The bug in the manual has been fixed since about 5 weeks (January, 17th/18th).
The 5/6GB H10 has a smaller screen resolution which the invadrox plugin wasn't prepared for yet (the c200s and the M3 have the same problem by the way). I once started doing the graphics and the aliens become really small already and I hit a problem altering the code to deal with the smaller graphic correctly, can't remember the details though. Maybe I'll pick up the work again sometime but no promises

...or at least dig out the work and post it to flyspray.
For even smaller screen, like e.g. the Clips' or the Archoses I think a port can only be possible if you alter the gameplay a bit and use a smaller "grid" of aliens.
