BACKENDS: 3DS - Blurry text in KQ6

Reported by: MarioKartFan Owned by:
Priority: normal Component: Ports
Version: Keywords:
Cc: Game: King's Quest 6


The 3DS port plays KQVI masterfully. However, from time to time the text boxes on the lower screen display blurry letters. This can happen intra-scene. For example when speaking with someone, the letters will be crystal clear. But as the dialog changes, even if the rest of the scene is unchanged, and even if the dialogue box itself is the same size, the letters suddenly become a blurry mess.

@Mariokart: Can you please add a savegame demonstrating the problem?

And maybe please also add screenshots / photos of the problem.

The issue is KQ6 runs at 640x400 in hi-resolution mode (the SCI engine upscales the 320x200 resources by a factor of 2). The resolution of the bottom screen of the 3DS is 320x240. So the 3DS needs to downscale the game by a factor of 2. For the downscaled game to look good the texture needs to be sampled in the middle of each group of 4 pixels. At some point the alignment becomes incorrect and the linear filtering averages pixels that did not have the same value before the SCI engine upscaled them.

It would be nice to fix the issue in the 3DS backend. However, in the meantime playing the game with the hi-resolution graphics disabled provides a non-blurry experience. The nonsensical situation where the engine upscales the graphics only for the backend to downscale them does not happen.

Hello bgK:

I disabled high resolution graphics in the edit setting, but that does not have any impact on the blurriness of the text, unfortunately.

You also need to select DOS rather than Windows when adding the game.
