Note: The sprites here were mostly taken from the files in the 2nd game, but they should be accurate to the first game. It's just that I couldn't get the file format from the first game to display in any proper way using my very limited knowledge. I tried my best.
Sprites were extracted using Tinke & GLIntercept. Sprites extracted with Tinke were further edited in Clip Studio Paint.
