Lol for $15k maybe @Apocalypse would wanna make his own repro

For the very good price of only $1500!
I'm down for buying a board if someone make a repo of the original. I love weird stuff like this.
I just now noticed that the original board has unpopulated controller ports on the bottom. That's a neat feature.
As for 4-player support in Neo Bomberman, there's no such thing unfortunately:

I translated the schematic into KiCad, but as my MVS has no output port to multiplex the controllers I didn't go further.

(I only looked at the controller stuff, not the video amplifier.)
Edit: MVS-Scans has some good pictures:

I would probably try to integrate it with a supergun - but as only one game uses it I don't know how much demand there is...
@totologic does neotris work with this?
Edit: Thoughts for supporting this on MVS that don't have the output port:
- directly solder to the NEO-D0 on the motherboard
- mod board that snaps onto the CPU, similar to https://www.neogeofanclub.com/projects/neobiosmasta-vmc
- mod board that solders to the back of the prog connector
- add the connector to the prog board of a game that supports 4 player

Bomberman could be a fun homebrew project for someone... there are already a bunch that you could rip off some of the code and graphics, though it shouldn't be too hard from scratch even for a beginner...

I'll send you a 1B if you're interested in working on a repro board?
If I really wanted to I could just buy a 1B board ...
There is not much to it, you can translate Furrtek's schematic into KiCad, and then layout it. Let me have a look tonight if I can find the stuff I have so far.

Of course. I just have extras I have no use for!
EDIT:
Personally, I would like to see a board that handles the 3P and 4P controls, passthrough for everything else. I have enough gear to split video and audio already. My 2p.

Let's see if we can do a trade.
This is what I came up with. Pass-through for Jamma, P3 and P4 on DB15. Some extra headers to allow some extra wiring options. I probably missed a few things, as I had to move things around from the old project... (EDIT: Yes, I have quite a few fixes already. Sigh. Always immediately after posting something,)
And can someone confirm what is going on in the circled areas?
Edit: Updated schematic with CRE401 replacement. Can someone confirm the capacitor value? I get ~35pF
Edit: Sigh, I noticed the inputs are out of order. I'll fix it tomorrow.

Quick layout over lunch:
I'll still have to move things a bit to have more space for routing. The pin header on the right is IGS PGM compatible, so you can use https://www.arcade-projects.com/threads/4-player-igs-pgm-adapter-cable-replacement.10274/post-259342 to relocate the connectors.

Complete layout (for now):
It is quite likely that I've forgotten something. I'll stare at it for a few days before I order it, and I'll try to get a few measurements of the JAMMA edge as well.
All signals except for the controller get passed through to the bottom edge. Player 3/4 go to the IDC connector and the DB15 connector, Player 1/2 go to the bottom edge.
