MSX disc creation

[dom]

I've just merged support to create MSXDOS format discs (720k DSDD discs)

This can be used from two different ports:

zcc +cpm -subtype=msx -create-app

Will create a CP/M program that thanks to the ABI compatibility will work in MSX-DOS

zcc +msx -subtype=disk -create-app

The disk subtype has been extended to additionally create a 720k DSDD disc image.

I'm resurrecting this old post to drop an idea for the future, I discovered that Multiplan on the MZ-2500 had its own 720K floppy disk format and booted a custom version of MSXDOS.
Z88dk is already able to create native boot disks or CP/M compatible images for the Sharp MZ-2500, but a FAT based package is in theory possible.
Also, seeing AUTOEXEC.BAT and COMMAND.COM on a Z80 computer surprised me, I could even create a file with COPY CON..
