BetterWayElectronics has released an update to their PS4 NOR Comparator tool. Version 1.7 is a bug fix release for MD5 calculation.

What is BwE PS4 NOR Comparator?

From the readme:

Don’t trust my PS4 NOR Validator? Have a whole bunch of dumps from the various consoles you have been repairing/collecting? Well now is your chance to shine! I present to you the BwE PS4 NOR Comparator! Now you can gather vital information from all of your dumps at once and compare them all by yourself!

PS4 NOR Comparator Features

1. Compare Offsets (Hex)

   You will be asked for an offset and then the length. An example of this would be ‘1CD601’ and then the length ‘8’. This will produce the ouput for ‘UNK Unknown Flag 6’ of a PS4 dump.

2. Compare Offsets (ASCII)

   You will be asked for an offset and then the length. An example of this would be ‘1CD601’ and then the length ‘8’. This will produce the ouput for ‘UNK Unknown Flag 6’ of a PS4 dump.

3. Compare Offsets MD5

   As above, this will allow for you to seek an offset and length and gather the MD5 of the area.

4. Compare Offsets Entropy

   As above, but this will gather the entropy of the area you have chosen.

5. Double Offset Comparison

   Here you can compare two different areas against each other, it will ask you for the offset and length for both.

6. Dynamic MD5 Calculation

   This is the dynamic calculation, here you have to input the location of the offset (and length) that contains the file size, then you must input the starting offset of the file. An example of this is to get the MD5 of C0010001.BIN, you would input ‘C4024’ which is the location of the size and then size length ‘3’. This is required because the file size is different in each dump and the only way to determine the size is to read it at that offset. You then you input the start of the C0010001.BIN which is at a static location of ‘C4200’. The output will then be the MD5 of each of the files in each of the dumps.

7. Compare File MD5

   This will create a basic list of the MD5 of every dump.

8. Compare File Entropy & Byte Count

   This will create a statistical output of the entropy and byte count for each dump, depending on how many you have in your folder this will take the longest time to complete.
