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 4 where a charged shot of Super Armor hitting a certain wall will cause Mega Man Maker to crash. This level was deleted and reuploaded. This stage was 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.
