Unwinder devised a way to remove the encryption, but still, antidetect has no effect on any of the drivers past 44.65 as far as I know.
Unwinder said if I remember correctly that as a side effect of creating "detonator decoder" that anti detect now worked again on the detonator drivers. Although that was said when the 45.23s were still official. Stealthhawks results show that it certainly has some effect on the 51.75s
EDIT: im not sure I said this earlier, but well done Stealthawk on some top quality investigation.
