MANIACNES: Graphics glitch on intro screen

Reported by: fingolfin Owned by: fingolfin
Priority: low Component: Engine: SCUMM
Version: Keywords:
Cc: Game: Maniac Mansion


The very first screen MM NES shows you, i.e. the intro screen with the big tree and the meteor, contains graphic glitches; in particular, parts of the tree are drawn incorrectly. The attached screenshot exemplifies this.

Reproduced with latest SVN as of today (rev 25604). Confirmed to not happen in the original.

Ticket imported from: #1660550. Ticket imported from: bugs/3069.

I'm not seeing any difference between the attached screenshot and Nestopia, other than possible artifacts introduced by the graphics filter you're using (looks like supereagle or advmame2x).

Are there still glitches present when using the 1X/2X/3X filters?

Yes. The glitch (i.e. the off-color squares around the tree) are present independant of the scalar (I fail to see how a scaler could possibly introduce off-colors squares in the first place, anyway -- unless it's a very very buggy scaler, of course :).

The problem was caused by "bad" palette data. Fixed as suggested by quietust on iRC.

In fact this fix was wrong, and the described "glitches" are intended. See bug #2846887.
