EMUTIL is a disk image archiver for the Commodore 64 and 16K+ CBM/PET computers. It supports all known Commodore disk drives, of all capacities. It also supports all CMD HD and RL Native partitions. EMUTIL creates and dissolves single and multiple archive images. The images may be RLE compressed or uncompressed. A single uncompressed archive image of a 1541 disk is equivalent to a .D64 file, so it will handle those just fine, though it is intended to cover disk drives unsupported by other programs, such as the CBM 8050/8250 and CMD Native drives. The program is a collaborative effort by Bo Zimmerman and Andre Fachat.
