手順とヒント(Base64)
使い方
- Back up the original file. The tool expects the file content to be Base64 text (UTF-8 or Latin-1); whitespace is ignored.
- After upload, the inner payload is decoded. If it is JSON, you get the same path-based editor as the JSON tool; if it is binary, you get a hex grid on the decoded bytes.
- Edit values, then download. The output file is UTF-8 text containing a new Base64 string representing the updated payload (not necessarily identical padding to the original).
- Replace the game file only after verifying size/encoding expectations for that title.
制限事項
- Decoding tries UTF-8 first, then Latin-1 byte mapping — useful when the file is ASCII-only Base64 without a BOM.
- If decode fails, the content is not valid Base64 for this parser — use the hex tool on the raw file instead.
- Inner JSON that is not UTF-8 may mis-parse; binary inner content always falls back to hex.
- Cryptographic signatures or hashes on the outer file are not updated — the game may refuse to load modified saves.
