:-) i just understood the part "not very easy".
i like rockbox on my clip and fuze. thats way i bought some fuzes for my parents, but they wont manage rockbox.
its too complicated for them. now they use the original fw again. but i had that idea to give them the option to start rockbox if they want to play games etc etc...
i am ust a comsumer and dont know nothing about programming and that stuff. would i be possible for me to "edit the arm assembly in mkamsboot, then compile your own build of the tool. " ? or maybe there is one who had the same idea and did this already?
