I'm having trouble understanding Hex editing

[J9001]

Hi,

 

So i've been following  and i'm confused about a couple of things:

 

1) When i search for a hex value, some of my converted decimal values are an uneven number, which i've found can't be found since the hex values are in blocks of 2. Does this mean i can't switch out these audio files?

 

2) When i've found the file i need, i'm not sure how to find the offset and size of file. The given example is hard for me to understand. http://i1125.photobucket.com/albums/l587/jsamuels1978/HowtomodifyAudioinWWE2K14-003_zps4b9eb307.jpg

I was also finding issue with the values being uneven. In the example, it works out that you can put the values in perfectly because the 0s can be discounted. But the one I tried to edit had 7 different numbers/letters and would have therefore taken 7 slots. Anyone help out, here?

Give an example of the decimal number you are trying to convert to hex

Bit stuck on this as well with steps 21 and 23, not sure where it has the size and length of the wav file in the Hex editor.

Sorry for the late response: 25392730 to hex is 183765A, which i cant find because it's uneven/not in blocks of 2

So in hex that would be 01 83 76 5A

Open the file in Hex, go to the bottom and find the address right at the end. That is the size of the file in Hex.

Thanks for that, its making more sense in a different hex editor than the one I used before.

 

 

Just wondering where does the circled digits come from? I'm guessing the last red ones that I didn't circle are the offset I divided by 8 earlier on?

Thanks for the reply. However, when I search for that hex value it doesn't appear. The only value i can find containing "83 76 5A" is "FE 83 76 5A", which mustn't be right, as it's not 01 at the start.

 

Even if that was it, i still don't understand how afterwards i can see the offset of the file or the size of the file.. 

 

It seems to be that most the time i can only find files by removing the first 2 hex digits.
