File Filtering

Section titled “File Filtering”

By default, Spark filters the file picker to show only supported formats. If your game file doesn’t appear when importing:

  1. Go to Settings > Game Library
  2. Disable File Extension Filter
  3. Try importing again

This is especially useful for APK files, which may be filtered by iOS.

Game Structure

Section titled “Game Structure”

After extraction, Spark expects the standard Ren’Py directory structure:

GameName/
  game/
    script.rpy
    scripts.rpa
    ...
  renpy/
  lib/

Spark automatically detects the game root within the archive and extracts it correctly, even if the archive contains extra wrapper directories.

APK Import Details

Section titled “APK Import Details”

When importing an Android APK:

  1. Spark extracts the APK (it’s a ZIP file)
  2. Locates the Ren’Py game data inside the assets/ directory
  3. Determines the game name from the Android manifest, gamename.py, or the archive filename
  4. Copies the game files to the correct directory structure
