Video documenting the current progress that's been made on TSO-R. The loading is still slow, but that will be improved.
As for networking, it was disabled in this build (revision 77).
The client also supports floor-tile placement, but it wasn't in the build when I made the video, because the other developer, Nicholas, forgot to add a file in his latest commit.
We would have been much further along at this point, but due to internal development hell, we started a build in C++ that was eventually scrapped. There's also been a constant shortage of developers.
Right now the core team consists of three developers, where one is working on another project (emulator that isn't really an emulator so much as a C# client that uses the original protocol compiled as ASM in a C++ DLL).
The current revision is the result of about 2-3 months of work (including networking), plus another month of research (mostly for formats).
