The team behind the remaster, Hijinx, were supplied with buggy and unfinished code by Konami in order to create the updated versions. Konami didn't store the original finished development code in a usable format, and as such the team were tasked with fixing the bugs from the code along with porting the titles to new formats. This took the team 2 years to complete - the same volume of time it took for Silent Hill 2 to be developed in the first place.
