Project Avalanche — native PC port of SSX (2012), test build f473368958149fda97af0de208ca48915e37e6d8

1. Start ./project-avalanche (keep avalanche-game, avalanche-movie and the fonts folder in
   the same folder: the game, which the launcher starts; the movie decoder, which the game
   starts in a sandbox of its own for a mod's movie; the fonts, which both draw names and
   chat in other scripts with).
2. Click the large SET UP GAME DATA tile, select your own SSX (2012) Xbox 360 ISO once
   and click Extract game data; the launcher unpacks the game data (about 4.7 GB) into
   ~/.local/share/project-avalanche/GameData ($XDG_DATA_HOME/project-avalanche;
   PROJECT_AVALANCHE_HOME overrides it).
3. Click the large PLAY SSX (2012) tile. The game starts in its own window. Progress is
   saved to ~/.local/share/project-avalanche/Saves/ssxvprofile.

Needs: a GPU with a Vulkan driver, ALSA for sound (PipeWire and PulseAudio provide it),
Wayland or X11, and the XDG desktop portal for the ISO file picker. Built on Ubuntu 24.04
(x86-64): it runs on distributions with that glibc or newer.

Controls: an Xbox-style gamepad with the game's own layout (recommended), or the keyboard.
  In the menus:    Enter = START, Space = A, Backspace = B, X, Y, arrow keys = D-pad,
                   Q / E = LB / RB, W A S D = left stick (the globe), F1 skips a movie.
  On the mountain: arrow keys or W A S D = left stick (steer, tuck, brake), Space = A (jump),
                   I / J / L / K = Y / X / B / A, Shift = RT, Ctrl = LT, E = RB,
                   Backspace = LB (rewind), Esc = START (pause).

HOST starts a multiplayer server on this computer (avalanche-server, next to the launcher; its licences
are THIRD_PARTY_NOTICES-server.txt) and joins it with the game.

If a start fails, its output is shown under Extras, Output and kept in
~/.local/share/project-avalanche/game.log.

No game data is included in this download.
