Hi Phill,
I have been lucky enought to find them fast than expected
That game was complicated to convert due to its length.
I attach in the zip two folders, one for the 6809 version and another for the 6309 version of the game
Each folder has four files:
A binary for graphic mode artifacted PM4 and a convoluted basic loader/modifier
A binary for PM3 mode and its basic loader
Both basics use an old version of ML code that does a PCLEAR0, then it modifies the code at three points
where the game reads the joysticks so that they create NO noise on the Dragon. CoCo ROM is clever for that!
Finally it adds a small routine to silence output before reading joysticks at $01E0
and finally it execs the game from $f9a
So, I am sure you could use the binaries as they are to test MMC, because the changes the Basic does
are not modifying severely the game behaviour ...
Any question that could arise, just let me know and will try to be of help
cheers!

Ps I have included a disassembled listing of the full game, you will see commented the points
where the CoCo calls the joystick and that 'new' code added to the end of the file ...
