Yes, I actually saw a screenshot. It's either a hack or genuine, but not a typo.
However, the letter A on the labels of the chips is written in a strange way, with a much thicker font than the rest of the texts. I asked for a clearer picture of the board.
Do you think this could be some kind of prototype or unreleased version? Because if it was used in actual arcades, I assume it would have been known by now, right?
Also, the board is in perfect condition. Totally clean. Doesn't look to me like something that was put into a public arcade.
The board has plastic "feet", even though I don't know if they originally belong to it.
There is one other reference to this game that I found, and that's only in French:
