I have 720kB [.DSK] files. How can I make a multi disk image of it (to use with fMSX-DOS or with FDD emulator)?
This is quite clearly explained in the manual of fMSX. But to make this FAQ more complete, I’ll repeat the explanation here. Multi disk images are supported from fMSX-DOS version 1.6b1. To create one, simply copy several disks to 1 image like this: COPY /B DISK1.DSK+DISK2.DSK MULTI.DSK, start the emulator with the resulting disk image as disk A, and press RIGHT CTRL+1..0 when the game asks you to insert a new diskette. Please note that this only works for double sided disk images (720kB ones). An alternative: [multidsk.c]: C source of a program that can add and extract [.DSK] disk images to/from multiple [.DSK] files. Compile it yourself on your favourite platform. Written by Sean Young. For Win32 users there is a binary available. If you like to do this job on MSX (on a harddisk), tye the following in MSX-DOS 2: concat /b disk1.dsk+disk2.dsk multi.dsk. This is useful if you want to run a multiple disk game with a so-called floppy disk emulator on MSX, which enables you to play floppy
