TIL WololoKingdoms can be run in a WinXP machine with the proper specs.

While you can't run the installation program (let alone the converter) in WinXP, you can actually play the mod, as long as you've:

a. Installed the HD version via Steam, from a partition with a modern OS (Win7, Win8.1 or Win10) and with at least one, two or all of the expansions. b. Copied the installation files of both the base AoC and WK into your own; just make sure you create a backup.

Also, funny bug, but if you play the Barbarossa campaign with the mod, there'll be Gaia Elite Shotel Warriors.
