Nightdive says Dark Forces has been 'difficult to change' because LucasArts created its own version of multi-threading years before it became popular

Star Wars: Dark Forces is the latest nineties' PC gaming classic to receive an overhaul from remastering maestros Nightdive Studios. But as this month's PC Gamer magazine reveals, LucasArts' shooter has proved unusually challenging from a technical perspective. Speaking to PCG's print editor Robert Jones, Nightdive's project lead on Dark Forces explains the game features a homebrew equivalent to modern multi-threading that was years ahead of its time.

"Dark Forces has been difficult to change, from the technical end of things, because it is very heavily over-designed," says Max Waine. "There were a lot of small details in how LucasArts did things at the time that made stuff particularly difficult." One of these things was the aforementioned multi-threading solution. "They managed to do multi-threading effectively, using a task system in the mid-1990s. We had to use sophisticated modern techniques to be able to get it to work nicely, while keeping the same basic idea."

Nightdive was able to make this work, Waine says, because "unlike other projects, we managed to get the source code from the start." Yet even with immediate access to the source code, it wasn't easy. "We had to modernise all these concepts that worked for programming in DOS for your 486 or Pentium, but do not fly on your 16-core, infinite gigahertz modern processor."

While reckoning with Dark Forces' bespoke multithreading approach was the biggest challenge Nightdive faced on Dark Forces, Waine says it wasn't the only one. "The other thing that's been difficult to appropriately modernise is the user interface that they had, in terms of menus and such, because the menus are all mouse driven in the original," he says. "Finding an appropriate balance that feels faithful to how the original menus are, while being able to work while you're on a controller, was quite difficult."

Rick has been fascinated by PC gaming since he was seven years old, when he used to sneak into his dad's home office for covert sessions of Doom. He grew up on a diet of similarly unsuitable games, with favourites including Quake, Thief, Half-Life and Deus Ex. Between 2013 and 2022, Rick was games editor of Custom PC magazine and associated website bit-tech.net. But he's always kept one foot in freelance games journalism, writing for publications like Edge, Eurogamer, the Guardian and, naturally, PC Gamer. While he'll play anything that can be controlled with a keyboard and mouse, he has a particular passion for first-person shooters and immersive sims.
