Summertime Saga Save Compatibility Checker

A community-maintained documentation project for the Summertime Saga Save Compatibility Checker.

This repository contains the compatibility rules, structured datasets, and supporting documentation used by the Save Compatibility Checker available on SummersagaHub. Its purpose is to help players understand whether updating between supported game versions may affect their existing save files.

The repository is intended to be transparent, easy to maintain, and simple to extend as new game versions become available.

Note: SummersagaHub is an independent informational website and is not affiliated with or endorsed by the developers of Summertime Saga.

Compatibility Results

Each version comparison returns one of the following outcomes.

Status	Description
Fully Compatible	Saves are generally expected to continue working between the selected versions.
Partially Compatible	Saves may work, but additional precautions or testing are recommended.
New Game Required	Existing saves are not recommended for the selected update path.
Unsupported Version	There is not enough documented information to determine compatibility.

Compatibility guidance is based on documented version changes and publicly available information about game updates.

How Compatibility Is Evaluated

The Save Compatibility Checker compares:

• Your current game version
• The version you plan to update to
• Known compatibility information between those versions

Some updates only introduce additional content and remain compatible with existing saves. Others modify story progression, internal variables, or game logic in ways that may affect older saves.

Because save behavior can vary depending on update history, installation method, and mod usage, compatibility guidance should be treated as a reference rather than a guarantee.

Creating a backup before updating is always recommended.

---

Data Format

Compatibility information is stored as structured JSON for readability and future maintenance.

Example:

{
  "currentVersion": "0.20.16",
  "targetVersion": "0.20.17",
  "status": "Fully Compatible",
  "reason": "No documented compatibility issues between these versions."
}
