Thanks for testing it, good to know it's not an emulation issue.
As for the picture from the manual being different: I'm pretty sure it's a mock-up. I just tried the game on MAME for a couple minutes, with my eyes focusing on the right side. You see those border segments with diagonal stripes on them? In the manual, you see 4 on the right side, that never happens on MAME. The maximum is 3.
