Subject: [PATCH] == game engine: save as runtime ==
- solved the problem I had with this addon, finally
the addon was saving the blend as it is and in my case a compressed blend file was giving problem when played in the runtime
- hence added a bit to manage compressed blends to embedd them uncompressed
NOTE: this should be fixed in the player itself I think, same says campbell, but worth checking
- now moved to trunk :)
