If anybody is interested in this Submarine sim, I have got the latest svn working with:
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) IGD x86/MMX/SSE2
OpenGL version string: 1.4 Mesa 9.0.2
OK, there are a few tweaks, and bridge/periscope views are sloooooooow (0.2 fps) but other than that it, it is playable in real time.
