Game Builder Garage -0100fa5010788800--v131072-... [SIMPLE 2026]

Released by Nintendo EPD in June 2021, Game Builder Garage is a visual programming game that teaches users how to design their own video games using a node-based system called Nodon. Unlike traditional coding, Nodon represent variables, inputs, outputs, and game logic as colorful creatures you wire together on a grid.

The string 0100FA5010788800 is the Title ID for the US/Europe region of the game. This ID is critical for save data management, modding, or using save editors on hacked consoles. The trailing v131072 is likely a misinterpreted software version—actual latest patch is v1.1.0 (which in Nintendo’s internal indexing corresponds to v131072 if treated as a 0x20000 step; 1.0.0 = 65536, 1.1.0 = 131072).

The homebrew community has reverse-engineered the save format:

The guide covers:

Published: October 2023
Version Coverage: v1.0.0 to v1.1.0 (Nintendo Switch)
Title ID: 0100FA5010788800

Lessons 1–7 teach you:

v1.1.0 added lessons 8-10: 8. Constant & Map – Smooth movement curves. 9. Option & Wormhole – Multiple levels. 10. 3D, Friction, Rotation – First-person prototype.

Nodon are color‑coded:

| Color | Type | Example | |-------|---------------------|-----------------------------| | Red | Input | Joy‑Con stick, button press | | Blue | Output | Display text, play sound | | Green | Object | Person, box, goal | | Yellow| Calculation/Math | Addition, comparison | | Pink | Variable/Memory | Counter, constant | | Purple| Logic/Gates | AND, OR, NOT, timer | | Orange| Senses/World | Touch sensor, location | | Gray | Other | Camera, connector |

Each Nodon has input ports (left side) and output ports (right side).
You connect outputs → inputs by dragging a wire.

Key concept: Everything runs at 60 frames per second. The “game loop” is all Nodon updating in an order you can adjust (priority).
