Seems SCUMMVM is starting to add the Mac version of Pegasus Prime to the system, its currently going through open testing :D Sounds great and could possibly lead to a release under scummvm? (Is that allowed? Not sure..)

This is fairly old News. Presto Studios is trying get a Mac and PC release via ScummVM. It will be a kind of a Director's Cut of Pegasus Prime that includes features from both old mac version and the unreleased PSX version. They intended to sell it on GOG in the future.

There is currently a new windows demo out too.

Unfortunately, it seems like the project has stalled. The entire team has been MIA since June.

I just noticed the lack of updates from Presto. Does anyone know what is going on? I was really looking forward to this. I have been putting of playing 2 & 3 so that i can start with the first one.

Yeah, you and me both.
