Update:
I managed to get the demo, and I copied the backgrounds (in the SKY folder) and pasted them into the RCT3Platinum folder to get the backgrounds back (I made sure to create a backup folder in case I wanted to rollback). the only problems is now the City Background can be selected but it doesn't show up, and some lakes/ponds will appear black now.
EDIT: PROOF!
Now to figure out how to get the old peeps sounds back in the game. if anyone want's to help, I'm all ears.
