Thanks Wyrmkeep for sending the box by international shipping.
I just received the ITE box and noticed that in the instructions it means to run ITE under Wine or other Windows emulator, but it also runs fine under Linux ScummVM, maybe even faster and better than under Wine.
All you need is to run ScummVM, add the Game executable into the menu. Then you can run the game from ScummVM menu. It also works with other DOS type game as Monkey island 1,2 Indiana jobnes, maniac mansion etc.
Savegame, sound effects and music works well.
The game runs natively under Linux -- no emulator is required.
