Game Information

• New Port for: The Swapper
• URL: https://store.steampowered.com/app/231160/The_Swapper/

Authorship & Testing

• I wrote and understand this script/patch myself, or clearly marked which parts came from an AI assistant and reviewed them
• I can explain every non-standard line in my launch script

Submission Requirements

CFW Tests

Ensure your game has been tested on all major CFWs:

• ArkOS (R36S / RK3326 not supported)
• AmberELEC
• ROCKNIX
• muOS
• Knulli
• Crossmix (Optional)
• Other: dArkOS (R36S / RK3326 not supported)

Resolution Tests

Test all major resolutions:

• 480x320 (Optional)
• 640x480
• 720x720 (RGB30) (Optional)
• Higher resolutions (e.g., 1280x720)

File Structure

• Your port should have the following structure:
  • portname/
    • port.json
    • README.md
    • screenshot.png
    • cover.png
    • gameinfo.xml
    • Port Name.sh
    • portname/

Script Conventions

The non standard parts are:

• First-launch patcher: ASTC texture compression + normal-map downscaling to fit GPU memory budget on 1GB devices. Uses PortMaster's fancy patcher UI (utils/patcher.txt).
• ASTC runtime hook (libtexture_astc.so via LD_PRELOAD): intercepts glTexImage2D at runtime to substitute pre-compressed ASTC textures to reduce VRAM usage.
• FMOD compatibility layer (libfmodex.so): translates FMOD audio calls to SDL_mixer, including streaming for large audio assets.
• Steam shim (libsteam_api.so): reports Steam as unavailable. Does not emulate Steam, bypass ownership, or decrypt tickets.
• MONO_MANAGED_WATCHER=1: required to prevent a Mono FileSystemWatcher infinite-recursion crash on Linux.
• gl4es: bundled in gl4es.aarch64/ and loaded via SDL_VIDEO_GL_DRIVER. The game's engine requires desktop GL version strings that GLES-only devices don't provide.
