Guilty Gear : XX Accent Core Plus R Palmods
Accent Core Plus R is the latest revision of the GGXX series, and probably the peak of Guilty Gear in general. Here's a Steam guide about palmodding the game, however most of the resources are behind a Discord server so beware.
These are the pallete mods I've made for +R, you need palmod and installing decrypted character .bin files (Google drive link) to replace the original ones located on "...Resource/pr/ver_100" (this step is important so palmod can open the sprites or it wouldn't work otherwise)
