Same publisher, maybe? Like your copy of Fengshen Yingjiechuan that advertises Chuanpu, Gamtec & C&E games in the manual. That'd explain the "New GB Color" logo they all use too.
IMO TD Software is BBD, or at least related - San Goku Shi Act C has a TD Software boot logo, and its basically just
True Three Kingdoms with a different title screen.
edit: btw I think the bottom left one is the one I have on my multi, the top left one is probably the dumped Digimon 3.
