Ultima VII

This takes a little bit of thought. There are two resolutions to consider - the "game resolution," and the "screen resolution." The game resolution determines how much stuff gets drawn on the screen, and the screen resolution determines how many pixels are drawn on the screen.

First, determine what the screen resolution you want is. This will probably be your native res. Next, choose a "scale" setting. This is the ratio of the screen res to the game res, and the larger your scale, the bigger everything will appear. This number must be an integer. I find that '2' works well for everything, but feel free to experiment with 1, 3 (if your screen res is divisible by 3), and even 4. This detailed report will be based on using a scale of '2'.

You can simplify the solution by using a scale of "1." If you do this, then the screen res and game res are equivalent. But I find the game is practically unplayable at high resolutions this way, so I don't recommend it. Also, "3" will not work with the 1280x resolutions, because 1280 is not divisible by 3.

Here's where you actually edit a file. Edit the file "exult.cfg." Find these lines:
<fullscreen>
no
</fullscreen>
Set this to "yes". Now find these lines:
<scale>
2
</scale>
Make sure this is "2", or if you want to use something else, set it to that. The solution assumes you use "2'.
Now find these lines:
<width>
320
</width>
<height>
200
</height>
These represent the game resolution. Change the numbers to *half* of your desired screen resolution. For example, if you want 1440x900, you would set the width to 720 and the height to 450. If your scale is not 2, then divide your desired screen resolution by your own scale instead.

If you find that you don't like the scale setting you picked, you can edit this again and use a different scale, but don't forget to change the game resolution appropriately.

=====

All of the cut-scenes behave in one of three ways

Behavior 1: Shrunken head
In the scenes where the Guardian taunts you, the screen is filled with a swirling blue background, but the Guardian's head gets smaller as the game resolution increases.

Behavior 2: Windowboxing
In most of the other cut-scenes, the actual cut-scene is rendered in a 320x200 (relative to game resolution) window, and surrounded by black bars on the rest of the sides.

Behavior 3: Windowboxing with artifacts
This is the bug referenced in "singleplayer anomalies." A few windowboxed cut-scenes show portions of the scene that you're not supposed to and/or garbage where there should be black bars.
