Oh, my bad
We only need to make sure the Sultanate of Sulu didn't sell it to the White Rajahs for a pre-1900 POD
But Sabah won't be a part of Malaysia though
I also have another POD in mind but it's post-1900, Malaysia won't even have Borneo
Oh well, I'll stick with this one
Hmm can't think of one where it's a part of Malaysia though
