There are multiple mods for the same purpose, I've tried this one - Diablo 2 Inventory - and it works fine with PlugY.
- Backup your stuff - either copy the entire game and save folders to another location (just to be extra safe), or backup
data folder in the game's root - Inventory Mod only adds files into this folder.
- Download Inventory mod and unpack it into the game's root folder. It should add
data folder if you don't have it yet or add some files inside it if you already have some other mods there.
- Create a shortcut for PlugY.exe. In the shortcut's properties add
-direct -txt to the target field, it should look like this:
D:\Games\Diablo_2\PlugY.exe -direct -txt . This option forces game to read modified files from data folder.
- Now you can launch the game with this new shortcut and both PlugY and Inventory mods should work together.
Here are my screenshots to proof this works:
With PlugY but without Inventory Mod:
With both mods enabled:
