I meaned about bonus game on M72 like R-Type II (World version, converted from M84), Lightning Swords (known in Japan as Kengo, converted from encrypted V35 M84) or Pound For Pound. Any chances for in same card R-type trilogy (1,2 and Leo)?

Hmmm, any idea what games other than the soccer have that mobo? I can dig them all out if we need too.

M92 games that might use the M92-B-G PCB:
Dream Soccer '94,
Gunforce 2 / Geostorm
Ninja Baseball Batman
Superior Soldiers / Perfect Soldiers

Irem used other model B boards for these games too, so you have to check and specifically see if yours is labeled M92-B-G.

I have some genuine M92-B-G rom boards.

In Korea, some NBBB pcbs were distributed with M92-B-G rom board.

Maybe M92-B-G rom board is made for GeoStorm(Gunforce II).

1990s, NBBB was very popular in Korea. but GeoStorm was not popular.

So many NBBB pcbs were distributed with M92-B-G rom boards.

Anyway, I can send it to him too.

Great, the only one of those I have is NBBM, which I posted! I'll look at my other 2 NBBM boards when I can find them.
 
Second NBBM no luck, once I find the third one, I'll post. Meanwhile, enjoy my most corroded M92 PCB, Hook! I don't often see good pictures of this one and mine has a nice label (much different than other M92 games), so enjoy the pics and oh, Get those fucking caps re-done people!

Awesome to see progress on this. I need to pull all my M92 boards out and check on them. Is the M92-B-G board still needed?

Hello everyone. There has been a lot of renewed interest in an M92 multi lately and since we've been told we aren't stepping on any toes we are announcing two designs for an M92 multi that we have previously developed but not finished because others were working on it. Since they have said it's ok, we are going to finish our designs.

The current part situation means we will be releasing one multi sooner than the other. Below are the descriptions. Choose the one that's right for you!

Option 1: This option uses a full new romboard including the repro of the 0BJ8 custom chip and it is compatible with ALL donor pcbs since only the motherboard is needed. This option is mostly complete and we already have a proof-of-concept.

Option 2: We are now working on a "simpler" design which is midway between a full new romboard and modules plugging into the OG romboard. This version will also be compatible will ALL donor pcbs. This option will also be the cheaper option.

More info and pictures coming very soon!!
