1.6.1 is a minor update to Mega Man Maker that was focused on fixing glitches and added two missing aesthetic assets. It was released by Luigi on February 26, 2020.
- MM3 Wily BG 2 is now visible in the BG editor UI.
- MM10 Endless 30 tiles are added.
- The disclaimer lists 2019 as Capcom's copyright year rather than 2020.
- You cannot join a locked multi-editing room by entering the ID.
- In multi-editing rooms with editing disabled, you can open the weapons and music menus using the keyboard shortcuts.
- In multi-editing rooms with editing disabled, you can toggle a section connection.
- Pile Driver can clip you through walls if you hit something close to a ceiling.
- Jewel Satellite deflects off various objects, such as Force Beams, Rotating Platforms, Sheep Blocks and various other gimmicks.
- Wheel Cutter stops you from moving upward when a gimmick is above you.
- Wheel Cutter does not climb up objects when they are resting on an Astro Gate button.
- Wheel Cutter stops you riding up when under a Foot Holder.
- If multiple Spring Men are placed in a level, they will fail to perform their jumps correctly and get stuck in walls.
- When freezing a Fire Wall with Flash Stopper, then scrolling the screen, the Fire Wall does not move along with the camera.
- If Fire Wall kills a boss while they are in their intro animation, the game crashes.
- The Moving Elevator Vertical Stop would be drawn over tiles if the game spawned them in a certain order.
- Descriptions for Wily Ladder 27 and 28 are swapped.
- Magma Beam Generators placed on a top of the screen will play their sfx on the above non connected screen.
- Water Shield absorbing Astro Man's projectiles can crash the game.
- Bokazurah directly placed on springs will crash the game when played.
- Bounce Man performing his ground pound when the player is dead causes the game to crash.

Due to MM3 Wily 2 BG 2 being read as an undefined background, Luigi launched 220.127.116.11 to fix that tile. When announcing it, he apologized.
- MM3 Wily 2 BG is broken from 1.6.1.
