[Coco] Help with MacMAME

Barry, thank you for this information; that probably explains why I 
couldn't get rid of the floppy controller rom without Mame throwing an 
error. At least that part of my question is answered from my post...I think.

Regarding the rgbdos rom image, as I mentioned I was able to put it 
inside a "coco3.zip" file (I couldn't get anything else recognized; 
ideally, I'd like to create a "coco3rgb.zip" file with the CoCo 3 rom 
image and the rgbdos rom image in it)...

When I started it, it complained about the image not being right, but it 
did load up rgbdos (then failed to find a hard drive attached); I don't 
know if just adding a hard drive image to Mame will work or not. I may 
not even ultimately need it; I only want it because that's what I have 
set up currently on my VCC/OVCC configuration (because I have this 
long-dormant project to take and re-arrange my old floppy images into 
something more coherent than what I had as a kid - because I did crazy 
stuff with my floppies, because they were so expensive, and my parents 
could only get me a few at a time - so I have floppies with like, both 
music and images on them, and now I'm creating a bunch of floppies in 
"groups" - one group for images, one for games, one for utilities, one 
for music, one for etc...)

Though maybe since I haven't touched it in forever, there might be a 
better way, but I'm not sure; all of these old images of mine are 
formatted/work under Super DECB...the majority of the images use that, 
and are not formatted/configured, with only a scant few, for OS-9 (and 
most of those are actually the kind of OS-9 floppies you start using the 
"DOS" command).

Unless HDB-DOS might be a better way? In short, I'm kinda using 
individual floppies as "sub-directories" (each floppy image is named 
with an 8.3 name, with the 3 character being "the number" in the series, 
and the 8 alphanumerics characters as a name of sorts (ie, 
"GAMEHOFK.001" meaning "Game, Hall of the King, disk 1" - something like 
that); based on what I've tested (or at least, if I remember what I was 
doing before correctly), these floppy images will then be able to be 
loaded on an SD card for the SDC (and they could probably also work with 
a gotec and/or drivewire).

So I would have 255 floppies, with the zero-th floppy being the 
"autostart" boot floppy for the SDC (which loads the RGB-DOS part - I 
think that's how I was doing things - it's been a while)...
