JudasIscariot: I don't know about Agarest but I know Durante's fixes are usually a couple of DLL files that need to be placed into a particular directory along with some ini files.
I used his fix for the GOG version of Deadly Premonition so if he has the same kind of "fix" for Agarest then everything should work :) No guarantees though as I have no idea what the Agarest fix actually entails :)
omega64: The following is from memory:
Supersampling and a turbo button for combat.
Which is great as the combat is SO slow.
Like I said before as long as the fix for Agarest follows Durante's usual pattern you should be good but that will all come out once the game is released here :)
