Screenwidth / centering bug #3

Open dfilskov opened 4 years ago

dfilskov commented 4 years ago

It seems there a bug in the via-i emulation regarding screen width near max possible (on PAL at least) when the "centering" option is selected.

It appears in the Dragonwing game: https://www.dropbox.com/sh/820f5e07f8x74ou/AABym7TIw5gdgODXNNATgiufa/Dragonwing?dl=0&subfolder_nav_tracking=1

No centering centering none

Vertical centering centering vert

Horizontal centering centering horz

Both horizontal and vertical centering centering both

centering option is enhancement not present in original HW. It's possible some games use unexpected settings. So simply disable centering for such games. It's not universal solution.

Oh, so please consider this a suggestion and not a bug :) Perhaps it would be best to turn off this unofficial enhancement per default so that all games (and demos?) work with the default settings?
