Wrong raw bytecodes?

[dk1spb]

I have a2old.flux file from old version FluxEngine (http://oldpc.su/0/01.rar) And I have tried to see raw bytecodes: fe-inspect.exe -s a2old.flux:t=0:s=0 -H

Raw FluxEngine bytecodes follow: 00000 : 0c 80 4b 80 60 80 36 80 5f 80 35 80 32 80 61 80 00010 : 49 80 33 80 31 80 33 80 47 80 34 80 32 80 47 80 00020 : 33 80 31 80 31 80 33 80 48 80 49 80 34 80 31 80

I have converted flux file to a2new.flux by latest upgrade-flux-file.exe And trying to see bytecodes: fluxengine inspect -s a2new.flux -H

4.17 us clock detected. Raw FluxEngine bytecodes follow: 00000 : 8c 3f 8c 3f a1 b6 3f a0 b5 b2 3f a2 3f 8a b3 b1
00010 : b3 3f 88 b4 b2 3f 88 b3 b1 b1 b3 3f 89 3f 8a b4 00020 : b1 b1 b3 3f 8a 3f 89 b3 b1 b1 b3 3f 89 3f 8c 3f

Why codes are different ????

and bitsream:

Aligned bitstream from 0.000ms follows: 000000 0.000 : X-X-XX-XXX-XXXXXXXXXXXXXX-XXXXXX-XXXXXX-XX-X-XX-XX Does it mean A D D F F F .... ???
