Contra: Gender Swap
魂斗羅
tavuntu's graphics hack that turns Contra's two commandos into women, built on the English translation of the Japanese Famicom version.
What it changes
The hack redraws the two heroes so Bill Rizer and Lance Bean become Bella Rizer and Lana Bean, with the names changed to match. Everything else about the game stays as Konami made it.
It is built on top of Ferraro's English translation of the Japanese Famicom release, so it keeps that version's extras, such as the story scenes between stages and the stage map, with the text in English.
Playing it
The patch is applied to your own copy of the Japanese cartridge, following the instructions that come with it.
