Summary 08000: yachtmn, mermaid: missing or misplaced graphic animations
Description There is a sequence on level 3 where the player gets attacked by walruses or sea lions. I'm not 100% sure what they are supposed to be. In MAME these animals are static sprites with no animation. On the PCB they do a flip animation in the water and also whenever they cross land.

There is also a bug in MAME where the large wave animation randomly becomes attached to the RANK text in the sidebar. It stays there until the screen is redrawn. This is not supposed to happen.
Steps To Reproduce Play until you see the sea lions on level 3.
Or load the attached 7.sta in MAME 0.231
Then refer to the PCB video timestamp below to compare.

The Rank bug is difficult to predict.
 Just load the attached 9.sta in MAME 0.231
Additional Information Recent long play video from Yachtsman PCB.

00:08:57 is the timestamp for the missing animations.

Attached screenshot of the flip animations from the above video:

Also attached enlarged snap of the Rank bug. There does not appear to be any race condition or rank position that triggers this bug. I have had it happen at all different times, ranks, and levels.
