What It Does
┌────────────────┬─────────┬──────────────────┐
│ Setting │ Vanilla │ Modded (Default) │
├────────────────┼─────────┼──────────────────┤
│ Starting slots │ 50 │ 200 │
├────────────────┼─────────┼──────────────────┤
│ Maximum slots │ 230 │ 500 │
└────────────────┴─────────┴──────────────────┘

Your existing bag upgrades still count. If you’ve collected 20 slots worth of bags, your total will be 220 (200 + 20) instead of 70 (50 + 20). You can also set custom values — want 999 slots? Go for it.

Installation
1. Download and extract the zip
2. Double-click CDInventoryExpander.bat
3. The script auto-detects your game install
4. Choose option 1 (preset 200/500) or option 2 (custom values)
5. Launch the game — your inventory is expanded

No Python, no .NET, no extra software needed. The script uses only built-in Windows tools. Want to verify it’s safe? Right-click the .bat file → Edit — it’s plain text, you can read every line.

Uninstall
Three ways to restore vanilla:
– Run the script again and choose option 3 (Restore vanilla)
– Steam → Right-click Crimson Desert → Properties → Installed Files → Verify integrity of game files
– Manual → Go to your game’s 0008 folder, delete 0.paz, rename 0.paz.backup to 0.paz

How It Works
The game stores inventory configuration in 0008/0.paz as part of the InventoryInfo data table. The Character inventory type has two uint16 values: _defaultSlotCount (starting slots) and _maxSlotCount (hard cap). This mod patches those two values directly in the PAZ archive. The game reads the patched values on startup — no runtime injection needed.

Compatibility
– Works with Steam, Epic, and GamePass versions (as long as the PAZ file layout is the same)
– Compatible with other mods (controller remapper, ReShade, Special K, etc.)
– Safe to install mid-playthrough — your save file is not modified
– Game updates may revert the patch — just run the script again after updating

FAQ
Q: Will this get me banned?
A: Crimson Desert is a single-player game with no anti-cheat. This mod only changes a local data file.

Q: Does this affect the UI?
A: The inventory grid expands to show all available slots. No UI issues observed.

Q: Can I set slots higher than 500?
A: Yes, use option 2 for custom values. The maximum possible value is 65535. Values above ~1000 are untested and may cause UI issues.

Q: I updated the game and my inventory is back to normal.
A: Steam overwrote the patched file. Run the script again.
