I still cannot believe it but I did it... After a good idea, 6 hours of work and a lot a lot of digging I've unlocked the ROM image in the emulator CTP. I will describe tomorrow the method but right now I will just post some screenshots, upload the bin somewhere so I can give you the link and go to sleep cause it's almost 2 o'clock in the morning.
I will also test it better tomorrow put I saw that it has a file explorer :) and a VERY nice task manager:
I have decided to take down the link because Microsoft could get upset and I don't really want that (if someone at Microsoft will tell me that it doesn't bother them I will put it back).
Anyway I will explain later how I was able to do it (cause it was done for educational purposes only) and I think this won't cause me problems. Right? :)
