Major suggestion for PC

I have all my s1-s3 stuff which is fantastic, now the only thing that needs to be done is pure offline support. With the local Tournaments I host I’m planning on bringing my pc, I do not however, have a wireless option or an adapter to use. My PC having no connection to the internet whatsoever locks out all but one character to the system, the freebee. I think the best option for this is to not have DLC on the cloud but actually put it on the PC instead.
