The Ultimate Guide to Managing PS2 Saves on Android Managing PlayStation 2 save files on Android is a common hurdle for retro gaming enthusiasts using emulators like AetherSX2 or NetherSX2. While the original PS2 Save Builder is a legacy Windows application, you can still use its core functions on mobile to convert, import, and build save files for your favorite classic games. What is PS2 Save Builder?

Convert to Raw: Open your save file in the builder, select all files inside, right-click, and choose Extract to a folder. This folder (the "Raw" save) is what most Android tools use. Import to Android Emulator:

  1. Open the PSV Exporter/Importer app.
  2. Tap "Import Save" (or sometimes just a "+" button).
  3. Navigate to your Downloads folder and select your save file (e.g., MGS3.cbs).
  4. The app will process the file and create a folder structure.
  5. You will see a list of files inside the save. Tap "Export to PSV".
  6. Name the file and save it. You now have a .psv file.
  1. Extract a save from AetherSX2 (memcard folder)
  2. Edit saves on Android using a hex editor (e.g., Hex Editor MD)
  3. Rebuild checksums — PS2 saves require correct CRC; without PC tools, this fails
  4. Better approach: Use Winlator (Windows emulator for Android) to run PS2 Save Builder (PC version) — heavy but possible on flagship phones
  1. Upload your .cbs or .max file.
  2. Convert it to a Memory Card Image (.bin) or .psv.
  3. Download the converted file.
