BACKENDS: WII: SCUMM: Wrong colors for cursor objects in COMI

[dwatteau]

Running Curse of Monkey Island on today's daily build for Wii, the game looks mostly fine, but the colors of the cursors look wrong, especially when doing the following:

1. Start a new game of COMI on Wii
2. Pick up an object
3. Then, pick it up from the inventory

The colors are off, for example some objects appear mostly blue or green, when they replace the default cursor.

I'm not sure whether if it's an engine issue or a backend issue. So far, I've only seen this problem with a SCUMM game, on Wii. But the same game is fine on OSX PPC or PS3, so it doesn't appear to be big-endian related (at least at first sight).
