Here's a few more courts. Boston & Philly are new, and Portland is an update (fixed the court line colors & cleaned up the graphics).
For the Boston court, I tried to darken the parquet floor as much as I could without making a new texture, since the wood textures are in the xcommon.viv and if you change the parquet texture, it'll be changed for all courts that use parquet, not just Boston. So I made a semi-transparent texture for the court, but it also colors the court lines, so I couldn't make it too dark.
BTW, The 76ers' file is a lot bigger because I had to change some of the texture levels in order to get the new court lines to blur more correctly. Plus, I've been using large textures for a lot of graphics since they look better.
Finally, the NewBackboard v2.1 just fixes a glitch from 2.0, and makes the end-of-quarter lights more visible (I may have already had that in v2.0 as well).
