Fable III's was added via a title update, so you might have to manually apply the AP25 data.
As I thought:
Q: How do I know if a game has AP25?
A: ABGX 1.05 will tell you There is one game that does not show as having AP25 and that is Fable III - but it DOES have it so must be patched.
Poked all over the place and can't find the bloody site to download the ppf file to add the ap25 data to Fable III. :/
