A release group known for packaging games into standalone, portable directories. Their releases typically include:

Wine translates Windows API calls into POSIX calls. For Geometry Dash 2.2, the primary challenges are:

Even with the JC141 free package, you may encounter bugs. Here is the symptom-to-solution table.

| Symptom | Likely Cause | JC141-Specific Fix | | :--- | :--- | :--- | | Black screen on startup | DXVK missing or Vulkan not supported | Edit start.sh, add export DXVK_FILTER_DEVICE_NAME=INTEL (or AMD/NVIDIA). Or set PROTON_USE_WINED3D=1. | | No sound / Crackling audio | PulseAudio buffer mismatch | Install pulseaudio-utils and run pasuspender -- ./start.sh | | Game runs at 30 FPS | Compositor vsync interference | In your DE (GNOME/KDE), disable "Allow Tearing" or use export vblank_mode=0 before the wine command. | | Crashes when entering Platformer mode | Missing d3dx9_43 | JC141 script should include WINEDLLOVERRIDES="d3dx9_43=n,b". If not, manually set in winecfg. | | Text is garbled (boxes instead of letters) | Missing Core fonts | winetricks corefonts inside the prefix directory. |

JC141 uses high compression (7z or rar). Extract using:

7z x Geometry.Dash.2.2.7z -o~/Games/

Or, if using unrar:

unrar x Geometry.Dash.2.2.rar ~/Games/

This creates a portable directory, e.g., ~/Games/Geometry Dash 2.2/.

While Geometry Dash is light on text, the Eng tag assures that the language files are set to English by default, avoiding any locale-based crashes that sometimes plague Wine prefixes.
