Made the attempt to use this on a Debian sid based system which is twenty year old hardware. The processors are real Intel Pentium II ( Deschutes ) modules and there are two of them.

However :

titan# ./sifter.py --unk --dis --len --sync --tick -- -P1 -t
Traceback (most recent call last):
File "./sifter.py", line 842, in
main()
File "./sifter.py", line 817, in main
arch = re.search(r".(..)-bit.", injector_bitness).group(1)
AttributeError: 'NoneType' object has no attribute 'group'
titan#

Not sure what to do with that other than just let you know.

I am going to guess that 32-bit systems are out of the question.

Can reproduce on my Arch Linux setup, running on a Ryzen 5 2600.

Commenting out the line and replacing with arch = 64-bit worked for me, but I'd hazard a guess that any string may be fine there.

the same issue for me,
Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50GHz processor
If changing to arch = '64-bit'
get this summary:

Happened to me, you need to run make first. (make CFLAGS=-no-pie specifically)
