I think self-modifying code is kinda rare case - it's made typically for
protection againt hackers , and typically on pc side. Nintendo roms probably
don't use this kind of
protection.
Anyway - I think even to self-modifying code could be some tricks like
dynamically generated code.
I would be probably intrest to re-compile only modules, like .dll - but this
would
require to analyze when and how .dll being loaded. This is kinda self-modifying
code as well ? (OS loads .DLL)

Have a nice day!
