As I said before... This is a real frustration to see these sprites (including customs) in these fake screens and knowing they will never be part of an actual Openbor game.
I think no one (coder) have enough interest to make it happen... Very sad, because with all the years they never found a use.
By this frustration, I initially tried to combine some of these sailor sprites into one badass custom Sailor inspired character (more oriented in brawling/wrestling) It was for @danno 's NightSlashers project, but eventually I had to stop it because the color/palette work was too hard to handle to me. (I can only sprite. Other tasks are too hard/long for me)
Anyway, I really regret I cannot find a use of them, without having to color fix, or code something by myself.
