Well it depend on how long ago that was. The old version of AGHT was not compatible with fate/hollow, but the new one released recently (8/24/08 i believe) has a coding that works with fate/hollow so try using KiriKiri. There are a significant number of peoples playing the game this way so it's probably coherent to some extent.

edit: I'm downloading the game right now so i'll test it first and post the result along with the working config later.
