Help with Puyo Puyo Tetris 2's .pac files?

[Funky Fresh Fellow]

Currently trying to rip Puyo Puyo Tetris 2 sprites with Switch Toolbox. I have the assets and everything, but everything except for the cursor (which isn't in any folders and is in .dds format) is in .pac format, so I feel like I may have done something wrong when extracting the files. I've read that Switch Toolbox can open .pac files, but it doesn't seem to work here, giving me an error message. Any help would be appreciated!
