Online editor

Mr. Mine

Edit the game’s Base64 export in your browser (same string you import in-game). Field labels and Δ vs your first load — not a from-scratch save generator. Mapping is tuned for ~V44-era exports; V46+ compatibility is still being tested.

No persistent storage of your saves on our servers — editing stays local in your browser when possible.

Online editor

Paste one full line from the game (Settings → export) or from Steam SaveBackup.txt. Parsing and patching run in your browser — we do not upload your save.

Mr. Mine — exported save editor

Double–Base64, pipe-separated export. Labels come from data files (Chinese/English). Numeric fields show Δ vs your first load; long segments are in Advanced. Indices are verified against ~V44 sample exports; newer builds (e.g. V46) may shift fields — compatibility is not yet fully verified.

Exported save string

Paste one export per load. If you paste several lines, only the first line is used. Prefer Settings → export in the game, or copy from SaveBackup.txt.

Quick FAQ

Common questions about the export line, clipboard import, and version differences for Mr. Mine.

Why paste a text line instead of picking a .save file?: Mr. Mine’s flow is Settings → export / import: one line `SaveName|Base64…` (double Base64, pipe-separated). This editor reads and writes that same line — not arbitrary binary files.
Can I use Steam’s SaveBackup.txt?: Yes. Copy one full line from SaveBackup.txt or use the in-game export — same format. Paste only one line per edit session.
The editor says my file is JSON and isn’t supported.: The tool expects the game’s Base64 export line. If you only have JSON from elsewhere, use the in-game export or a line from SaveBackup.txt instead.
Some labels or values look wrong after a game update.: Field mapping targets ~V44-era exports; big patches (e.g. V46+) can add or shift pipe fields. Export fresh from your build, compare carefully, and keep backups.
