I have a bunch of .arc files from this game's filesystem and they look like they contain all of the game's assets.
I'm particularly looking to unpack one called "datasets.arc" as I'm looking for the model files and its textures, possibly even the rigs.
I've tried using standard Yaz0...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
