1.02 is the TNT patch.
By graphical errors....you mean what? If you're refering to the Odin Cut, or any Wind Effects, those are just broken. They even mention the Odin Cut problem in the readme file.
As for other glitches.... Try other video drivers. I didn't notice any in the 77.77's but..then again I wasn't really looking for any. And I only played till the first savepoint.
To busy playing my PS2, to bother with the PC, lately. Been playing SMT:Digital Devil Saga 2...as of late.
