Mega Man 6 is a platforming game for the Nintendo Entertainment System.

A robot battle tournament was held by the mysterious billionaire Mr. X. Eight Robot Masters from around the globe was invited to participate. But during the event, they went berserk and commandeered by Mr. X declaring his intent to rule over the world. With plot seems familiar, Mega Man decided to stop Mr. X like what he did with Dr. Wily, who mysteriously went missing.

A new support feature for Mega Man is added, namely Rush the robo dog fuses with Mega Man to form Power Mega Man, a wall-busting armor, and Jet Mega Man, a short flight ability armor.

This hack makes the player start the game with both the Jet and Power Adaptors in his inventory, something that can not be done with passwords or cheats.
It also makes sure that the player has both armors no matter which password he enters.

As a consequence, on the "Weapon Get" screens at the end of Plant Man and Flame Man stage, the messages related to acquiring the Adaptors are gone.
