No Andrew. Only one version.

The 3D routine uses Sock Master's "Gloom" engine algorithym. The way 
that works is to scan forward and outward in a semi-circular pattern 
depending on the direction you are facing.

My algorithym is very course because I was trying to get enough speed to 
utilize the engine for a complerte game.

This method gives a bit of a "fish-eye" lens effect. The same can be 
seen in Sock Master's higher definition Gloom demo.

A better method would be to do a squarer forward scan than radiating out 
from a central point.

The reason one screen shot looks different to the other is that it's 
dependant on the distance you are from the walls and the angle the walls 
are to you. Sometimes the walls look straight while other times there is 
a very distinct curve.

Rem's "Wolfenstein 3D" demo has an improved algorithym that counters this:
