TeamEurope tackled 3 more Data East 8751 MCU's:
https://team-europe.blogspot.com/2019/08/more-mcus.html
We verified the current MCU dump of Bad Dudes as being correct.
Decapped and dumped the actual MCU from a Heavy Barrel (World) PCB.
Decapped and dumped the MCU from a Last Mission (US) PCB. For Last Mission there was no known dump for any region.
Dirk Best verified the Last Mission MCU dump as good and hooked it up for all of us!

There are lots more of these 8751 MCUs that need dumping... we could use some help. You can either donate a MCU chip for us to dump or donate a few bucks to Klaus for purchasing the needed PCBs. However, there are no guarantees that the MCU will produce a good dump or that the emulation will improve over the current simulation. But if things go well, these MCUs will be properly emulated.

Outstanding work as usual. Data East games fans should be happy with these specific fixes.
As for mcus being worked on, a Taito Cycle Shooting fan is going to be unhappy when he finds out his Taito game uses a different mcu and not the ones that have been done recently. I am certain the individual will have a "PacDude"-like temper tantrum moment once he knows this.

The hardware is an almost exact copy of the original Taito hardware,
minus the 68705 Microcontroller
dacholer.cpp: Dumped color PROM for Dacholer. [caius, The Dumping Union]

Thanks with update to comment to what is now shown below.

TODO:
- is the background color pen correct for both games?
