Though it's probably unexpected news, the director of programming for Xbox Live, Larry Hryb, has confirmed via his personal blog that the Xbox Originals program will
not allow for its releases to feature any Xbox 360 enhancements, ie achievements and gamer scores.
Hryb has stated that while it "would have been cool" to implement achievements, it's "just not possible" for "a variety of reasons."
Here's the excerpted material from Hryb's blog:
I have gotten quite a few questions about yesterday’s Xbox Originals announcement. Specifically, folks want to know if these games will have additional functionality like Achievements and Gamer score. The answer is no. “These are the original games that were created before Xbox 360. In order to preserve the integrity of the original gaming experience they provide, they will have the features available at the time of their initial release.” I hope that clears that up.
