BootCTR9 is an ARM9 bootloader for the 3DS System. It's based on BootCTR and its configuration, but with some additional features.

It's for arm9loaderhax users only, but it should be possible to load it with any arm9payload loader, that allows the loading a payload from offset 0x0.

Features

• Boot ARM9 payloads (.dat and .bin).
• Setting a delay to be able to press the payloads button after powering the 3DS on.
• Setting a boot delay, between the selection of the payload and running it, which allows to press the button combinations for the payload.
• Enabling and disabling of the screen.
• Setting the screen brightness for BootCTR9 and the payloads.
• Show splashscreens.
• Show bootanimations (based on BootAnim9).
• Detect softboots and skip the payload selection and splashscreen.
• Path the payloads path in it's binary (currently only needed in LumaCFW).
