I think it's been widely acknowledged that Lang was already finding it hard to improve his programs even in the late 80s, so close results in small statistically meaningful samples are not that surprising. Even if I take his current Windows Phone Genius and effectively slow it down to similar computational speeds that his late 80s Mephistos managed at classical tournament time controls, the strength is still quite close - maybe 30 to 50 points at best stronger than a Portorose.
I also recall reading (I may recall incorrectly), but the original Dallas to Roma evolution was considered to be an extremely small one.
It's all the more interesting that programmers like Morsch managed to make continued improvements right through his career- on the same hardware equivalents he probably squeezed a class and a half worth of improvements.

In the second game came up this position
[fen]R7/4k3/8/6pp/5p2/6b1/4K3/8 w - - 0 1[/fen]
and after 65. Rh8 g4 66.Rxh5 went into a draw position.
Maybe a close match regards
Ricardo
Fourth game at 20 sec/move was a queen opening and ended in a draw. In the end neither Roma or Dallas let the other king go through.

It looks like black (Roma) will win but white played 106.Nxb6, this move leads to a draw. As of course Dallas or Roma do not have EGTB i let them played up to move 150 and they got stuck in a position where black could not make progress with its pawn.
The match ended 3.5-2.5 for Dallas
