manuel, it's the user's "my documents" replacement; so first I just made an "openMSX" folder there, got the stuff from SVN, compiled it and tried to run it -- apparently the emulator wants to create/use the same folder for saving the user settings etc. which got the TCL scripts confused as that folder already had all the bells and whistles there. When I renamed that folder and restarted the emulator there, it worked.
