How to change images appearing in game

[Kr0M]

Naruto x Boruto: Ninja Voltage is shutting down soon, and we'd like to save all of the artwork that was available during the games lifespan. These images are not stored locally, so we have no way of finding them without hacking them in.

These artwork appear on different cards, many of which are unobtainable currently. Someone else in the community who has some experience with modding told me which method is used to set the images, which i've attached below.

If someone could guide us through this process that would be extremely helpful as I am basically a complete newbie with gameguardian/modding.

Thank you.
