Summary 05919: thoop: Sprite priority bugs with background objects
Description I seem to recall a few points in which the background objects should cover the sprites. See the attached file section for details.
Steps To Reproduce Reach the parts listed below.

Level 1:
1) roughly 1/3 of the level - the lake of acid with the rising/lowering platforms;
2) roughly halfway the level - the part with the dashing red demons on the grate;
3) the end of level boss, upon entering its room;
4) after defeating the boss, when the character jumps in the sewers;
5) the screen after level complete.

Level 4:
6) roughly 3/4 of the level - the part with the trees in foreground and the monsters that rise from the terrain.
Additional Information Marked as possible, since I found no PCB videos on the internet, and it's been 20+ years since I last played a thoop machine.
EDIT: finally found a PCB video; removed the Possible flag (still not sure about point #6, but all the others are confirmed).

Flags Verified with Original

The 1st boss should be completely hidden by the red container (and thus invisible) when you arrive in its room

After defeating the 1st boss, the character should be hidden by the background when jumping thru the container

FWIW switching from screen_update_maniacsq to screen_update_bigkarnk fixes all the problems but nr. 2.
