Not all of the MCUs for the M72 hardware have been dumped. This was mentioned a while back by @rtw but has since been burried in the M72 thread:

Missing MCU dumps (M72)

Air Duel (World) - MCU labeled AD C-PR-C
Battle Chopper (World) - MCU labeled MH C-PR-B
Daiku no Gensan (Japan)
Dragon Breed (World) - MCU labeled DB C-PR-B??
Gallop (Japan) -
Ninja Spirit (World) - MCU labeled NIN C-PR-B

NOTE:
After the MCU is dumped it can easily be written back to an 8051!

Do you own a M72 Multi? was it originally one of the games listed above? Do you want to help preserve this hardware?

If you answered yes to those questions then please post up below with which game you have and where you're located so we can work out how to get your MCU Preserved!

Thank you.

A Gallop - Japan version is on sale (ive seen it) and can be dumped if the next owner will wants to help
 
I checked what MAME currently lists as missing:

Air Duel (World) - MCU labeled AD C-PR-C
Gallop (Japan) -
Battle Chopper (World) - MCU labeled MH C-PR-B
Ninja Spirit (World) - MCU labeled NIN C-PR-B
Dragon Breed (World) - MCU labeled DB C-PR-B??
Daiku no Gensan (Japan)

All these are the M72 versions.
 
There's also an undumped USA romset ( not MCU ) version of hammerin' harry on the M82 if anyone has that to dump.
It's a confusing PCB as the chips may have M84 on the labels but the board will be a full size M82.

Also there's a undumped world version of hammerin' harry on the standard M84, we only have a dump of the bootleg.
 
Last year I seen the m72 world version of air duel sold on eBay for $999 and the board had a sticker with the phone number for the American branch of irem. Air duel was never officially localized in the west and that version of air duel turned up in a Denver arcade; also, the version of air duel I own was location tested in a Seattle arcade. The person who dumped the board was Jon exidy and I think he still has the pcb. I was going to buy that pcb but the price was alot of money and I had already own the m82 version.

I remembered to check my Air Duel, and it's just labelled AD C-PR- so I'm guessing this is not the MCU you are looking for?

Yes yours is the JAP version, already done.

Thanks for checking it out though!
 
That one seems to be dumped, but thanks for letting me know.

Checking back on this, Air Duel was done according to m72.cpp in MAME so just the following remain:

Battle Chopper (World) - MCU labeled MH C-PR-B
Daiku no Gensan (Japan)
Dragon Breed (World) - MCU labeled DB C-PR-B??
Gallop (Japan) -
Ninja Spirit (World) - MCU labeled NIN C-PR-B

Bump!
