That's rather annoying, have you contacted support about it?

Before we go into that, why don't we ask which?

I knew there's a reason why I kept backup copies of both the older CD and DVD editions of Riven (GOG-versions). I was THIS close to remove them from my hard drive when Riven became ScummVM-based, but I decided to keep them for now.

Now I know why it made sense. Sometimes being a bit of a hoarder and OCD or some other acronym helps.

It's a long-shot, but is the original EXE still in the folder?

ScummVM devs won't add the required support to Riven to enable access to the in-game console, claiming that the effort needed is too much for something they consider unimportant and that not many would use.

It's a right shame, because the easter egg is one of the ultimate ones, a loving slideshow of the people that worked on that game, that managed to remain hidden in the game code for years without discovery.

There's also other things you can do with the console like view all hotspots, teleport to certain areas, toggle events on and off... it's basically a debugger's dream.
