Hey, not sure about older "magic S" ISO version and tricks, but according to Leighm0 comments his modified ISO runs "a LUA Script on your USB stick called "script.lua" in the root directory". So without any hexedit you could try to edit that scrip...
thank you very much! I was thinking also it is inside of ifs-cmc.bin, but was not sure how to mount it on my computer? Do I have to use a QNX VM to mount the ifs-cmc.bin?
Thank you in advance.
