The Secret of Monkey Island - Mega-CD vs ScummVM

Post by Wesker »

What's ScummVM supposed to do with the Mega-CD version of The Secret of Monkey Island when running it? Is it modifying it's display or graphics somehow?

I ask this because one prominent feature of the Mega-CD version is that it's dark, very dark. You can clearly notice this when you run the game either on original hardware or any typical Mega Drive/Mega-CD emulator. However, ScummVM seems to light the graphics/colors considerably, making a huge difference in vividness. Here's some pics for comparison.

My wonder is if this is doing something out of reach for the Mega Drive/Mega-CD itself, not possible to recreate when you run the game either on original hardware or emulation somehow. I'm aware there's a trend to attempt color hacks for Mega Drive (and some Mega-CD) games, though this is not the scope of ScummVM. But if this is keeping strict to the limitations of the Mega Drive/Mega-CD, then maybe it would be possible. I have some doubts regarding that point, because you can see the Mega-CD version changes the Guybrush color hair sometimes (like in the harbor scene, see picture), obviously because of color count limitations, while ScummVM keeps that consistent. That's something the Mega-CD version does from time to time, depending on the scene context and its color count.

Well, maybe the Mega Drive/Mega-CD itself can't totally match what's ScummVM is supposed to be doing with it, but surely something could be done with that darkness/grittiness the original game runs to make it more vivid, even if just a little.

What is the reason they couldn't take the colors straight from the Amiga version, anyway?

While this ended up being largely ignored, fortunately the issue has now been fixed when playing the game on a real Mega-CD.

Apparently, this (odd) problem was derived of setting up the shadow mode of palette colours of the Mega Drive as default.
