Sadly, after FF7's release, much of the original work simply vanished. There very little version control and coordination between the creatives. Also, because of the lack of versioning, the code that was given to the FF7PC port team wasn't even the final version. Work started, and then stopped as Square had to pull a newer version from the archives (backup tapes). It wasn't until square started up-porting the series to new engines did they discover the need to have some kind of asset control.
