[Coco] MESS CoCo Emulation

[Pete Rittwage]

Is this broken for anyone else?

I used to be able to play old CoCo games under MESS with no problem.  Today,
I fired up Canyon Climber and the screen just goes crazy.  Many other
games crash before the title screen.

I'm not sure what the last version it worked was... I went from 0.148 back
down to 0.145 and all were broken.  There is nothing in the MameTesters
bug section, so I figured maybe I have some issue nobody else is having?

What is the last version to work, or is it just my setup?
