A Windows and Linux x64 utility for restoring unobtainable outfits/items in supported Control Resonant saves. Version 1.4.1 restores 14 cosmetics plus the Pickpocket's Tool charm and removes their associated applied-entitlement entries.

Windows v1.4.1 was tested by the repository owner, who confirmed it works as expected on October 1, 2026, using game file version 0.564.208.5. It adds Deathadder Jacket (Razer).

Version 1.2.0 was tested and confirmed working on Windows with the then-current game version by the repository owner on September 27, 2026.

The Linux v1.2.0 version was also tested by the user who opened issue #2, who reported that the patcher ran successfully.

The downloads below are v1.4.1, available for Windows and Linux x64, with Steam, Epic .chunk, and Xbox app / Microsoft Store WGS save support. The Windows download is the exact build tested by the repository owner. Linux v1.4.1 compiled successfully; its execution, Epic/WGS in-game behavior, and cloud persistence remain unconfirmed.

• Windows: CosmeticSavePatcher.exe
• Linux x64: CosmeticSavePatcher-linux-x64 — includes .NET; no separate .NET installation or Wine needed. A Linux user reported successful execution in issue #2.

• Adds Deathadder Jacket, world-fact key 0x3EE727291BFE7B2B, and cleanup of its applied-entitlement item ID 0x48A1D491.
• Retains Steam, Epic .chunk, Xbox WGS support and whole-save backups.
• Includes full product, description, company and copyright metadata. The Windows executable remains unsigned.
• This addition is based on current installed game databases; it is not a demonstrated fix for reported map delay or launch failures.

• Adds Epic Games saves ending in .chunk, preserving physical filenames and backups.
• Rejects duplicate normalized names and requires complete save sets within each format.
• Backs up every recognized save set and preference file in the selected folder; WGS backups include every indexed container and its metadata.
• Checks the complete backup file list and hashes before applying changes.
• Retains the same 14 reward flags and existing Steam/WGS support.
• Epic in-game compatibility and cloud persistence have not yet been confirmed.

• Adds Xbox app / Microsoft Store WGS file support, contributed by hdfyeg35.
• Resolves logical save names through containers.index and container.N, retaining the existing 14-item patch logic.
• Rechecks complete metadata snapshots before writing, including patches that do not change file sizes.
• Rejects linked parent directories, duplicate blob mappings, and ambiguous GUID references.
• Backs up the four selected save blobs, containers.index, and the selected container.N with their original relative paths.

• Adds Optical Filtering Goggles, Communications Department Headset, Sierra Helmet, Sierra Vest, Sierra Suit, and MIO Specialist's Robe.
• Retains all eight previous item flags, including Exposed and the Pickpocket's Tool charm.
• Removes matching applied-entitlement markers for the added promotions and PC preorder, extending the existing revocation-prevention approach.
• Adding promotional flags alone leaves your equipped outfit unchanged; equip the items from the cosmetic menu.

To upgrade, replace the patcher with the new build for your operating system and run it beside your saves.

Reward sources are mapped from the installed game data. Corrupted is the preorder body appearance; Exposed is a separate shirtless-base flag granted by the same entitlement. Exposed is included to preserve the full preorder grant, rather than being identified here as a separately advertised bonus. Pickpocket's Tool is a charm.

1. Close the game.
2. Open your Steam save folder and put CosmeticSavePatcher.exe inside it.
3. Double-click it. It checks the files, creates a backup, and patches the newest save set.
4. Read the result, press Enter to close, then start the game and load that save.

Only the EXE is needed. No Python, installer, internet connection, or administrator access is required. It uses the .NET Framework included with Windows 10/11.

Use the v1.4.1 Windows download above. Close the game and let any ongoing synchronization finish. Keep a full copy of the WGS account folder before first use.

1. Open %LOCALAPPDATA%\Packages\ and find the game's package folder beginning with Remedy.CONTROLResonant_.
2. Open its SystemAppData\wgs\ directory, then the account folder containing containers.index.
3. Put CosmeticSavePatcher.exe directly beside containers.index.
4. Run .\CosmeticSavePatcher.exe --check to inspect the selected save, then run it normally to apply the patch.
5. Start the game and check the items. Make a normal in-game save. Cloud persistence has not yet been confirmed for this integration.

WGS discovery follows only the folders and blobs referenced by the index. It is not a recursive search. It selects the newest header and stops if that save is incomplete; it does not fall back to an older save. If both different GUID files referenced by one entry exist, the patcher stops rather than guessing which is current.

