I have just compiled myself the latest ScummVM version 2.1.0 git for IOS 11.3 with Xcode.
Everything works fine except Broken Sword 2.5.
After starting the game two errors occur.
The first one is: "Could not initialize color format".
The second one is: "Error running game: Unsupported color mode."
After these two errors ScummVM returns to the main menu.
Is there any possibility to play Broken Sword 2.5 with ScummVM on IOS??
Best regards
Daniel
