ZDoom

THe 'unknown game type' message is a relic from the old DECORATE. It doesn't have a mandatory keyword to start an actor definition so everything is allowed. That means that the error is caught too late for a more appropriate message. When the parser fails it fails in a gamemode check.

The other one is a bug and should be reported as such.

I've noticed that you get totally irrelivant error messages when using decorate. For example, you get a "Unknown game type" error if it doesn't know what the actor is. Also, zdoom just gives a crash log if you miss out sprites that are in the decorate lump. Isn't it possible to give a little bit more help to what the problems are rather than giving a message that's totally confusing and irrelivant?
