Big corporation: Whoops, we lost this game so we can’t re-release it. Sorry. Even if we found it, it’s not worth our time/money porting it.
Meanwhile, random person on the internet: I’ve updated this emulator so you can play old games at 4k 60fps for free. The weird bug that was never fixed at launch is now gone too.
I did this for the Witness - it really helped to think out some of the puzzles if scribbled possible solutions down. Oh and Obra Dinn to an extent - mostly things like ‘I saw this guy hanging around in this memory - could he be X’?
