A Sm64 Color Code Generator streamlines the modding process and helps you make visuals that read correctly in the game’s limited color space. Whether you’re re-skinning Mario, making HUD tweaks, or designing whole new levels, using a generator saves time and avoids surprises when your colors hit the emulator’s renderer.

Open your SM64 ROM in a tool like Toad’s Tool 64 or Mario Builder 64 .

. It bridges the gap between complex hex editing and creative design, making character customization accessible to the average user. No coding knowledge required.

Decide what you want to recolor. Mario’s overalls (blue), his shirt (red), his skin, or his cap. In the SM64 decompilation source code, these are often found in src/game/geo_mario.c or texture files.
