Where can one find any info as how the .trk is formed? I bet everyone of you have to edit it by hand at somepoint. And i know that there are definitive answer to this but as usual, some like to keep that info hidden. What is the structure? What information it holds? I can of course read it and it is pretty easy to understand most of it. But editing it.. whole another story. I have had to use trial and error but there is a definite limit to that approach. Maybe it could be usefull to many to know a little more about it? So, please, share your wisdom and contribute to the community. It took me a while to gather just the basic information to fix the obvious ones and don't wish to poke around blindfolded anymore. I could start this by sharing what i have learned but without the knowledge of the basic functions it would be so flawless that i probably would cause more harm than help. Of course it could be that the BTB Evo community has ceased to exist and everybody is doing either rFactor or RBR.
