The DDR4 problem can be worked around with if you do something like this in the driver machine_reset:
m_maincpu->space(AS_PROGRAM).write_byte(0x05, 0xff);
I've now made the usual changes for these 6301 devices and with the above line the Yeno 301 XL is at least starting, but apart from the buttons (producing beeps) nothing else works: no leds and also the sensor board is 'dead'.

And the illegal opcode fixes, the ones I linked should be easy to copy over to an older MAME.
Well, I've looked at these files, but there are hundreds of changes, and the current m6800 files are so different to the version I'm using in 0.220 (although already updated some time ago), that I won't even know where to start with any "copy over".
So this Yeno 301 XL will definitely not make it into CB-Emu.
