Summary	08968: vz300 and clones: Floppy disks not working
Description	I have hundreds of the standard format of floppy disks that work with other emulators, and did work in the MESS days. They are 97KB and have the "dsk" extension, but are not the standard CPCemu dsk format. But now, although such a disk can be inserted into MAME, any DOS command will hang, making them all unusable.
Steps To Reproduce	Use this command as a template - substutite your own software and path. >mame vz300 -mem floppy -flop1 "E:\data\vtech\Laser200,210,VZ200\Disks\games.dsk" The machine will start up using DOS Basic. Enter: DIR It will freeze. You should get a listing of files. Or enter: STATUS You should get the amount of free space left on the disk. But, again, it will freeze.
