(PC) Need help with Dragon Ball Gekishin Squadra

[Naigumi]

Hello! I would love to get some help extracting the files and models from this game. There's some .jpkg files and inside seems to have more stuff

I found one tool that while it does extract some files, it also gave me an error and doesn't seem the files have the right names? Files inside are .skel, .jtex, .mesh and more

Tool mentioned: https://github.com/WistfulHopes/JPKGReader

Sample files extracted with the tool: https://drive.google.com/drive/folders/1gvx3L7ClxfZMMl3-a0ExJST-yeEfAL__?usp=sharing 

Game is free on Steam: https://store.steampowered.com/app/2072560/DRAGON_BALL_GEKISHIN_SQUADRA/
