Cthulhu is a 3DS homebrew application for managing play time history, step history and cached icon data.

The goal of this app is to provide an open-source alternative to some of the 3DS Development Unit Software, alongside with extra features.

Features

  • Clear play time history.
  • Clear step history.
  • Clear and/or edit software library.
  • Clear, update and/or restore shared icon cache.
  • Clear, update and/or restore Home Menu icon cache.
  • Reset demo play count.
  • Reset folder count.
  • Unwrap and/or repack all Home Menu software at once.
  • Remove software update notifications (with exceptions).
  • Clear game notes.
  • Replace and/or restore eShop BGM.
  • Change accepted EULA version for allowing out-of-region online play.
  • Toggle Home Menu/Test Menu on startup (requires UNITINFO patch and Test Menu installed).
  • Set play coin count to 300.

Installation

Available as a 3DSX (latest) and CIA.

  • 3DSX - Copy .3dsx to sdmc:/3ds/Cthulhu then run with homebrew launcher.
  • CIA - Install .cia with the CIA manager of your choice.

Notes from developer:

It is recommendeded to use the 3DSX version with Luma3DS 9.0. Work just as fine as the CIA (available in v1.3.4 and prior releases) and without cluttering your activity log.

Also always make a backup of your activity log savefile before using software library features.

Known issues

Because Home Menu doesn't allow accessing its icon cache while it's running, Cthulhu runs on extended memory mode.

Clearing or updating Home Menu icon cache may uninstall sdiconhax (a.k.a menuhax 3.x).
