Hi,I just downloaded from your site Lemmings for the Atari ST. To be more precise, this file: "Lemmings (1990)(Psygnosis)[!]". However, when I extract the zip file, it appears as an STX file. And my emulator, STeem SSE 3.9.1 doesn't detect it. I searched online for how to deal with it, and every page tells me that it is a project file created by an application called Pinnacle Studio. Why it is in that file extension? How can I deal with it to make it run?
