You can create a bootable CD image from
ISO header file and Menuet floppy image.

1) Download and unzip isohdr.zip and Menuet image

2) Combine the header with Menuet image

   Dos:  copy /b isohdr + M64-xxx.img m64boot.iso
   Unix: cat isohdr M64-xxx.img > m64boot.iso

3) Burn m64boot.iso to CD and boot

Note that the CD image is for booting only
and does not include a iso9660 filesystem.
