 Thanks for your report!

 The GOG and Steam versions of GK2 include patches to the game scripts that
 disable black-lined video, so the ScummVM GUI toggle does not do anything
 (the game never requests black-lined video).

 You may try moving/renaming `11.SCR`, `11.HEP`, `34.SCR`, `34.HEP`,
 `36.SCR` and `36.HEP` in the `PATCHES` directory to restore the original
 video playback code, which will make the toggle work, but this isn’t
 really supported and may cause other problems.

 I am still evaluating whether this is something that we can/should deal
 with. Unconditionally forcing black-lined video when the option is enabled
 would incorrectly render if someone chooses to use “little movie” mode,
 and I don’t know if there are other places in the game (or in other SCI32
 games) that intentionally did not use the black-lined video flag even in
 “big movie” mode. Also, games provide brightness boost information in
 conjunction with the black-lined video flag to try to partially mitigate
 the fact that the black lines make the video darker; if the calls don’t
 include brightness information, then the videos will render too darkly if
 we force it on.
