Rockman 3: Stalker Attack is a ROM hack of Mega Man 3 that is itself a modification of the ROM hack Rockman 3: Burst Chaser. Like with that romhack, the main change is that Mega Man goes faster. Unlike with that romhack, the level and graphic design has been changed accordingly, with different boss mechanics and new enemies. The only things that have been retained from Burst Chaser is the changed music and the enemy and boss AI.

NemoRuby improves the previous TAS by 10.103 seconds, thanks to improved routing and better optimisation.

You can find a tracklist of the music used in this romhack here (Japanese only).
