The source code for Silent Hill 2 and Silent Hill 3 was lost prior to their HD makeovers, according to Konami.

The incomplete nature of the code Konami had to work with goes some way to explaining some of the more baffling changes made for the HD remakes.

“We got all the source code that Konami had on file – which it turns out wasn’t the final release version of the games,” said senior associate producer Tomm Hulett.

“A lot of assets such as textures and sound had to be taken out of the compiled game, and that brings with it a host of unique issues, especially taken on top of the tricky coding workarounds at play in the original games. We certainly had our hands full.”

This meant the team not only grappled with bringing the games onto a new console, but also with getting them running smoothly.

“So during debug we didn’t just have to deal with the expected ‘porting’ bugs, but also had to squash some bugs that the original team obviously removed prior to release, but we’d never seen before.”

“I think at one point Heather was blue.”
