In my repository of published disc magazines, I read in German Disk-Fan 12, issued in February 1991, from a planned Konami game called "Himmel und Hölle", which was probably meant for the tR.
Did this remain a rumor or does one of you know details about? I knew the author, Peter Zorn, who had many contacts to developers but has died long ago.
A minor correction: "Ten to chi to" in German would be "Himmel und Erde".
The game would be a tie in to the movie Heaven and Earth.
Turbo R would have helped speed up this strategy game, so Peter Zorn's info isn't that far off.
