The emulation patent that Sony registered is a HARDWARE based emulator patent, let's say something like a peripheral that you could buy saperatelly.
Everyone that can read the schematic can understand that it's not just an enclosed code patent inside software but there is a hardware inbetween the whole story.
Whoever is that Spencer guy (I guess he is not from Resident Evil series huh? XD) did a very nice explanation what does an Interpreter and a Decompiler do in emulation but missed the fact what the schematic shows exactly. He kind of explained exactly the opposite what this patent shows in this schematic.
...and the worlds shall reconnect
