Chaos Strikes Back for X68000 3.1 (Japanese) Cracked.hdm
This version is cracked. Original files have not been modified. A crack program CK.R was added into the disk image, and AUTOEXEC.BAT was modified to run CK.R before running the game. The CK.R crack works by intercepting read attempts of the copy protection sector on the floppy disk and returning the expected data to the game.