A user reported the following Windows save location:

%LOCALAPPDATA%\Remedy\CONTROLResonant\<account-id>\<slot-folder>\

Expanded form:

C:\Users\<Windows-user>\AppData\Local\Remedy\CONTROLResonant\<account-id>\<slot-folder>\

%LOCALAPPDATA% opens the current Windows user's local AppData folder. <Windows-user> is your Windows profile folder name; <account-id> is the long generated folder name inside CONTROLResonant, which differs between accounts. <slot-folder> is the save-slot folder: the reported example was slot-1. If you have several account or slot folders, choose the one containing the save you want to patch. These placeholders are not literal folder names.

Press Win+R, enter %LOCALAPPDATA%\Remedy\CONTROLResonant, and open your account folder, then slot-1 or the appropriate slot folder. Put the patcher inside that slot folder, beside the actual .chunk files. It does not search the parent account folder or subfolders.

1. Close the game and let any ongoing cloud synchronization finish.
2. Open the account and slot folder described above. Confirm that it contains matching -header.chunk, -persi-global.chunk, -player.chunk, and -bundle-container.chunk files.
3. Put the v1.4.1 patcher for your operating system beside those files. Keep the .chunk extensions and the existing --containerDisplayName.chunk file.
4. On Windows, double-click CosmeticSavePatcher.exe. On Linux, use the terminal commands in the Linux section below.
5. Read the result, then load the save in game. The newest set is chosen using the timestamp inside its header; all four matching files must be present.

The patcher backs up all .chunk files in that folder, including the container-name file, using their original filenames. To undo, close the game and follow Backups and undo. Duplicate filenames with and without .chunk are rejected. Files from the two formats are never combined into one save set.

Epic support has been implemented from the supplied saves; in-game behavior and Epic cloud persistence remain unconfirmed. Epic .chunk filename support requires v1.4.0 or later.

1. Close the game completely.
2. Open the Linux save location below and find the folder containing your save files. Download CosmeticSavePatcher-linux-x64 and put it beside those files.
3. Open a terminal in that folder and run:

chmod +x CosmeticSavePatcher-linux-x64
./CosmeticSavePatcher-linux-x64

4. Read the result and press Enter to close. Start the game normally and load the patched save.

Only this one file is needed. It includes .NET 8.0.31 and uses the same automatic backups and save selection as the Windows build. It targets x64 Linux with glibc, not ARM or Alpine/musl. The bundled runtime extracts native libraries to your user's .net cache on first launch; the save files are read from beside the patcher.

<Steam-folder>\userdata\<user-id>\3669870\remote\

• <Steam-folder> is the folder containing Steam's userdata directory, usually C:\Program Files (x86)\Steam.
• <user-id> is your Steam account's numbered folder inside userdata.

Open your Steam folder, then userdata, your numbered account folder, 3669870, and finally remote. Put CosmeticSavePatcher.exe inside that remote folder, beside the save files.

<Steam-folder>/userdata/<user-id>/3669870/remote/

<Steam-folder> is the Steam client folder containing userdata. It may be different from the Steam library where the game is installed. <user-id> is your Steam account's numbered folder inside userdata.

Open the Steam folder, then userdata, your numbered account folder, 3669870, and remote. Put CosmeticSavePatcher-linux-x64 inside remote, beside the actual save files ending in -header, -persi-global, -player, and -bundle-container. The patcher only checks its own folder and does not search subfolders.

A Linux user reported this location and successful execution of the patcher in issue #2.

The angle-bracket names above are placeholders, not text to type literally.

The patcher uses the date inside the save, not its filename number or filesystem modification date. Names can differ from the original examples, but each set must contain four files with the same prefix and these endings:

-header
-persi-global
-player
-bundle-container

Epic uses the same four endings followed by .chunk, for example auto-2-header.chunk. Keep all four files in the same format. The container display-name file is preserved.

For flat saves, keep all four together beside the patcher; subfolders are not searched. To patch a particular flat save, put just its four files and the patcher in a separate folder. Only files present beside the patcher are included in its backup; use the original save folder to back up all sets. After patching a separate copy, copy all four save files back into the original save folder before starting the game.

For WGS, these are logical filenames mapped by the index to GUID blobs. Keep the full account-folder structure intact, with the patcher beside containers.index. Both formats select the newest header and require all four matching files; they stop on ties or an incomplete newest save.

From v1.4.0 onward, before editing, the program creates a CosmeticSaveBackup-... folder containing:

• Steam: every save set in the current folder, all preferences_* files, and steam_autocloud.vdf / remotecache.vdf if present.
• Epic: every .chunk file in the current folder, including --containerDisplayName.chunk, plus any preferences and recognized Steam save files there.
• WGS: containers.index and every file in every indexed container directory, including preference containers and all container.N metadata. Original GUID paths are preserved.

