Well, sorry to burst your bubble mate, but lack of savegame compatibility between different versions and editions of games is hardly something new or unusual in gaming. Weather it's a good thing or not is entirely a subject for another discussion. As for trainers and savegame editors these kind of programs are always written by fans and take some time to appear after a game or even a new version of a game is out. You can't seriously expect a trainer made for plain Ego Draconis to work on Dragonknight Saga.
