ROM hacking tool for Pokémon Mystery Dungeon Explorers of Sky.
It is available for Linux, macOS and Windows.
It includes a Python library for editing the ROM through Python (skytemple-files) and a debugger / script editor is integrated into the UI of SkyTemple (skytemple-ssb-debugger). Inside the debugger you can edit the game's scripts via the programming language ExplorerScript.
See the Project Pokémon forums page.
To download SkyTemple for Windows and macOS head over to the download page or Project Pokémon.
If you want to set up SkyTemple for development, see the "BUILDING_WINDOWS.md" or "BUILDING_MACOS.md" file.
SkyTemple is distributed as a Flatpak on Flathub for all major Linux distributions.
This Flatpak contains everything needed to use all SkyTemple features.
Source repository for the Flatpak: https://github.com/flathub/org.skytemple.SkyTemple
The Linux version can be installed manually/"natively" via Pip.
For this Python 3.9+ must be installed and GTK+ 3
(which you most likely both have). Additionally GtkSourceView 4 is required
(package gtksourceview4 on Arch and libgtksourceview-4-dev on Ubuntu).
Then install SkyTemple via pip:
pip install --upgrade skytemple[eventserver,discord]
You may need to run pip3 instead and/or need to update pip by running:
pip3 install --upgrade pip
After this, you can run skytemple to run it.
If this doesn't work, you don't have ~/.local/bin in your PATH.
Run ~/.local/bin/skytemple instead.
To be able to apply patches, you need to install armips. Sadly they don't provide builds. However for Arch Linux a version is available through the AUR.
If you want to set up SkyTemple for development, clone the repos and install in editable mode instead. See the steps 7 and onward in "BUILDING_WINDOWS.md".
