Yup, I'm starting to think the US version doesn't have a console, because I can't find a solution anywhere. I don't get a garbled console...I get NO console, at all. Even after following the instructions for editing the file (true instead of false) and adding the files to the Data folder etc. I can get Marvin mode to work, but that's only for the function buttons and it's not very useful. It's a bummer because I love to play the game the second time around in god mode, just for fun.
I have the US version of the game and by following the info in the cheat faq have been able to get the console to work. The cheats are CASE sensitive, for example to get more gold i type: give It_Gold 50000 and get 50k of gold. a couple of things worth noting is that on the US keyboard ingame when you are typing, z is y and y is z also to get the underscore It_ Gold you have to hold SHIFT ?/ key. another thing that works for me is the learning points cheat i get that by typing: teach LP 500 again these cheats are case sensitve. also you must create the folder the cheat faq says to make in the gothic program in order to have any chance of making the console work
