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.

No.22459 AJR Developer 3 days ago	Numerous VTech .dsk images available online appear to be bad, due to deletion of CR characters or insertion of LF characters.
No.22461 AJR Developer 3 days ago	Olivier Galibert's refactoring in 08f28cee11ce94e6656d4924c7a3c30614811783 broke this format rather badly... which is a bit surprising considering that he wrote the modern implementation in the first place.
No.22462 Robbbert Senior Tester 2 days ago	Thanks, works now. Took a while longer to find a floppy containing something that actually works though. Looks like most of what I have is junk.
