Rosalina - Hacks Guide Wiki (2024)

This article is about Rosalina, accessible when booted into the HOME Menu. For information about the Luma3DS configuration menu (accessible by holding SELECT on boot), see this page.

Rosalina is a system module for Luma3DS that can be accessed while your 3DS is powered on and in 3DS mode by pressing a keycombo specified in the file sd:/luma/config.ini. By default, the keycombo is L + + Select.

Rosalina is not accessible from within payloads (such as GodMode9), from DS/DSi mode (such as when using a DS cartridge or when using TWiLightMenu++), or from GBA mode (such as when using GBA virtual console).

This menu offers many options for real-time configuration of the system, including but not limited to the following:

  • Take screenshots
  • Change system settings such as brightness, active cheats, wireless status, and (on New 3DS/2DS only) clock speed & L2 cache
  • Activate a blue light filter

Our custom firmware installation guide uses the Rosalina menu for multiple functions. This page will contain explanations for all the options and information present in the Rosalina menu to enable easier navigation and usage.

Opening and navigating the Rosalina Menu

Rosalina - Hacks Guide Wiki (1)If your L, D-Pad Down, or Select keys are broken, you will not be able to open the Rosalina menu by default. To fix this, modify the sd:/luma/config.ini file by editing the variable rosalina_menu_keycombo to two or more keys that work for you, such as X+Y. If you do not see the config.ini, update Luma3DS to version 11.0 or newer.

You can access Rosalina by pressing your chosen keycombo while in most areas of the system, excluding the following:

  • Safe Mode (can be bypassed, read Luma3DS Configuration for more details)
  • DS and GBA games, and homebrew that enters these modes (TWiLightMenu++ being a notable example)

Once in the Rosalina menu, use D-Pad Up and D-Pad Down to navigate the options. Press A to choose/enable/disable an option or view a submenu. Once in a submenu, press B to return to the main menu. The currently highlighted option is denoted by a > to the left of its text - the option highlighted when you first open the menu is Take screenshot.

While the Rosalina menu is launched, whatever is actively will pause until you exit the Rosalina menu. If you are playing a game online, this will cause your session to disconnect.

Once you are done changing options, press B until you exit Rosalina and return to the system, unpausing what is currently running.

Rosalina Options

Take Screenshot

Takes a screenshot of both screens' content and saves it to sd:/luma/screenshots as two .bmp files. Activates immediately after being pressed.

Change screen brightness

Shows the current luminance of the screen and allows you to change it with the D-Pad - D-Pad Up and D-Pad Down increment by 1, D-Pad Left and D-Pad Right increment by 10. The change in luminance takes effect instantly, including inside Rosalina. Note that any action that restarts the system or enters a place where Rosalina cannot function will reset brightness to the last chosen preset.

Cheats...

When inside a title where cheats have been selected for use (either through Checkpoint or through manually adding them to Luma, this menu shows the selected cheats. Press A on a cheat to change the ( ) to a (x), at which point they will be activated when you leave Rosalina.If the title you are currently in has no cheats selected for it, the menu will instead display No suitable title found.

Plugin Loader

When enabled, this option will allow for the use of .3GX plugins in games.

Process list

Rosalina - Hacks Guide Wiki (2)Be very careful when editing system memory, as unintended consequences may happen.

Shows a list of all system processes currently running, and allows you to view & edit their memory by pressing A on a process name.

Debugger options...

Rosalina - Hacks Guide Wiki (3)

This section is a work in progress. Notes:Information on how the debugger works.

Rosalina - Hacks Guide Wiki (4)This option can potentially cause system instability or even crashes - don't use it unless you know what you're doing and why.

Allows you to enable/disable a debugger for apps, including forcibly debugging the next application launched. Also shows the system's local IP address in Rosalina while enabled.

System configuration...

Allows you to control various elements of the system's hardware.

Control Wireless connection

Forcibly enables a connection to a chosen WiFi slot - once active, this connection will not drop unless the signal becomes unavailable until manually disabled.

