I played the japanese version of Samurai Shodown IV a lot on my PlayStation 1 back then. I used to be really good with Bust Kazuki and I fell in love with some characters, specially Nakoruru and Rimururu. The only problem is that the loading screens are ridiculously long and the game even freezes for 5 seconds before each fight begins…

Yes, it’s the random selection. Also the reason Cloudchaser is there is because she depicts better the character that is in her slot in the original game, who is in this case Jubei…

What does the recycle symbol mean? Random?
 
Also, Sweetie Belle and Scootaloo, but Cloudchaser instead of Apple Bloom? Huh?
