Laser Ghost, with distinct 'set 1' and 'set 2' releases and US/World versions, hints at a game with multiple regional versions and possibly differing game content or difficulty levels. The decrypted nature of the ROMs suggests that these releases are for emulation and preservation purposes and further information would need to be sought on the original developer.
