EDIT version 1.2:
If you downloaded 1.1 version before, please, download again this new version, LBN_Kart_Speedway_1_2.rar. SKY/MAS issues fixed. I'm really sorry for this.
EDIT version 1.1:
If you downloaded before 1.0 version, please, download again this new version, LBN_Kart_Speedway_FIXED.rar. I inserted a TDF file in this version. Without this file track don't load and game crash to desktop. Sorry for this inconvenience.
