Quoted from Coyote:We're talking WMS and TZ here. Not sure why you decided to bring in DE. The two folks that were releasing patches for WMS games (whom TZ is made by) took their patches offline, because of something going on with PPS. So it wouldn't matter what anyone doign with another manufacturer's code does, as if someone here were to release a patch for TZ, they, too, would likely be asked to take it down and have a talk with PPS/Rick.
They can be asked, but producing patches (and not full rom distributions) has been considered legally acceptable.
