EDIT: Update, I found this, but sadly all download links are gone. https://web.archive.org/web/20050120154624/http://www.ourfamilysbox.com/~meunierc/tvnw/ But it shows screenshots of the Loto-Québec chess game.
Well damn, an actual dump of a Videoway game, the only one known actually !
Nice find !
Sadly, it seems that the link to Echec was dead since 2004 or so.
The page mentions this though :

Which means that TVWM should be found on his older website, as ourfamilysbox.com only appeared around 2002 or so.
You can try to bug him on Twitter
DJ or on LinkedIn
too as an alternative.
