I'm not sure if you can do much with the court .ebo files in NBA Live 2005. There's a couple of tutorials about hex editing court files in our Tutorials section on the main site, but they're a bit outdated now so I'm not sure how relevant some (or all) of the info might be.
I think Andreas already answered that question in another thread. Again, please don't make brand new threads to ask the same question or a similar question to an existing topic.
As Andreas said, it's not possible as far anyone knows. It might be possible if we could do more with the .ebo files.
