Cthulhu

Cthulhu is a 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.

Current Features:

Clear play time history: clears your play time history (it can be seen at Activity Log under "Daily Records").
Clear step history: clears your step history (it can be seen at Activity Log under "Daily Records").
Clear software library: clears your software library (it can be seen at Activity Log under "Software Library").
Edit software library: allows editing of individual entries on your software library.
Clear shared icon cache: clear all shared cached icon data, used by Activity Log, Friends List and Notifications (this will also clear your Activity Log title list).
Update shared icon cache: iterates through all entries and replaces outdated ones.
Restore shared icon cache: restores the previous shared icon cache in case something goes wrong while updating it.
Clear HOME Menu icon cache: clears the icon cache used by HOME Menu, then reboots the console so HOME Menu can create it again.
Update HOME Menu icon cache: iterates through all entries and replaces outdated ones.
Restore HOME Menu icon cache: restores the previous HOME Menu icon cache in case something goes wrong while updating it.
Reset demo play count: resets the play count of all installed demo software.
Reset folder count: resets HOME Menu's folder count so that the next folder created is "1". (Only works if you run Cthulhu from Test Menu).
Unwrap all HOME Menu software: unpacks all gift-wrapped software on HOME Menu.
Repack all HOME Menu software: gift-wraps all software on HOME Menu. Mainly intended for testing the above feature.
Remove software update nag: installed titles will no longer ask for an update when launched (until HOME Menu downloads version data again). This can't be used to bypass the hardcoded version check on "Ironfall: Invasion".
Clear game notes: clear all of your game notes.
Replace eShop BGM: replaces the current eShop music with a custom one.
Restore eShop BGM: restores the default current eShop music.
Change accepted EULA version: useful for allowing out-of-region online play (when set to FF.FF).
Toggle HOME/Test menu: changes which menu the 3DS will boot on startup (Test Menu needs UNITINFO patch AND having test menu installed for it to work).
Set play coin count to 300.

Future Features:

Misc. features seen on dev unit software.

Obs.:

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).
