I have never had a problem with Nulib (version 3.24) accepting binary files.

I also don't understand why you would have the high bit change when
transferring files unless your software is automatically translating it for
you. I use the Transfer program that came with a PC Transporter in my Apple
IIgs. It has an option for translating files but I never use that.

By the way I have no problem at all with Kegs32r3 booting DOS 3.3 (.dsk)
images. It is true that DOS 3.3 used a different sector ordering than ProDOS
but that makes no difference to the emulator.

Also if you must use a .2mg disk image it is important that the conversion from
.dsk to .2mg be done correctly.  I am unaware of any software for the PC (there
is ADFS for the MAC) that will convert a DOS ordered .dsk image to 2mg.  Are
you doing the conversion yourself?
