First of all, don't start a new thread about the same issue.
You've got to understand that everything about the starter pack is in german, the tutorial, the documentation of the additional functions, its community, everything.
THERE IS NO TRANSLATION YET.
If you still want to use the pack's graphics, download the resources seperately from this page:
http://maniacmansion.microspace.ch/resourcen.htm
The bottom three linked zips contain the characters, additional backgrounds and Maniac Mansion Deluxe's backgrounds.
Understand, that to test your pack game in english requires you to use an english translation file at all times, since the main GUI will be german otherwise. (English buttons are implemented in the pack but activated by the translation file.)
I'm not sure how expericened your are in working with AGS, if you are merely a beginner, I'd suggest doing something else first. The pack isn't exactly aimed at beginners.
And, most importantly, as of now, MMM is a german project and we intend to keep it that way. There will be occasional translations of episodes, but that's it. You might want to take a look at the
Reality-on-the-Norm project, the english counterpart of MMM.
