Afaik most M72 boards can be romswapped to any other M72 game.
for example my Gallop is converted (romswapped) from another M72 game that i cant identify but it's possible to see it's "license seal" beneath the Gallop sticker.

Here is a pic of it and if anyone recognize the sticker that can be seen under the gallop please tell me :-) i don't want to remove the sticker just to see it.
