dumping ROM banks?
 

it is possible to dump the RAM banks, but I didn't find the function to dump the ROM banks. I'd like to dump them in order to have a backup copy. Or ist it impossible to overwrite the ROM banks?

ah, I'm happy, you can't store to ROM banks ;-)

If you have to.

Copy a midi bank using your computer, ie copy paste. Name it RomA_backup.mid. Load Virus Control, in the browser show RomA on the top half and RomA_backup on the bottom half. Select all the top half and drag to the bottom bank. Done.
