Editting Firmware

[Creedyou]

I bought an Archos MP3 player and it allows for firware upgrades via a .sos file from Archos. I was wondering if anyone knew this file format and if it is possible to disassemble to add some features.

It would be very difficult to do yourself without documentation on the firmware itself and the device that runs the code. Additionally, I don't think you would be able to add much to what it already does. Firmware updates are mainly used to address minor issues found with the product.
