I think I figured it out (not sure if it's the correct way, I'm still new at this)
I just did a hexdump -d AppleCamera.sys
on your file and used the offsets you provided to in the wiki the locate the dat files.
just the first and last lines are shown for each file
1871_01XX.dat
28952 01793 02560 00021 00000 00000 00000 00000
02599 00000 00000 00000 03500 00000 04500 00000
1874_01XX.dat
29720 01793 02560 00021 00000 00000 00000 00000
02599 00000 00000 00000 03500 00000 04500 00000
1771_01XX.dat
28951 02049 02560 00021 00000 00000 00000 00000
00000 00000 00000 00000 00000 00000 00000 00000
I was able to easily identify these three dat files in my AppleCamera.sys
file
I also located an additional three files immediately following 1771_01XX.dat
unknown.dat
29718 01281 02560 00021 00000 00000 00000 00000
00000 00000 03500 00000 04500 00000 00000 00000
unknown.dat
29974 01793 02560 00021 00000 00000 00000 00000
00000 00000 03500 00000 04500 00000 00000 00000
unknown.dat
28950 01793 02560 00021 00000 00000 00000 00000
00000 00000 03500 00000 04500 00000 00000 00000
Each of these files is the exact same length of 18048 bytes
I believe they correspond to these three dat files:
/usr/local/share/firmware/isp/1671_01XX.dat
/usr/local/share/firmware/isp/1674_01XX.dat
/usr/local/share/firmware/isp/1675_01XX.dat
I'm not sure how to sort out which file is which.
If were to install windows + bootcamp drivers on my macbook, would these dat files manifest themselves on the filesystem somewhere?

Hi, I found the offsets by looking at the disassembly of the driver. The code that loads them into the ISP tells the offset and size of the sensor files. Unfortunately the 167x versions are not available in the bootcamp driver from 2015 that we can download directly from Apple.
