What is the significance of this statement? If it's your own game, you should be required to capture all of your spells... And what are you talking about? Python script for proof of spell capture?
As the final card in the main game, it's supposed to be a difficult card. I use a Python script to convert language files from .txt to .bin format, the latter of which NTP can read. Unfortunately, credits.bin wasn't created, so the game crashed when it tried to display the credits.
P. S. I captured 9 / 10 of the Normal Stage 10 spells. The ninth, "Salamander and Fox's Black Nightmare Arcame Paranoia", should be technically possible (at least on Normal), but it takes a lot of skill and luck.