Other account folders, unindexed WGS directories, patcher executables, and previous backup folders are excluded. Flat-save subfolders are not searched. An unexpected subfolder inside an indexed WGS container stops the patch. RESTORE.txt lists original paths and SHA-256 hashes. Failed backups are marked INCOMPLETE and must not be restored. The patch is applied only after the backup succeeds and the source file list and hashes have been rechecked. Only the newest save set is patched. --check and already-patched saves create no backup.

Earlier v1.3.0 backups contain only the selected save set and its WGS metadata.

To undo, close the game and let cloud synchronization finish. Restore all files listed in a COMPLETE backup to their original paths, including preferences and WGS metadata; do not copy RESTORE.txt into the save folder. This returns all included saves and preferences to the backup point. If you have saved again since patching, first move the current save data to a separate recovery folder so newer files are not mixed with the backup. Keep that copy until recovery is confirmed. Cloud persistence remains unconfirmed.

• Restores the 15 item flags listed above (14 cosmetics and one charm), including flags missing from the save.
• Removes matching applied-entitlement entries for PC preorder, PS5 preorder, NVIDIA, beta testers, both mailing promotions, all three Twitch drops, the China promotion, and Razer.
• Restores the two observed fallback outfit selections only when preorder flags were lost and those specific fallback values are present. Adding promotional flags alone does not change your equipped outfit.
• Recalculates the affected CRC32 checksums.
• For WGS, updates the selected container byte total in containers.index only if the changed blobs have a different combined size. It preserves the GUID mapping and sync fields.

Other outfit choices, preferences, other save sets, and the game executable are preserved. WGS backups include metadata, and the index is updated only as described above. A save whose supported flags are enabled and whose matching applied markers are absent requires no further changes.

Entitlement entries to remove counts applied-grant markers, not new items to unlock. Removing a marker is intended to avoid the analyzed revocation path when the game does not recognize its entitlement. Version 1.4.1 removes matching markers without checking live account ownership.

If the game recognizes a grant, it may add its marker again on the next load/save. Running the patcher can then remove that marker again and create another backup even though all supported cosmetics are already enabled. The owner observed seven markers returning in this way; the supplied before/after files showed only a header edit and no cosmetic changes. There is no demonstrated benefit from repeatedly removing those seven markers while those grants remain recognized. You do not need to rerun the patcher after every session if the desired items are still available.

Windows:

.\CosmeticSavePatcher.exe --check

Linux (after making the download executable):

./CosmeticSavePatcher-linux-x64 --check

Use --no-pause for terminal automation or --help for a short summary.

Supports the analyzed save layout: RMDB 2/2, header version 16, global version 23, world facts version 4, and the known nine-slot outfit container. The program stops on invalid checksums, unsupported layouts, incomplete newest sets, ambiguous newest dates, or unrecognized files ending in -header or -header.chunk. Some early checkpoints may lack the required nine-slot outfit container; those are rejected if selected.

Windows v1.4.1 was tested by the repository owner and confirmed working on October 1, 2026, following the Deathadder Jacket addition for game file version 0.564.208.5. This is a user-reported result; no independent post-test save inspection was performed. Earlier Windows v1.2.0 testing covered the expanded promotional rewards on game version 0.563.737.9. Future game updates may change the format or ownership behavior.

The Linux x64 build uses the same patching logic. A Linux user reported that v1.2.0 ran successfully in issue #2. The report does not specify a distribution or confirm Steam Deck compatibility or in-game results.

The WGS storage reader accepts index version 14 and container metadata version 4. Unavailable referenced containers, ambiguous mappings, linked directories, and changing metadata cause it to stop. Shared source builds on Windows and Linux; the Xbox app WGS workflow is intended for Windows and is not a claim of Xbox cloud support on Linux.

Item names, flag IDs, and the corresponding reward sources were read from the installed game's databases. The full supported item list is shown above.

No game files, personal saves, or account credentials are distributed here.

On Windows with the .NET Framework C# compiler installed:

powershell -ExecutionPolicy Bypass -File .\build.ps1

This produces CosmeticSavePatcher.exe beside Program.cs. No external packages are used.

For Linux x64, install the .NET 8 SDK or later and run from the source folder (cross-building on Windows is supported):

dotnet publish CosmeticSavePatcher.Linux.csproj -c Release -o publish/linux-x64

The output is publish/linux-x64/CosmeticSavePatcher-linux-x64. The build downloads the official .NET runtime packages; the resulting executable works without a separate .NET installation. The project pins runtime 8.0.31. There are no third-party application dependencies.

.NET runtime license and third-party notices are also embedded in the Linux executable.

Use source files from the version you want to build. The original v1.1.0 tag predates Linux support; its automatic source archive does not contain the Linux project.

Start with AGENTS.md. Technical references cover the save format and supported flags, findings and evidence, and build and release workflow.

Xbox WGS file support was contributed by hdfyeg35, with metadata and path-safety fixes added during integration.
