Since v0.3.29, Menu:draw sets the black text color only inside its title branch, where the title's white backing is drawn. A menu without a title, such as the Red/Blue/Yellow main menu (CONTINUE, NEW GAME, OPTION), printed its choices in whatever color was current: the white the box's fill and the previous frame leave behind. Tile glyphs are black on transparent and come out black whatever the color, so English never showed it, but a translation's TTF font draws in the current color and printed every choice white on white; only the tile cursor stayed visible.
The choices are now drawn after an unconditional black, as before v0.3.29, with or without a title.
