To register a track head to this address: http://www.piboso.com/trackreg/trackreg.php
Select "MX Bikes" on top.
Track ID: the name of the directory of the track.
Track Layout: the name of the directory of the layout. Empty for base track.
Track Name: the name as it will appear in statistics.
Track Code: is generated during collisions ( TRP file ) export.
Race data ( RDF file ) used for the first online lap is registered.
To update an already registered track, set Track ID and provide the previous code in Prev. Track Code. All records are deleted and race data is cleared.
Noticed any races run on TNMX get recorded as Winchester on the stats page. Do recall watching a Gdub stream where TFC commented he would like to update the track at some point (I think it's perfect myself).
Not sure why it's not working for all my sx tracks :'(
