I got a myabandonware copy of the game, and also on archive.org, and got it to run in both windows Sandbox mode and a VirtualBox with WinXP.

But in both places the game doesn't run well, the mainmenu is white, ingame textures are also white, and it's reaaaally slow.

Also tried compatibility modes.

Anyone knows how to fix this?

Very strange, my web archive version works on Windows 10 without any problem. Have you tried play on another computer?
