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

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.

The offline catalog in source/title_database.c enables filtering of homebrew apps against official title IDs (8,700+ entries).

Features

Picks a random eligible title from your library and launches it.
Shows a readable name (from the title's SMDH icon).
Reroll as many times as you like before launching.
Press SELECT for detailed filter options
Filter what can be picked: native apps, Virtual Console, DSiWare, demos, DLC, patches, system titles, and more.
Scan SD card and/or NAND (both configurable).
Unlisted only / Homebrew only mode for homebrew and titles not in the database.
Options saved to SD - your filters and preferences persist between sessions.
While viewing a pick, use L/R to page through game, detail, and technical info screens.

Installation

Via Universal Updater

Open Universal-Updater 3DS on your 3DS.
Search for "3DS Random Game Launcher".
Install the CIA (Home Menu icon) or 3DSX (Homebrew Launcher).

Manual installation (3dsx)

Download the latest .3dsx file from the Releases page.
Copy the .3dsx file to the /3ds/ folder on the SD card.
Launch from the Homebrew Launcher.

Manual installation (CIA)

Install using FBI, Universal Updater, or another CIA installer.
Launch from the 3DS Home Screen.

In the options menu: Up/Down to move, A to toggle or restore defaults, B or SELECT to close (saves settings).
