Every game on the Nintendo Switch is assigned a unique Title ID, a 16-character hexadecimal string. For Super Mario Maker 2, the ID is:
01009B90006DC800
Let’s dissect it:
| Section | Value | Meaning |
|---------|-------|---------|
| Title type prefix | 0100 | Indicates a full commercial game (not a demo, DLC, or update). |
| Developer code | 9B9 | Internal Nintendo code for the game’s publisher (Nintendo EPD). |
| Game code | 0006DC8 | Unique identifier for Super Mario Maker 2. |
| Region/version suffix | 00 | Base game region (00 typically means worldwide/all regions). | Super Mario Maker 2 -01009B90006DC800--v393216-...
Why does this matter? If you were to extract save data, mod the game, or use an emulator like Ryujinx or Yuzu, the Title ID tells the system exactly which game the data belongs to. Even DLC and updates have their own derivative IDs (e.g., 01009B90006DC801 for update data).
In the string you provided, 01009B90006DC800 appears right after the game name, confirming this refers to the base game cartridge or digital version, not a patch or add-on.

At first glance, it looks like a random assortment of numbers and letters. But to dataminers, speedrunners, modders, and digital archivists, this sequence is a precise fingerprint of one of the most creative games ever released on the Switch. This article breaks down each component—from the Title ID to the version encoding—and explores why such details matter beyond the launch screen. The interesting part: This indicates the file belongs
The v393216 part is fascinating from a data perspective. It looks like a random large number, but it is actually a calculation of the game's update version.
The interesting part: This indicates the file belongs to Version 1.6.0 (or update version 6). This was a significant update for Super Mario Maker 2 (released around April 2020) because it introduced the World Maker feature, allowing players to create entire world maps rather than just standalone levels. That string represents a pivotal moment in the game's lifecycle.
