Most chess-playing computer programs have a "book" in the software that lays out opening lines for the program to play. This saves on computing time - i.e. why analyze the "best" 6 or 8 opening moves, game after game - and makes sure that the program gets off to a reasonable start. It can include the latest preferences of super-Grandmasters, or the favorite moves of the programmer.
Given that the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is not likely to be deemed "best" play for White by the analysis of any competent computer, any time the opening is played by a program, it is likely that the Jerome has been included in the opening "book".
A computer program dedicated to playing the Jerome Gambit - like Brause, focused on the Halloween Gambit, mentioned in an earlier post - would be a gift to the Jerome Gambit Gemeinde; but, alas, such a thing apparently does not (yet) exist.
I cross-checked the list of 130 or so computer "players" at the Free Internet Chess Server with the roughly 55,000 games in The Database. I found 9 additional (see Part 1 and Part 2 for the games of GriffySr and GriffyJr) games showing a variety of Jeromes - the Jerome Gambit proper, the Abraham Jerome Gambit, the Blackburne Shilling Jerome Gambit, and the Semi-Italian Jerome Gambit.
