Plus, there are a bunch of additional things that you don't have to use, but I've added, like material types and all of the FPS/blaster/robot pig stuff (which was inspired by Notch's 0x10c Multiplayer Test).
I even recreated his pulsing highlight shader. Everything is written from scratch in different languages (C#/Unity + Cg/ShaderLab instead of Java + GLSL) without consulting Notch's code, so I could honor my word to Notch.
That is the room editor... It has identical controls, room file format, hardware, snapping, grid size, corner toggling combinations, etc. as Notch's Room Editor, without actually using any of his code (which he asked me not to release).
Currently in the process of refactoring my 2D 0x10c remake from six months back in Unity, is anybody at all interested in seeing the current build or should I wait until I can get something like a DCPU working in-game?
