I extracted (More like downloaded an already extracted rom) a monster hunter tri ultimate rom and i got these .arc files, though i dont know how to open them...

Ive googled, searched everywhere for a solution but to no avail, does anyone know how to extract the models/textures for this?
if so how? and programs i can use?
