You have important university notes and will be screwed if you can't get at them? Why then, did you try installing a game on a system that you know is messed up before making sure everything was fixed?
After dragging the OS 9 System Folder to your drive, did you try to select that system in the Startup Preference and restart in 9?
If I were you at this point, I would boot off the OS X CD and reinstall the system using the Archive option. This way you'll have a new working system and your files will be safe. Then backup anything important to anther machine, etc, whatever you have available, then initialize the drive, install the 9 drivers, and reinstall X clean and then install 9.
