It should be noted that the original owner of this early copy of the game damaged the gamedata when it was improperly being dumped. Or something like that. This poster acquired the damaged game after-the-fact, and has now released, from my understanding, an unmodified-but-damaged copy of the game, and then another copy of the game where assets from the final release have been transplanted to get the early copy working.
It's hard to tell whether the damaged prototype had bugs or problems because of the damage, or because it is an early copy of the game.
