there is not a known way to bring the urban court back by selecting it for 1v1 games. however it has been known possible to play 5v5 games on these courts.
you should see this

now remembering that any court made in 06 or 07 will work in 08 you can hit up our download section and see what we have there. for instance
there is tandy for 06

then the urban court from 06

and finally both together

now lets say you want to play these 5v5
well all you need to know is this tutorial

download what you want, then use the abbreviation list, and rename the first four letters to the court you want to replace. for instance "as90" would replace the all star 90s court.
now, as for the files you found, tandy is exactly the same as 06 I believe, I dont have 08 installed right now so I am not 100% on that. however that urban court you found [u]will not work[/i] in PC live 08. reason being because it is a mixture of xbox and ps2 files.
So again, I don't really know exactly what your main goal is in all of this, so if you want to try explaining it again, I'm sure its been done and that I could be able to help.
