Nope. Ruby will be in zer0division.dll. The actual Game.exe will have the absolute minimum possible. Update your SVN working copy, I already added that stuff. zer0 is already being statically linked with Ruby. I just haven't added any Ruby/C++ interface code yet so the library is never actually included for now.
EDIT: Actually I just had an idea. It will be a lot easier if we first made a clone engine of RMXP. We will make Zer0 Division our way, then add the script layer for RMXP script compatibility. Once we have done that and we have a tested engine that works, we can start modifying the engine in such a way that it gets better than RMXP. What do you think about that?
