BLOCKBUSTER is a disk sector editor program, ala "Disk Doctor". In addition to reading and writing standard sectors directly to the disk, BLOCKBUSTER is able to read information 'hidden' beneath most errors, and can read tracks 36-40. BLOCKBUSTER also also has a number of other useful features. BLOCKBUSTER is intended for use with an unmodified 1541 drive. It is presently incompatible with the 'FLASH' 1541 ROMs, but IS compatible with the FastLoad cartridge by EPYX.
