A 3DS homebrew application that randomly selects, displays and then launches an installed game from the SD card. It scans installed titles, filters out system applications, and picks a random game to launch.  
Can't decide what to play? Let your 3DS pick a random installed title and launch it.


The title database contains 4,135+ 3DS game entries with title IDs and names, sourced from the [https://3dsdb.com/ 3dsdb community database].
The offline catalog in <code>source/title_database.c</code> maps title IDs to display names (8,700+ entries).


Originally created by [https://github.com/einso einso] as a proof-of-concept, it was later expanded by selloa with improved error handling, title filtering, and additional features. The project uses code from the [https://github.com/devkitPro/3ds-examples/blob/master/app_launch/source/main.c devkitPro 3ds-examples app_launch template].

Can't decide what to play? Let your 3DS pick a random installed title and launch it.

The offline catalog in source/title_database.c maps title IDs to display names (8,700+ entries).

Originally created by einso as a proof-of-concept, this fork adds SMDH title resolution, filtering, persistent settings, and a rebuilt offline catalog. The project uses code from the devkitPro 3ds-examples app_launch template.
