Rockman 2: Basic Master is a ROM hack of Mega Man 2 that overhauls a good chunk of the game. Included are new levels, new music, new enemies, and different behaviors from existing Mega Man 2 bosses. There are also some neat shoutouts to other video game franchises to look out for.
CUI plays this game to completion as fast as possible by zipping through the majority of it, while also saving 4,127 frames over the previous publication.
WARNING: There are several instances of rapidly flashing lights during and after the Wily Stage boss fights, which may cause epileptic seizures for those affected.
