Summary 01858: gijoe: Zooming glitches and a wrong backdrop
Description After the "elevator fixing", GI Joe shows some glitches in the elevator (3rd) level, while grates zoom and scroll down.
Once you reach the end level boss, the backdrop promptly changes to an obvious wrong one (probably because when the zooming ends, it changes in a common tiles background graphics, but it chooses the wrong one), with robot octopuses popping up from...uh from nowhere?
Steps To Reproduce Go to the 3rd level; reach the 3rd level's boss.

Still happening in mame 0.202
The only glitch I see is the boss floor. The boss floor is a different backdrop not seen in the previously uploaded images. It doesn't appear in MAME.
The rest of level 3 seems ok in current version.
I've uploaded savestates for the beginning of level 3, and right before the boss.
Here's a video of the original arcade pcb. Level 3 is in 10:28 . Boss is in 12:30

Runs perfect in mame 0.115 backwards, the floor backdrop is correct in the boss.
I've uploaded a image of it
Regression is 0.118u2, right when the related elevator issue (00484) was solved

it was broken intentionally as the code to support it was one of the biggest abuses of code in MAME (writing directly to the private tilemap cache rather than properly emulating it)
