SCUMM: MANIAC (Original bug): walking on background in entrance hall

[GermanTribun]

In all the enhanced ports of Maniac Mansion (Amiga, Atari, PC), there is an original interpreter bug in the entrance hall, which is very easy to replicate. Walk two or three steps up the stairs, then click to the right of the vase to the right, and the character walk through part of the stair railing and the vase. How that looks, see screenshots made under ScummVM.

Clearly the area where a character can not walk was not set correctly (it was set correctly on the C64).

Small edit: That also goes for the vase to the left.

Hi @GermanTribun: could you share a savegame where the character is put at the exact place in the stairs, just before one clicks next to the vase?

(Preferably with the English DOS/V2 release, since most people have that one.)

Because I've spent some time putting Dave at various positions in the stairs, but I can't reproduce this behavior. (I did get Dave to glitch to bit through the gargoyle, though.)

Thanks.

No problem. I did make a save and also a screenshot where to click to cause Dave to walk through the lower pixels of the stairs and the vase. I used the German V2 version, don't have the English one. I know this also works for the left side, but maybe the guide for the right side gives enough indicators.

I also marked another spot with a screenshot. After being further up and clicking there it will screw up the layering with the gargoyle.

Added save and picture where to click for the left side, and a shot of Dave walking through part of the left post. It's not as extreme as on the other side, however.
