Asgard Software, a company responsible for many adventure games on the TI-99/4A computer, released a number of Infocom games that were not ported to the TI by Infocom. Details are a bit sketchy but possilby these six titles were released: Hollywood Hijinx, Leather Goddesses of Phobos, Lurking Horror, Plundered Hearts, Stationfall and Suspect. Here is solid evidence that they do exist.
The manual with this game is essentially identical to the one from the Solid Gold release. It is hard to say whether these were released with Infocom's blessings or not.
