Description

While the high internal resolutions which didn't quite make sense are gone now, it seems medium resolution (640x200x4 color mode) is broken. You can see this when you're setting the desktop to it or any game - Magnetic scrolls adventures, Empire etc. It seems the core always assumes low-res (320x200x16 mode, with PAL borders 416x260).
For that reason I'm also puzzled about the high resolution option, I would think it should let you boot into 640x400 mono mode, but it doesn't seem to do anything.

Research direction

Start by reproducing the issue on Windows by selecting the 640x200x4 medium-resolution mode for the desktop or a named game such as Magnetic Scrolls Adventures or Empire. Compare its behavior with the stated 320x200x16 low-resolution mode and investigate why the high-resolution option has no visible effect; done means medium and high modes use their expected resolutions and borders.
