Parabéns, @ShoegazingLeo!
Feliz aniversário, @ShoegazingLeo! 
Lately using Dosbox-X, which doesn't use AUTOEXEC.NT at all. I don't have any lh lines either.
Happy Birthday @ShoegazingLeo!
Come to the chatroom 
Happy birthday @Leo_Ramone!!
Thank you @Duplode for answering in conform with point 2.8 Illusion tracks of GAR rules article: "(...) In such cases, either the track designer or the competition management will provide rulings on how the GAR rules are to be interpreted in the affected track sections. (...)" 
Happy birthday, @ShoegazingLeo!
@Friker, the full detailed GAR rules are available here: https://zak.stunts.hu/articles/gar-rules-at-zakstunts
@AresUII, to increase memory, try deleting the string "lh %SystemRoot%\system32\dosx" in the AUTOEXEC.NT file (save a copy of the file first).
