If you want to become a mod creator rather than just a user, you need GGS. You need it to extract the original KONAMI textures to use as templates. You need it to check the alpha channels for sleeve logos. You cannot reverse-engineer kits without it.

PES 2013 was released in 2012 and marked a significant turning point in the series. Game Graphic Studio, led by renowned game director, Yoichi Erikawa, and creative director, Hideaki Itsuno, set out to create a game that would surpass its competitors in terms of graphics, gameplay, and overall presentation.

While Kitserver 13 became the preferred method for easy kit-swapping later in the game's life, Game Graphic Studio was the "hardcore" method. Modders would use GGS to open cv_0.img and search for unnamed_53.bin (which often relates to kits) to inject new designs directly into the core game files. Similarly, for faces, advanced users would edit the faces folder in kitserver\GDB and use tools like PES2013-Editor to map player IDs, but GGS was essential for converting the texture files into the correct format.
