I am very new to OOTP.
I've played some SIM games and I'm having a blast.
I have figured out some of the GMs job, how to work with the salaries for a team, how to trade, use my minor leagues and how to use my bullpen.

I would like answers to the following tech/download questions if possible.

How can I download and load historic ballparks?
How can I download and/or update a teams' file with logos and uniforms that coincide with real teams?

Thank you.
Franklin
