The Japanese version of Abe's Oddysee is called Abe-a-go-go. The Japanese version of Abe's Exoddus is called Abe 99.
Go
here for a couple of screenshots (all I could find).
I once saw Abe 99 on eBay... there were two copies, but one guy won both of the auctions, so still I search too for the elusive Japanese copy of Oddworld. Not that I can understand Japanese, but it would be cool to have a differently named version of Oddworld.
I wonder if Munch is going to be released in Japan... and if so, if the name will be changed.
Abe Babe...
