System: Windows XP
Game: Maniac Mansion C64 (German language)
playing with Dave, Syd & Bernard
Bug description: If Dave it trying to do anything with the rocket car's trunk, he always goes to a wrong position. Therefore it isn't possible to open the rocket car's trunk with the yellow key (Öffne Kofferraum mit gelbem Schlüssel). That means, it isn't possible to get the tools (Werkzeug), which are inside the trunk.

Screenshot from the c64 with Dave's correct position
you can avoid this problem by walking right behind the trunk before attempting to use the key on it.
Fixed in ScummVM SVN, by the patch provided by segra.

Works fine using ScummVM 1.3.0svn53822 (Oct 25 2010 23:36:48). Dave goes to the correct position now and therefore he is able to open the trunk.
