Once unpacked, the current badge pack is located in /region_[REGION]/common/sharc/pc.sarc. This package changes with every update, and badges that were once there may be missing an update later. Alternatively, the game's save data has an archive called allbadge.sarc containing mostly badge files and what might be theme files. Februarysn0w's allbadge.sarc file can be found in the 00001346 folder here: https://onedrive.live.com/redir?resid=B6305612E3C95FBD!694&authkey=!ANwz34EVEYjGARc&ithint=folder%2crar The magic bytes for the badges are 50 52 42 53 (PRBS) and the badge ID seems to be stored at 44 onwards. Below that, the collection ID (Badge ID in the japanese version) is written at 74 and multiple translations of the nice collection name are written starting from E0. The format below that seems to be mostly similar to how badges are stored in Badge ExtData, although I'm not too sure. According to user @nanika , the pc.sarc file from each update contains the badges for the week stored in binary .prb files.
