I just ran FC /B (DOS binary file compare) on the uncracked Wiz8 .EXE files from the official 12_12 (1.2.2) and 12_23 (1.2.4) patches, and they are QUITE different (despite having the same file-sizes).
Shame on GCW for assuming that they are the same just because the sizes are the same and because the game still runs when you copy the 1.2.2 EXE over the top of the 1.2.4 one!
Now we have to wait for GCW to correct the faulty claim and then wait for someone to make a proper NOCD for 1.2.4
