Most computer centric board Im part of so you guys get the answer. I found a pair of Japanese version Panzer Dragoon Sagas at a market in Seoul, so I contacted James Mielke who wrote a sick retrospective on the Panzer Dragoon series years ago. I asked him why Panzer Dragoon Saga couldnt be ported. He said the source code was needed. I asked him why the game code on the CD wouldnt be enough to start a port (really why wouldnt it?) and he said that the retail version is only enough code to run the game but not port it. Can someone explain why source code is necessary for porting?
