Beta 0.6 is now up, download link in OP! Apart from bugfixes and an icon (on Windows, anyway), the main new feature is that you can now actually see where every file is used. Hope that'll prove a useful idea
I made a project for it at Google Code and committed the source there (link also in OP), with MSVC2010 project (wxWidgets 2.9) and Linux make things. Now here's a (probably) silly question: I check it out under Ubuntu and I can't run the autogen.sh script. "Permission denied". What am I doing wrong? I can compile FSO from SVN just fine, so I assume I did something wrong in the project SVN settings?
I put this on SVN so y'all can contribute if you feel like it; the main to-dos are multimod, VP support, and cleaning more stuff.
Droid: this version should recognize thruster particles correctly, if you remove the extensions in the table.
