This is an old project from 2006, carried out by Frank. The original idea is to take pak64’s scale but using 96 pixel tiles. This gives the player more space for the surrounding environment of the objects.
You can download an early demo with non free objects for a better gaming experience, but you will also need simuttd pakset and a test game. Remember the pakset is still under development.
