Alcon, as it turns out, was happy to help. It had the legal rights for Blade Runner, and entered a publishing agreement with GOG. Though it took a few more years to get everything in order-when asked how GOG and Alcon navigated the licensing issues, Hill says, 'If you knew I would have to retire you'-everything slid into place and GOG turned to the people working on ScummVM, a program for running classic point-and-click adventure games on modern computers, to get Blade Runner running."
"Luckily, one community member had already started the recreation process eight years ago. 'He started by tinkering with the code and digging up unused or cut out content, like dialogue lines or entire story branches,' Hill says. The final team was a group of four people who collaborated to make the game playable on modern operating systems, but even then, you would need the original discs.
Once the legal obstacles cleared, the ScummVM team helped get a version put together that could go live on GOG. ScummVM had already worked for past games like the Monkey Island series, Broken Sword, and Myst. Blade Runner was fully in the ScummVM team's wheelhouse. Though the current build is based on the original box edition with applied fixes-the source code is, as far as anyone can tell, still lost-ScummVM allowed the team to apply fixes and get the game working on Windows 7, 8, and 10, as well as Linux and Mac OS X."
Thanks for copying the whole text, so you can now compare it to the current version after sev contacted them with corrections. The ScummVM developers were contacted by GOG.com after version 2.1.0 was already released and only helped with the packaging, there was no collaboration with getting Blade Runner.. running.
Yesterday they also got 10 game codes from GOG.com, a little redundant but eh? There was no compensation from Alcon AFAIK but that's the same for all publishers that have been re-releasing their games with ScummVM, sadly.
