Hi friends, and sorry for finding this thread so late.
This news came as a big surprise for me!

  When I read about this, I thought I should thank those
guys in some way, so I released the C sources of I.N.E.R.T.I.A.
and a short tutorial to compile them. Nothing exceptional, but
might be of some help to beginners. (they are on 'MSX Software'
menu of http://andrear.altervista.org if you are interested)

  I dedicate sources, tutorial and the following motto to Karoshi
and Matra guys for their generosity!

"when you make a gift from the door of your house,
you'll receive back some gift from the window".

Bye,

                                                                    Andrea
