Welcome to the Oddworld Forums, ignorant bliss.
The problem you are describing is a well known issue. Unfortunately it's due to the shoddy backwards compatibility that Microsoft Games (
MG) has implemented with Munch's Oddysee. At the moment there is no solution, nor does it appear that
MG has any intention of rectifying it.
Sadly, it's down to bureaucracy -
MG does not believe Munch's Oddysee is worth the extra time, and furthermore, it appears they won't even provide backwards compatibility for the superior Stranger's Wrath.
I sincerely apologise, you're missing out on the full experience of a fantastic game.
