More specific to the CoCo / Dragon rather than a generic emulator.

Mess is all fine and good but I don't like the way the project has gone, 
I've updated the CoCo/Dragon emulation in there a few times but ended up 
having the changes undone seemingly at random by some other developer.

I could I suppose use an older version that still has the windows 
interface / menus, but I simply find the new interface to be frankly 
clumsy for mounting / un-mounting (for example)  images with the 
emulator running.

I'm trying to debug the DragonMMC interface software / firmware which is 
sometimes much easier to do in an emulator where you can suspend the 
emulation, single step etc.

Cheers.

Phill.
