Small update, some files were found by Erwin Greven but it is a massive 1,6gb packet so it'll take some time before they files are available. He needs to sort them out before uploading.
Ok, i got pretty recent source from Ebrich, it's v1.09 (if i remember right it's after beta tests) You still need to test it thoroughly, all collisions! Otherwise i think it's identical in geometry to Race07/GTR2 releases. I'll send you the download link in PM.
