Renpy Save Editor ^hot^

Editing your progress in a visual novel can be a game-changer, whether you're a player looking to skip the grind or a developer testing specific story branches

  • Creating saves representing edge-case states to reproduce bugs.
  • Quickly toggling flags (e.g., unlocked achievements, skipped branches) for regression tests.
  • Batch generation of saves to test save/load performance.
  • Implement a sandboxed unpickler that forbids object construction beyond a safe whitelist.
  • Parse serialized data into a neutral representation (e.g., primitives, lists, dicts) without executing arbitrary reduce-style constructors.
  • Use dedicated parsers for Ren'Py’s own serialization format if available in the target version.

  • Step 1: Locate saves in standard directories (platform-specific) and list candidate files.
  • Step 2: For each file, attempt to decompress (zlib) and parse header metadata (timestamp, thumbnail). If fails, present as unparseable.
  • Step 3: Deserialize state using a safe reader that:
