--- Comment #13 from David dav75uk@yahoo.co.uk --- Confirming as of wine 7.20 chessbase reader works.
Hopefully you'll be able to implement the arrows now. I'll also check when I get a moment some of the other bugs against chessbase which should be able to be reproduced and hopefully they can be solved too as I suspect many of the bugs overlap (the registration might be able to be tested as you can register media).
It also seems there were a few other issues with chessbase reader than I didn't see with chessbase 11 (missing close and maximum icon in the top right of the window) and it was going really slow as well at one point when opening a game from megadatabase 2018 (which has millions of games) - so maybe I'll open a appdb report on the reader as well.
If you're fixing drawing issues, then the warnings: 0024:fixme:gdiplus:resample_bitmap_pixel Unimplemented interpolation 7 and 0024:fixme:gdiplus:brush_fill_pixels path gradient blend not implemented
have always been annoying but I'm not sure what's missing without them, but maybe a chance to implement them or at least understand them as you can run the app now.
