I'm supposed to find the flag somewhere but this g...

I tried treating the two PNGs as a forensic/steganography challenge rather than an EE problem:

• Checked PNG metadata/chunks → no EXIF/text chunks, no appended data after IEND.
• Checked common LSB steganography approaches:
  • RGB channels
  • individual bit planes
  • channel permutations
  • reversed pixel orders
  • combining the two images
• Nothing produced a readable bronco{...} string.
• The images themselves appear to be normal PNG renders of:
  1. a paper table about Radix-4 Booth multiplier designs
  2. a Booth encoder transistor schematic

The EE content is likely a clue, not the payload. The key words are:

text
RADIX-4 BOOTH
BOOTH ENCODER
PARTIAL PRODUCT ROW

However, from the two images alone I cannot recover a valid flag. There is no visible bronco{...} string and no straightforward stego payload in the PNG data.

The challenge is probably expecting one of these additional steps:

1. Use the original image files, not screenshots
   (Screenshots often destroy LSB/stego data.)

2. Run a stronger PNG stego tool such as:

   text
   zsteg Challenge.png
   zsteg ChallengeCircuit.png

   because it checks unusual bit ordering and pixel traversal patterns I cannot fully reproduce manually.

3. The EE clue may indicate a Booth encoding extraction, where the circuit/table provides bits that must be decoded.

If you can upload the original challenge ZIP/files (or the exact two PNGs from the CTF download), I can continue and extract the actual:

bronco{........}

flag. Right now the supplied images do not contain an recoverable flag through standard forensic extraction.
