Submission Requirements

CFW Tests

Ensure your game has been tested on all major CFWs:

• ArkOS
• AmberELEC
• ROCKNIX
• muOS
• Knulli
• Crossmix (Optional)
• Other (add here)

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

Before submitting, check your launch script against a few recently merged ports of a similar type.
If your script is significantly longer that or does over complicate things that don't appear in any merged port, remove that logic unless you can point to a game-specific reason it's needed.
Reviewers will ask why non-standard logic is there.
