dude.......too much time......waaaaaaay to much time as for the bosses, without the other bios file you can play as chizuru and kusanagi, the codes are pretty tricky but they do work im sure they have probably already been posted but obviously peeps dont wanna read all the pages so i'll post em again Chizuru : Up, then turn counter-clockwise to up-right then from this point, turn clockwise to the down-left and press A,B,C, or D. Kusanagi : Down, then turn clockwise to up-left then, counter-clockwise to the up-right and press A,B,C or D. it sounds flocked but its not that hard, if you have a control pad just do it all in one motion, i just press down then roll the pad up to diagonal upleft then back around to diagonal up right and press one of the buttons(thats for kusanagi), you can do it from anywhere on the character select screen, you dont get confirmation that you have done it right until you actually press the button, so the icon doesnt change until you have selected, but i have tried both and they both work fine.....hope this helps
