This is a hack which replaces the main character Billy with his brother Jimmy in the main game and in versus mode. Jimmy must save his brother from the end boss rather than the usual Marian rescue. Jeff, the green palette swap of billy from the arcade game, is the end boss and also the opponent of Jimmy in versus mode.
This can be combined with the “Double Dragon NES - Arcade Mix” hack found on this site.
Created November 25,2007
This is a hack that changes Billy to Jimmy in the regular game mode. Marian was changed to Billy, so you must rescue Billy instead of her. The end boss was changed to Jeff, the green pallette swap of Billy found in arcades, cause fighting Jimmy would make no sense.
In the versus mode Billy was replaced with Jimmy, and the opponent was changed to Jeff.
It is strongly reccommended that this patch be patched on top of a game with the arcade mix patch found at Romhacking.net.
