There was no Code of Bullet for HArd Boiled AFAIK. Do you want to put all CoBs together as Specials, even if they where according other Movies?
Whats with the (even if very bad quality) longer Taiwanese Version from Hard Boiled as a Special Feature? Running Time about 131 min. (It has 5 minutes of a faulty black image, so runing time of the stream is 136 min.)
I have the 5 Code of Bullets I mentioned.
