I can't remember offhand any schedule updates being posted in the NBA Live 06 section but updates for NBA Live 07/08 should still work. You might want to run a
Search for them. As for art updates, I'm not sure what you mean by "despite the NBA Live PC Project" but again you can find releases for 06 here in the NBA Live 06 section, to look for something specific I'd once again recommend the Search function.
