Moving a save between Repentance and Repentance+
Repentance+ is a free DLC released on 18 November 2024 that requires every previous DLC. It keeps its own save files, separate from Repentance, and it copies your Repentance progress exactly once. Most “my save did not transfer” threads come from that one detail.
One import, at first launch
The REPENTOGON team documents it plainly: Repentance+ only imports your save data from Repentance the first time you ever launch Repentance+. After that the rep_ and rep+ files live separate lives. If you opened Repentance+ once in 2024, went back to Repentance and got Dead God there, Repentance+ still shows the 2024 state. Disabling the Repentance+ DLC in Steam brings the old Repentance saves back, which is why the “missing” marks reappear when people downgrade; the wiki adds that the game keeps a backup of the pre-Repentance+ saves.
Manual transfer Repentance → Repentance+
No conversion is needed: Afterbirth+, Repentance and Repentance+ share the same file header. It is a copy and a rename.
- Close the game and back up both sets of files.
- Cloud setup (
SteamCloud=1): exit Steam, open<Steam>\userdata\<AccountID>\250900\remote, delete the existingrep+persistentgamedataN.dat, copyrep_persistentgamedataN.datand rename the copy torep+persistentgamedataN.dat. Keep the slot number. - Local setup (
SteamCloud=0): copypersistentgamedataN.datfromDocuments\My Games\Binding of Isaac RepentanceintoDocuments\My Games\Binding of Isaac Repentance+. Remove any date prefix such as20250126.from the name. - Move everything out of
Documents\My Games\Binding of Isaac Repentance+\save_backups; several guides report the game restoring an old file from there. - Launch Repentance+. If Steam later shows a Cloud Conflict, choose Local Save.
REPENTOGON’s importer
With REPENTOGON installed there is a built-in tool: on the title screen press ~, open Tools → Game Options → Save Management and choose “Import from Repentance”. It only adds unlocks that are missing on one side and never removes anything; it can also export new Repentance+ unlocks back to Repentance.
Repentance+ → Repentance does not work
The game ports saves forward only. Renaming rep+ to rep_ is reported to either roll the file back to an older state or load it with marks missing. Repentance also has no room for the four Repentance+ achievements (638 to 641) and the separate online marks, so those are lost in any case. What remains: Alt+F2 in Stats → Secrets, which restores secrets from your Steam achievements but not marks, stats, bestiary or challenge progress; REPENTOGON’s exporter; or a third-party converter.
Older editions and consoles
- Afterbirth+ → Repentance: Repentance imported the Afterbirth+ save automatically at first launch in 2021; the manual route is the same rename,
abp_torep_, with Steam closed. - Rebirth → Afterbirth(+): the save select screen had an “Import Rebirth” option.
- Console ↔ PC: there is no cross-save, and Nicalis has never announced one. A console-only Repentance+ Online release for PS5, Xbox Series and Switch 2 is dated 19 November 2026 by the press, and it has no relation to PC files.
