With the current MESS, loading a disk ROM in a cart slot kills all floppy I/O. 
With RGBDOS in a cart slot, I get I/O for the hard drives (now two) but no 
floppy action.
This new MESS action prevents having a stock disk11.rom in a ROM directory with 
RGBDOS in a cart slot.

Having to type OK to get custom disk ROMs to work is a pain in the you know 
what. The only way around that now is to change the CRC value expected by MESS. 
That is not completely satisfactory if you don't want custom ROMs in both Coco2 
and Coco3 emulation.
