Hi ravnos04. Here's the good news - If you had bricked your notebook from flashing the BIOS, it would fail to boot up. You'd never get to the point of being able to launch a game. Since you CAN get to that point, your flash to 203 was successful.
I suspect there may be file or registry remnants of the previously-installed Star Wars game that are preventing re-installation. What error(s) do you receive on the re-installation attempt?
Have you tried using Windows System Restore to restore your system to an earlier time (i.e. before the BSOD)?
