OK, I've tested with MESS .143 .

With MESS, if you don't want Extended Basic present, you should use coco 
emulation not cocoe, coco2, coco2b or anything else. I've tried coco2 emulation 
and while you can remove the disk11.rom you can't get rid of the extbas11.rom 
and get emulation to start.

This version still supports messui.exe and with my Windows system, I find it 
easier to set parameters using messui.exe than mess.exe. Even with coco2, I can 
set and get PCLREAR1 PRINTMEM 13095.

Now, I find MESS .143 slightly buggy. That's because setting parameters for 
specific emulations does not always take. It helps when using messui.exe to set 
the paramters for say coco and then kill messui.exe. The next time it starts the 
parameters usually take.
MESS uses the sub-directories cfg and ini to store parameters. If you set 
parameters or even used coco emulation, you should find a coco.ini file. Right 
clicking on an emulation in messui.exe permits selection of properties and there 
is a configuration panel for selecting memory size.
ROMs are stored in the sub-directory roms which either holds zip files or more 
sub-directories for each emulation with .rom files.

When coco is set for 16K and started, you should see

I think that further discussion would be better off this list by direct e-mail.
