Linux-3DS.nix

What's this??

This is a Nix-based packaging for linux-3ds, a port of Linux for the 3DS family of devices.

For the time being, and for the foreseeable future, this is only mean to build a toy system (kernel and initramfs) as a demo. This is a neat showcase of how one can leverage Nixpkgs and Nix in parts to build an embedded style system.

This has no real use.

How do I use this?

Generally speaking, you probably wouldn't. Additionally, this does not list the steps required for hacking your 3DS. I'm assuming luma is the payload used and already installed.

If you want to, still, first build sdcard-filesystem, which is the partial skeleton structure to copy to your SD card,

 $ env -i nix-build -A sdcard-filesystem

And somehow copy this to your SD card. (Read the tips section.)

Then, when the 3DS boots, holds [START]. This will show the Luma3DS chainloader interface. Select firm_linux_loader and launch it.

The display will glitch out a bit for a few seconds, then the top panel will show the console logs, and the bottom panel a basic on-screen-keyboard.

Have fun!

Tips

Easier rebooting from 3DS menu

Hold [L] + [SELECT] then press [DPAD Down]

Then you can choose Reboot and hold [START].

Copying result

Use ./ftp.sh <ip address:port> to copy to your 3DS, assuming it is running an FTP server.
