Baseline (Widescreen) Solution & Issues
NOTE: the aspect ratio handling is based on the current desktop resolution, not the in-game resolution, so if the in-game resolution has a differing aspect ratio everything will be skewed incorrectly. The "show all resolutions" checkbox determines what resolutions are listed (when unchecked only resolutions with a matching aspect ratio will be shown).
Artwork cutscenes have Vert- art with Hor+ text/subtitles. The spaceflight targeting arrow is stretched. Everything else scales correctly for both space battles and planet battles when using a matching aspect ratio (see additional screenshots for planet battle comparison).
Resolutions can also be set manually in %LOCALAPPDATA%\Salvation Prophecy\ogre.cfg (on Windows). The aspect ratio behaviour still applies.

The planet battle HUD is displayed correctly at all tested aspect ratios (see additional screenshots).
