# PristonTale EU for Linux

Version 1.1.1 installs, updates, repairs, and launches PristonTale EU through a
native Linux dashboard. Game files come directly from the publisher and are not
included in this archive.

## Install

Keep the archive, detached signature, checksum, and
`launcher-update-public.pem` together. First confirm the public-key fingerprint
through an independent trusted channel; the expected DER SHA-256 fingerprint is
`3ae6e8dc483b93796b32e3ca270c367d247caf8d047eb796826c8e558a4a9e34`.
Then run:

```text
openssl pkey -pubin -in launcher-update-public.pem -outform DER | sha256sum
openssl dgst -sha256 -verify launcher-update-public.pem \
  -signature pristontale-eu-linux-installer-v1-1-1.tar.gz.sig \
  pristontale-eu-linux-installer-v1-1-1.tar.gz
sha256sum -c pristontale-eu-linux-installer-v1-1-1.tar.gz.sha256
tar -xzf pristontale-eu-linux-installer-v1-1-1.tar.gz
cd pristontale-eu-linux-installer-v1-1-1
./install.sh
```

The default installation directory is `~/Games/PristontaleEU`. To use another
disk or directory:

```text
./install.sh --install-dir "/path/to/PristontaleEU"
```

Existing installations at the previous default location are preserved during
upgrades. The installer adds **PristonTale EU** to the application menu and
installs the `pristontale-eu` command in `~/.local/bin`.

GE-Proton through the managed UMU helper is the default runtime for the current
game, with modern WoW64 and a separate compatibility prefix. Existing settings
switch to GE-Proton once on startup; users can choose another runtime afterwards.
Renderer preferences and saved Proton paths are retained. PTR continues to use
Proton 7.0. Proton 7.0 is discovered in both
the default Steam library and secondary libraries registered with Steam. For an
unregistered manual layout, select its exact `proton` script under
**Settings → Optional Overrides**. Use the renderer setting to choose DXVK or
WineD3D; environment assignments do not belong in the Proton script path.

## Use

Open **PristonTale EU** from the application menu or run:

```text
pristontale-eu gui
```

The main launcher button automatically shows **Install**, **Update**, or
**Play** according to the managed game's state.
