flypig: Yeah searching I seem to have loads of pages that say that the US courts keep building on rulings that copying into RAM is an infringement and saying that thet's wrong in great detail! I can't find any test cases in the UK/EU though. If your program is running from ROM you still have to copy it into the processor one instruction at a time where it is stored for a fraction of a second. Any ROMPatching would copy pages into ram etc. Hopefully the EU courts will rubbish this argument if it ever comes up though. If they remember what copyright law is for it's designed *not* to stop people using it freely, it's only designed to stop them spreading it around and thus devaluing the copyright holders right to copy and distrubute.
