At first I thought it is some ordinary MMC3 board, but the pinout does not follow any known version. What is more interesting is that both mask roms have address lines wired up to A18 and none of the official games is such big. So maybe this is multicart?

I am waiting for the response from author of this post, but meanwhile do you have any idea what game and mapper can it be?
