longer to make the game images than get the rest of it working ;)

very cool, I'll do some testing!

yup I can also confirm that speaker grills are a dark grey. also the area of the white plastic behind the grill (around the speaker) is blacked out with some mat paper so that you don't see the white plastic behind the grill. I replaced mine with some matte black vinyl wrap. I also covered the...

Do you have a reset point identified on the mobo? and can you share the pinout of the header near the rotary switch? if so I can start poking around at making it work.

80 gig file is original 30 gig file is the "bootleg" version. the 80gig file can be trimmed down to about 2.4GB without any data loss. Recommended trim size: 2436694016

Is sbx a hdd game? Did you rename the file to end in .hdd?

maybe try a faster speed on the .30 ROM?

no, just validate that the data is correct and that they're installed in the right slot

That to me looks like what you get when you're using the wrong data encryption for the security chip. the "security" is just encrypted graphics, so the game plays but you get garbage like this when it's wrong. that is to say, I'm sure your security chip is the right one, so I would focus on...

hmm all of my MS32 stuff is in storage but I don't think any of my boards are missing those chips. I distinctively remember comparing mobos side by side trying to work out what was different to make one work and the other not, and aside from a few small capacitors bridged across pins on a couple...
