Need a clear answer about BW 4.5.1


just a simple question about bw 4.5.1 :
DOES IT COPY SECURUM 4.8x (UT2003, GTA VC, VIETCONG…) CORRECTLY (no emulation needed if .bwa file included) LIKE 4.2.5 DOES?
Just read all threads twice, but nobody seems to have tried this really…
in fact, it doesn’t matter to me, with my 4.2.5 and my great LG Burner everything works great @ the moment, so i don’t need to update, but i was just wondering…
