Yes Cammy, that is the thing is I did not change a thing.
I was being an innocent little lamb, trying to add in new games for ScummVM. I had loaded up Day of the Tentacle and set it to full screen when I first noticed this.
At this point I presumed that the game itself did not like the settings I had chosen, so I played with other full screen settings only to get the same result. I then settled for Windowed mode then tried to add another game only to find that I had the same issue.
So then I loaded up a game that I had already configured and tested in Full Screen mode only to find that it now had display issues as well.
Logically, I took a step outside of ScummVM and tried out Giana's Return, only to find that it now had display issues which it did not have before. Before it displayed as it should, well as it should I guess in the limited Amiga environment, where in you get to play the game in a little box in the upper left hand corner of your screen, but now it is just all scrambled graphics that take up the entire top half of the screen.
Of course I could just play Giana in Windowed mode, but then I have to lean real close to the screen to see what I'm doing, even in 2X.
So anyhow, I did try different screen modes, well those which I seem to be limited to because if you try to set your eMac to anything below 1024x768 you won't like what you see when you reboot, or should I say,"don't see".
Of course maybe I'm doing something wrong in regards to adjusting the screen modes, but I wouldn't know because I've never received any clear help in regards to this when I've posted before about it in the forums.
As for the scrambled graphics in full screen mode. Well your guess is as good as mine. Like I said, I didn't change a thing, I didn't add a thing, etc. Unless of course by adding DOTT to ScummVM I have somehow unsettled MorphOS's equilibrium.
So there is my rant, I'm not trying to piss on the MorphOS team's efforts, it's just that little issues like this tend to piss me off, and I must say again that I dearly miss the classic Amiga Prefs drawer. It was so much more clear to understand and work with.
