Game Boy Version Origins
When
Acclaim wanted a Game Boy version of
Double Dragon II,
Technos Japan simply took an already-made
Kunio-kun game,
Nekketsu Kouha Kunio-Kun: Bangai Rantouhen and changed the graphics, music and storyline to accommodate
Double Dragon's more realistic style.
DOS Version Source code
Disk 1 of the two disk 3.5" floppy DOS version without sound card support inadvertently includes a deleted file named
DRGNSRC.LZH. This is an archive containing multiple .ASM assembly language files that comprise the game's source code. The file can be recovered by using an undelete utility.
