The builds need Skyscraper 1.0's data folder placed into the same folder as the skyscraper.exe file.

Build 162 (5/11/04) shows "Skyscraper 0.97 Beta".  It crashes due to stairs for a basement floor trying to be created when it can't

Build 163 (5/11/04) crashes when it starts, but works when run in VB.
It's essentially the original version with lots of the Triton Center code moved into a separate module.
Most of the Triton Center code is simply the original Truevision calls.

Build 164 (7/26/04) shows "Skyscraper 1.1 Alpha", and has a texture problem.  In this one, source code is moved into the "src" folder.
This also has the first mention of the sim engine, abbreviated as "SBSE" (Scalable Building Simulation Engine) in the startup.
The Triton Center was stripped and being rebuilt using sim engine calls instead of Truevision calls.
This can be considered to be the first actual version of what Skyscraper is today.
Also, keyboard and mouse input doesn't work because it wasn't moved into the sim engine yet.

Build 165 (8/19/04) works, and has the control panel disabled (164 probably does too) since most of the functionality was stripped and needed to be rewritten.
Positions are backwards, and nothing really works, because the sim engine hardly does anything yet.

Build 170 (8/29/04) - positions work now, the control panel doesn't really do anything.  Elevators now have movement code and other things, but the motion is too fast.  You can use the "Go" button to make the elevators move.

Build 175 (10/17/04) no longer has the original main menu.  Elevator movement is better, and the camera always moves along with the elevator in this one.

Build 177 (12/14/04) - elevator motion is much better.

--- The C++ version was started between 177 and 185.

Build 185 (8/31/05) starts up with a building selection menu, and the buildings are the Triton Center and Glass Tower.  Only the lower portion of the Glass Tower was built.  The sim engine is now called SBS (Scalable Building Simulator).  Control panel somewhat works.  Collision detections now work, and user can ride elevators.

Build 208 (11/30/05) - Buildings are now script files in the "buildings" folder.  The rest of the Glass Tower structure was built.
