Megaman 2 Negative Daydream

A simple, unfinished experiment that was repurposed into a boss rush, with the main gimmick being that most of the colors are inverted. This hack includes:

• Boss-centered gameplay

• Higher difficulty

• Free E-Tanks from starting a new game or continuing from a game over

• Faster heads-up displays for both the Robot Masters and Mega Man

• New color palettes

• Modified Robot Master ASM

• Modified weapons

• Modified weaknesses

• A few sprite changes

Update (3/9/26): I have decided to abandon this hack after YouTuber NARFNra introduced me to a Japanese wiki that lists hacking notes for Rockman 2. Update (3/30/26): I'm currently working on a hack called Rockman 2 Maboroshi no Sho (The Phantom Chapter in Japanese).

• PineTools ~ helped me determine the hack's colors using the color inverter tool; I used this tool alongside an image of the NES' color palette: https://pinetools.com/invert-color Yum0987654321 ~ preservation of the hack's early versions; if I remember correctly, they also suggested the hack being a boss rush due to the strong focus on Robot Masters
