Skylanders unlocked

I played a ton of skylanders as a kid and though it wasnt perfect, it was a lot of fun. I sold off all my gear though. With dolphin emulator and the vimm download, how would it work to play it again? Do i have to search for the portal and figures again? Is it unlocked and I can use them all without a physical equivalent? I'd obv much rather have it all unlocked, but i want to know my options.
