Jailbreaking your 3DS is not synonymous with piracy, no matter how popular it may be to do so for that end. Here's a non-exhaustive sampling of some cool things you can do with your fancy little 3D clamshell computer.
- If you've got a New 3DS (or New 2DS), here's how to play 3D (or 2D) videos at 60FPS at the 3DS' native screen resolution! https://github.com/Core-2-Extreme/Video_player_for_3DS
- Use the hardware GBA backwards-compatibility for any game, originally only available for "3DS Ambassador" titles. https://github.com/profi200/open_agb_firm
- If you're a GBA homebrew developer, setting up your 3DS with https://github.com/joshbackstein/gba-net-boot is a great way to test on GBA hardware as part of your workflow without fiddling with a flashcart and causing contact wear. (This is a godsend while iterating on timing-sensitive demoscene bullshit that's inconsistent in emulators)
- Speaking of cartridge wear, you can install your own gamecards to your internal memory so you don't have to juggle them. https://github.com/d0k3/GodMode9
- Back up your game saves! https://github.com/BernardoGiordano/Checkpoint
- Use a Gamecube/Xbox controller to play 3DS games! https://github.com/MissingNO123/GCIR
- You can target the 3DS with Rust! https://github.com/rust3ds

mods????
(these will work on legitimate copies of games; the patching is done at runtime, i.e. by redirecting I/O to the patched assets)
