When the game was ported to the PC-8801 computer by Enix, the game featured an introduction to the game and a whole new ending featuring cinema screens showing a battle-torn Clovis and a teary-eyed Celia. A harder sequel called Dragon Buster 100 was created for a Japanese TV Plug-in-play game along the original. It had horizontal levels with four enemies and a dragon (the last one) on each one. Once all 100 enemies are beaten, the game repeats back to level one.
Dragon Buster was also included as a hidden minigame in Tales of the Abyss.
