[Coco] Help with MacMAME (Tony Schountz)

[Barry Nelson]

Typically, you would NOT unzip the ROMs before placing them in the ROMs 
folder for MAME. MAME scans zip files in the ROMs folder. The zip files 
should be named "name_of_system.zip", for example coco3.zip. If you DO 
unzip them, you must create a sub folder under ROMs named with the name 
of the system and place the individual files for that system in that 
folder. The names of those files are determined by the system.

Just getting to this after quite a long time (Mac mini M4, Apple 
Silicon).
I downloaded the coco3h.zip file from the CoCo archive and placed it
(coco3.rom and disk11.rom) into the "rom" folder in my (Mac) home folder
(~/roms). MAME sees the ROM file, "Color Computer 3 (NTSC)". However, 
when
I select it I get an error message:

"Required ROM/disk images for the selected system are missing or 
incorrect.
Please select the correct image or select a different system." I have 
also
tried all of the other coco3 roms on the archive with the same problem:

coco3.zip
coco3dw1.zip
coco3h.zipcoco3p.zip
coco3_hdb1.zip

Of course, they are all unzipped before putting them in the roms folder.
Any suggestions for how to get MAME running a CoCo3 emulator?

Thanks,

Tony
