There are some games we're able to package using DosBox or ScummVM - it takes about a week to wrap them up and test on our machines and port to OSX and Linux when possible. If we go through a remastering process like we've done with Strife: Veterans Edition or Noctropolis it can take 6 months or more.
Turok is pretty much rewritten from scratch! We use a proprietary in-house engine that houses the content ripped from the original game. To get the results we were looking for this was our only option. Fortunately, one of the original creators wrote us an email and attached the source code! This sped things up considerably.
We were provided the source code to Noctropolis by the original designer who also helped us translate the assembly language code into, I believe was C++? He had all the original source files which is rare to come by,

When is it not?
You guys really are doing wonderful things for the gaming industry. This might sound like hyperbole but mastering engineers are regularly tasked with going back to old albums and sprucing them up for new "remastered" releases. You're essentially doing the same for games and this is a Good Thing.
