If you wanna play a version with the original backdrops then you should try the original 2 disk release by Quartex.
Wall, The (1987)(Rainbow Arts)[m QTX](Disk 1 of 2).adf
Wall, The (1987)(Rainbow Arts)[m QTX](Disk 2 of 2).adf
Or the 1 disk version "cracked"(???) by Blizzard.
Wall, The (1987)(Rainbow Arts)[h Blizzard].adf
You can find these disks at PlanetEmu of course.
But there is no fully working version of the Star Frontiers release in TOSEC.
At least some files of the later levels are damaged.
And even some files of my copy from 1990 were damaged.
That's why i did compare all available dumps to rebuild the release from 04th January 1988.
But i included a new intro on this disk since the "hidden" Star Frontiers message (invisible $0A0A0A filenames) was rather boring.
btw ... if u r playing "The Wall" without Fast- or Slow-RAM then u must deactivate DF2: and DF3:
There's a bug in the Rainbow Arts intro.
And the new Intro slows down at some points on low-end Amigas, especially on A1000.
It seems the highspeed PTreplay code used by StingRay has some problems here. He did fix the original source code of Vision Factory and The Company.
Next time i will try Promizer again ... like 16 years ago ...
