XStoreUnlocker

DLC unlocker for Microsoft Store and Xbox PC games. Works on games that use the XStore API for validating DLC ownership.

Install

You need three files in your game folder:

File	What it is
XGameRuntime.dll	Our proxy DLL (from the release zip)
XGameRuntime_o.dll	The real Xbox runtime (you provide this)
xstore_unlocker.ini	Config file (from the release zip, or auto-created on first launch)

Steps:

1. Copy XGameRuntime.dll from C:\Windows\System32 into your game folder
2. Rename it to XGameRuntime_o.dll
3. Drop our XGameRuntime.dll and xstore_unlocker.ini from the release zip into the same folder
4. Launch the game

Your game folder should look like this:

GameFolder/
  game.exe
  XGameRuntime.dll          <- ours (proxy)
  XGameRuntime_o.dll        <- the original from System32
  xstore_unlocker.ini       <- config

Check xstore_unlocker.log in the game folder to confirm hooks are working.

Configuration

The INI file is created automatically on first launch if missing.

[Settings]

Key	Default	Description
unlock_all	1	Patches every DLC the game queries from the store as owned. Covers most DLCs. Does not cover unlisted DLCs the game never queries for. Set to 0 to disable.
log_enabled	1	Writes to xstore_unlocker.log and OutputDebugString. Set to 0 for silent operation. Errors always log regardless.

[Blacklist]

Store IDs to skip even when unlock_all=1. One per line.

[Blacklist]

[DLCs]

Some games have DLCs that exist in the store but are never queried at runtime. Promo items, hardware bundle exclusives, delisted content. The unlock_all option cannot reach these because the game never asks for them.

Add their Store IDs here. The unlocker injects fake owned products into the game's query results so it sees them as purchased.

Get Store IDs from dbox.tools by searching for your game.
