The input system uses hardware scan codes to map buttons. While modern builds include robust in-game controller configuration menus, the text file reveals exact button IDs.
Even experienced users encounter issues. Here are the most common pitfalls:
: One of the most common settings you will see. Setting this to true switches the controller layout from the default scheme (A/X for jumping, B/Y for attacking) to the original Nintendo 64 layout (A/B for jumping, X/Y for attacking).
: If you experience audio crackling, the game might be running above 30 FPS. The recommended fix is to cap the frame rate at 30 FPS, which can be adjusted in the config file. sm64config.txt
The sm64config.txt file is a plain text document generated by the Super Mario 64 PC port upon its first launch. It stores your user preferences, graphics settings, audio configurations, and custom controller mappings.
If your Jump and Attack buttons feel backwards, look for button_a and button_b and swap their assigned letters (e.g., change button_a B to button_a A ).

The Super Mario 64 PC port community continues to grow, with forks like Coop Deluxe introducing online multiplayer, Render96ex delivering stunning graphical overhauls, and the original sm64ex providing the stable foundation upon which all this innovation rests. Through it all, sm64config.txt remains the that bridges the gap between your preferences and the game's engine.

While not a dealbreaker, it introduces a trial-and-error loop (change setting -> save -> launch game -> realize the resolution is wrong -> close game -> edit file) that a built-in GUI options menu would solve. Thankfully, many modern builds now offer an in-game menu that writes to this file automatically, mitigating this issue.
: Controls the sharpness of textures, with 1 often representing standard linear filtering. Audio Levels
: Inputs are represented by numerical scan codes. For example, key_a 57 might correspond to the Spacebar.
