Richard,

The JVC emulators will not work with some modern OS and disk formats. For 
example, with Windows and WIN98SE or earlier you are fine. With WinXP, you will 
need a FAT32 format drive and appropriate config.nt and autoexec.nt files.

The JVC coco3 package should have contained the roms coco3.rom, and disk.rom. 
These roms are not the same as the ones used for MESS and VCC. The coco3 JVC 
emulator can use RGBDOS if you want it.
To be sure that you are using the right roms, delete DRIVES.CC3 and GENERAL.CC3 
after changing any rom names.

For maximum memory with Disk Basic and OS-9, you need the zero byte file 2MEGS 
in the emulator directory.

The disk images used with the JVC emulators must be exactly the correct number 
of bytes or have a header indicating the size and number of side. That can cause 
problems with NitrOS-9 disks.

======
Where did you get the emulator and rom packages?
