From the developer:
ECWolf is an advanced source port for Wolfenstein 3D, Spear of Destiny, and Super 3D Noah's Ark based off of the Wolf4SDL code base. ECWolf pulls a substantial amount of code from ZDoom and aims to provide a wide array of mod editing capabilities without the need to modify the source code. Most importantly you will no longer need to replace entire data sets.
