Some users felt that the original NES Batman by SunSoft was too difficult to beat with just 3 lives. Some of the later battles were extremely hard and the game could get a bit repetitive while making your way back towards a failed boss encounter. This hack aims to make the game a bit easier and adds multiple paths to some levels. Give it a try and let us know what you think!
