I've demoted other SCI game versions to unsupported once we've discovered that they in fact weren't done, so yes this appropriate.

Let's keep the "Demo" string and just add a comment to the detection entry that it uses Version 4 of Robot videos, which we just haven't implemented yet in RobotDecoder. The "Missing game code" is for the severe case of Shivers2 where the entire game is implemented in c++ instead of scripts. This isn't that kind of fatal situation, someone just needs to care about pqswat and they can knock this out in an afternoon. (One Two Three, Not It!)

@sluicebox OK, thank you. As for keeping the "Demo" string, the problem is that, AFAICS, AdvancedMetaEngineDetection has that design limitation where you need to replace the extra flag with an explanation about why the game is unsupported; otherwise, if a user tries starting the game, the explanation printed by the UI will just be "Demo".

So I've tried to find a compromise, but maybe something more elegant can be done around AdvancedMetaEngineDetection, I don't know.

Is there any existing code or documentation that can be referred to regarding Robot v4?

@ccawley2011 We have resources. This is just a TODO that didn't happen before the previous developer left. Anyone who wants to implement this, ping me on discord. =)

@dwatteau Thanks for the explanation; I wouldn't have guessed the GUI did that. Good compromise!