Toggle LEDs

Rosalina - Hacks Guide Wiki (5)

This section is a work in progress. Notes:Make sure the list of disabled LEDs is accurate, and verify if the info regarding closing the system is actually erroneous or just bugged on one system.

When first pressed, disables the power LED and wireless LED until re-enabled manually or the system is closed while in the POWER button menu. The menu states that entering sleep mode by closing the system will always reset the LED state, but this is erroneous.

Toggle Wireless

Toggles the 3DS' ability to connect to WiFi networks. While toggled off, this stops Control Wireless connection from connecting to a slot. This setting's chosen option is saved and reapplied on next boot automatically.

Toggle power button

Toggles the power button's ability to enter the power-off menu. While toggled off, the power button can still be held for ~7 seconds to forcibly power off the system.

Toggle power to card slot

Toggles the 3DS' ability to read cartridges while active. This prevents the passive power drain from having a cartridge inserted, but requires you re-enable this setting or remove and reinsert the cartridge to be able to play it again.

Screen filters

Allows you to enable a blue-light filter with settings at certain degrees Kelvin, the default setting being 6500K and the range being from 1200K-10000K - if edited through config.ini instead, the range is 1000K-25100K. This setting's chosen option will be saved and applied on boot if you choose Save settings under Miscellaneous options... or edit it via the config.ini.

New 3DS Menu...

Rosalina - Hacks Guide Wiki (6)This option can only be used on a New 3DS/2DS.

Allows you to manually change how much CPU and L2 cache is given to the active title - this can also be changed in Luma3DS Configuration for all games. Enabling both extra clock speed and L2 cache may reveal hidden bugs in games, to unknown effect.

Miscellaneous options...

Allows for various system tweaks. Three of these, which will be noted as they appear for reference, are used on our custom firmware installation guide.

Switch the hb. title to the current app.

When inside a title, changes the active title's HOME Menu icon to open the Homebrew Launcher instead until another title is chosen or the system reboots. This is used in our custom firmware guide as a part of Finalizing Setup to access the Homebrew Launcher, though most system apps will work for this purpose and it is unneeded after the Homebrew Launcher Wrapper is installed.

Change the menu combo

Changes the keycombo used to access Rosalina. The change will not be preserved across a reboot unless you use the Save settings button.

Start InputRedirection

Starts the InputRedirection service to allow for the use of external controllers.

Update date and time via NTP

Connects to a time server to remotely sync the 3DS' date and time, after a UTC offset in the form of+0000 is chosen. The chosen time zone can be saved to Luma3DS Configuration via the Save settings option.

Nullify user time offset

Changes the embedded RTC clock to match the 3DS' current date and time (RTC + user time offset), then sets the offset to 0. This is done in our custom firmware guide as a part of Finalizing Setup.

Dump DSP firmware

Copies the file dspfirm.cdc to sd:/3ds to allow homebrew apps to use the 3ds' audio. This is done in our custom firmware guide as a part of Finalizing Setup.

Save settings

Saves the current NTP time zone, the active screen filter, and any changes to the Rosalina keycombo to sd:/luma/config.ini.

Power off

After a confirmation, powers off your console. Note that the console takes longer to fully shut down this way compared to doing it from the POWER button menu.

Reboot

After a confirmation, reboots your console. Notably, this takes far less time than both the Power off Rosalina option and manually rebooting via the POWER button.

Credits

Displays a credits page for the creation of Luma3DS and all its contributors.

Rosalina Info

In addition to system functionality, Rosalina also displays multiple pieces of system information.At the bottom of the Rosalina menu, in order from left-to-right, the following are displayed:

  • The Luma3DS version number
  • Unlike the Luma3DS configuration menu, this will not display the full commit name for Luma3DS forks
  • The current battery temperature, in °C
  • The current battery voltage
  • The current charge percentage, displayed to the nearest 0.1%
