[Guide] How to Unlock Debug & Developer Menu – Sonic Mania

In this guide, you’ll learn how to unlock debug & developer mode in Sonic Mania by step by step.

Developer Mode

Get into Sonic Mania’s developer menu.

Locate Sonic Mania in the Game Library.
Right-click it, and navigate to Manage > Browse local files to go to Sonic Mania installation folder.
A file called Settings.ini can be found in this folder. Open it with any text editor (If you couldn’t find that file, relaunch Sonic Mania and check again).
Look for the line that starts with “[Game]“.
When you find it, go to next line and add “devMenu=y” code.
Save the file.
Launch Sonic Mania.

Now you can open Developer Mode by clicking the Escape.

Go back to Developer menu.
Select a level by going to Stage Select > Presentation > Level Select.
Press Q key from the keyboard to enter Sonic Mania debug mode (I assume that you have selected the level).

Developer mode and Debug mode are unlocked now 🙂
