Duplivert not visible in game engine (2.49)

When using the Duplivert tool, the duplicated objects do not appear in the game engine. They render fine, however. Does the game engine not have support for duplivert? or is there a setting that will make it visible? If duplivert is not possible in the game engine, what would be a better way to make 3-Dimensional looking grass, while still being relatively fast? Thank you in advance.

The game engine supports only some modifiers, constraints etc, and so things like the duplivert might not work. What might work though is using alt+c, which converts the selected object into a mesh. Although I haven’t tried it with duplivert it works with other things like text.
