ZIP Package Checklist

Use this checklist before uploading a multi-file game bundle to RetiPie Slice.

Required structure

Your ZIP must contain an index.html file at the root, or inside one shared root folder that RetiPie can strip during extraction.

game.zip
  index.html
  main.js
  style.css
  assets/
    player.png

This also works:

game.zip
  my-game/
    index.html
    main.js
    assets/
      player.png

Before upload

• Bundle images, audio, fonts, data files, and scripts inside the ZIP.
• Use relative asset paths so files resolve after extraction.
• Remove build folders that are not needed at runtime.
• Avoid third-party ad SDKs, analytics scripts, pixels, or tag managers.
• Keep the file names your game references. RetiPie stores them as they are; names containing .., a backslash, or a control character are rejected.
• Leave out executables, other interpreters' scripts, app packages, and nested archives. See File types.
• For engine exports, follow the Unity or Godot guide.

macOS metadata

Finder can add __MACOSX metadata folders. RetiPie filters these during extraction, but removing them before upload keeps the archive easier to inspect.

Validation

RetiPie checks blocked file types, executable content, file names and path length, extracted size and decompression ratio, maximum file count, and ad or tracking patterns before a release becomes active.
