Are you using the correct ROM images? The JVC emulator does not use the same ROM 
images used by MESS and VCC.

Your ROMs must have a two byte header (Intel order) indicating the memory 
location of the ROM.
coco3.rom header = $0080
disk11.rom = $00C0

You may also want the zero byte file 2MEGS present in the emulator directory to 
get more than 512K of RAM.
