               Here you can download the emulator XEX file:
http://assets.xbox.c...ity/default.zip

I'd like to disassemble some instructions from this file, but I don't know which software to use. Does anyone know of some software to use ? Something that at least can translate bytes to opcodes for this type of CPU would be nice (some HIEW-like software for example).

               objdump compiled with multiarch or IDA (Interactive Disassembler).

               The update executable (default.xex) is encrypted. You won't be able to disassemble it unless you can decrypt it. Look at it with a hex editor and you will see what I mean.

Or compressed.

               The guys over at Free60 believe it to be a modified .CAB archive, much like the .XCP.

               Tried to dissasemble it with IDA, came up as binary. I looked at it with a hex editor, it's definitely encrypted. I don't know about compressed though.

And how would you decrypt it ? There's nothing known yet about the encryption technique.
