Okay... Instead of cross why not just siege -> extraction? There is no way to read the inventory of a player at all? It's all just data, I can't imagine anyone with the know how would have trouble copying some data via SQL. If the data is incompatible that's because the game was created without compatibility in mind which isn't just an assumption, it would've had to have been a very deliberate decision seeing as animations, sounds, etc... All seem to have been taken straight from Siege.
