I screwed up on mission 10 (the one where you have to free the prisoner and steal the horses at night, without alerting the campfire) because the instructions weren't clear- I saved too far in and don't want to replay the mission. I saw there were cheat codes for this game... if you press Shift + F11 you can put in codes, but it doesn't work for me. Any ideas why?

My guess would be the cheats don't work in the reworked version. They were meant for the 2001 original .exe and while the recent revamp improved compatibility, it broke those.

I just returned here to see if they had replaced the developer console, as they claimed at the time they were going to do with a patch.
But it seems they lost interest and it's still lacking.

To the GOG Team: Are there any plans to make the console available again? That would be very helpful. Thank you
