This is a miniature Megaman game, 'Megaman Legacy' which contains 6 Robot Masters from 6 different Megaman games, and 4 Wily stages, including Boss rematches in normal flat boss rooms. To be played all at once, hard reset will lose all progress, there are quit stage rooms before the boss room in every Robot Master stage, and you can return to stages to acquire any missed E tanks after obtaining the necessary powerups.

There was a bug in Mr. X stage 2, where weapon blocks would incorrectly remain in place after being destroyed if you reached the stage without dying, making a 0 death run impossible. This stage has been modified beyond the bugfix since the original (Deleted) version at: 525575

Speed runs are not comparable between the 2 versions due to the addition of more screens, enemies, and platforms in some key areas. As well as a few minor changes in a few stages.
