Ripping models from Mario Party DS and MySims Party [.bin Files?]

Mario Party: "Daisy"

MySims Party: "NPC Body"

"Character Icon"

I need help on opening these .bin files. NPC Body is probably model data, Character Icon is probably sprites, Daisy is probably both.
I have no idea how to open these files > I've tried every way I can but cannot find an honest program that opens bin files like it says it can. I would really appreciate some help with these.
