[Coco] MAME problems .186

I've not kept up with MAME/MESS for some time so don't know when this started. I just obtained the 
current version which is .186. I'm using the stock windows 32-bit precompiled version.

By default, all Coco versions seem to be limited to non-disk operation and when you get disk access 
operable, it is limited to two disk. I've found how to force four disk access but this must be done 
each time you start emulation.

Here is what I've been forced to do.
Each .ini file for coco2, coco2b, coco3, coco3h, and coco3dw1 must have the following added:
#
# SLOT DEVICES
#
ext                       fdcv11

The default for the above which won't be in the .ini seems to be     pak        . If you have fdc 
instead of fdcv11, you won't be able to have real time clock access.

To force four floppies after having set EXT to fdcv11, it was necessary to (Windows software) get 
into the menu with Scroll-Lock then Tab. With the menu open, go to Slot Devices and for flop2 and 
flop3 set them to QD.

Has anyone else observed the above?

Also a major problem with coco3, coco3h, and coco3dw1 emulation is that they are set to autostart a 
cart. The effect of that is to prevent the coco3 Super Extended ROM from starting correctly. It is 
necessary to use Configuration and turn OFF cart auto start.
Unfortunately, the menu selection is not always present.
