Get PetPal onto your 3DS.

PetPal is homebrew, so you'll need a 3DS with the Homebrew Launcher. Build the app, drop it on your SD card, and you're passing in minutes.

Compatibility

Works on every 3DS & 2DS

Old or New, regular or XL — if it runs homebrew, it runs PetPal. Targets Old 3DS, New 3DS, and New 3DS XL.

Compatibility chart showing all six Nintendo handheld models — original 3DS, 3DS XL, 2DS, New 3DS, New 3DS XL, and New 2DS XL — each marked with a green check.
All six models in the 3DS family are supported.

Quick start

Build the 3DS app

You'll need devkitPro with the 3ds-dev group installed (libctru, citro2d, citro3d, and tools).

# install the toolchain group
pacman -S 3ds-dev

# build — produces PetPal.3dsx (+ .smdh)
make

Copy PetPal.3dsx to sdmc:/3ds/ and launch it from the Homebrew Launcher — or run it over the network with 3dslink PetPal.3dsx.

Where your save lives

save.bin
your pet, friends, and journal
save.bak
a rotating backup, written automatically
backups/
portable exports you can copy off-device

All of it sits under sdmc:/3ds/PetPal/, created for you on first launch.

For tinkerers

Run the model tests on your PC

The gameplay, save, and NetPass logic is decoupled from the device, so the whole model layer compiles and runs on a desktop — no 3DS required.
