That's right: - Create virtual formatted blank disk on Rainbow 100. - Load that blank disk on PC AT environment using the DOS driver I linked above.* - Copy the files to the blank disk.**
Make sure to config and use properly the disk drive you need. MAME can't tell the difference between double density and high density drives/floppies. Mixing them makes the disks unreadable (i.e. a 5 1/4 DD drive can't read a 5 1/4 HD floppy).
*Given the context you already know DOS, I don't need you to explain how a "DEVICE=RX50DRVR.SYS" works on config.sys. **You need to copy them beforehand with any of the methods I described before.
