Before I start, this is based on the Barcelona update created by Erwin Maliepaard, Mark Beijer, Ricardo Lampert and Laurent Rousseau. I have no intention in releasing this when completed, unless I get full permission from all authors.
I've rebuild the La Caixa corner, including the track, verges and kerbs, as well as tidy up some other small texture bugs around the area. In Erwin and co's update they put the new corner in as part of the verge... i've done the complete opposite. The new corner is the actual track, and the old turn is part of the verge. This will help later on when/if Laurent sorts the texture mapping bugs in the .gp4->.bin track surface generation feature. (any progress on this btw?) I'm now going to make a start on the .dat file.
