It's good to see that camera manufacturers are more prompt at releasing firmwares for their digital cameras. Now that the Olympus E-1 firmware is at version 1.4, would it be useful to see what was changed between version 1.3 to 1.4 with a hex editor? Maybe it'll help with understanding the firmware and whether any features can be enabled or hacked.

How much can you tell with a hex editor? Can you actually see what has changed or do you just get clues from the strings? I have been playing around with the firmware from my mp3 player, so far I have figured out what the instruction set is, but I can't do anything else without disassembling it. I'm new to the whole thing so I don't really know what I am doing. I wrote a C++ program yesterday that finds strings in a binary file and saves them to a seperate file, if you are interested in the exe file or the code.

Which MP3 player are you playing around with? It would be interesting how you figured out the instruction set.
I'm sure you already know. With a hex editor, you can see what values are in the file and what differences are there between the two files. Sometimes, a configurable value is changed, it's easy to decipher them when you have two different versions of the firmware.
Your C++ program sounds useful, please post it. I wrote a Java BinDump program before. I'll try to dig it out or see if I have already released it somewhere . . . Should probably write a Java HexDump as well.
