(I'll add onto the post as I find things)
"Giving up sins" returns you to 2 lives but you maintain your fractional 1-ups, so it's kinda inconsistent
Defeating the naginata doll with Bird Slam causes both it and Gaji to repeat their post-fight lines like 5 times each. Haven't tested this with other match-end dialogue
Bow 236H "Butterfly Heart" seems to have been replaced with a 3-hit horizontal arrow, but this doesn't guard break an enemy weak to Butterfly Heart. The card for 214H "Arrow Storm" seems to have the wrong input written on it — it reads j.236H
Attempting to start a bout with the "Nobody" enemy on point crashes the game. Enemy kills added to your history by the Num0 cheat don't save to the file, meaning you have to do it after every program reset
214L can be done during match intro to reveal enemy cards
The samurai to the west and east of the bridge arena are possibly a little too healthy — or at least maybe shouldn't be quite so easy to hackeysack around if they're at risk of drifting into an arena activation line or a stage border, respectively.
