I made a small animation mod for Pepper that changes her victory, defeat, and shield animations. It will be in my profile later today. (I have no prior experience placing files on my profile so I have no idea wheter this will work, but live and learn, I guess.)

Here is your ROM: http://supertiltbro.wontfix.it/files/tmp/smiley09/tilt_no_network_unrom_(E).nes
I just had to change the last frame's duration of the defeat animation. Max value is 255.
I love it. May I reuse some parts in the official game? Notably Pepper's victory/defeat animations 😊️
