The real crime is copyright infringement, and this is most definitely copyright infringement. Blizzard used copyright infringement as grounds to sue some prominent SC2 hackers back in 2010, on the grounds that merely loading code from RAM is a replication process punishable up to $500,000 for each count. They won, despite there being no sale or meaningful profit other than advertisements for the host website which actually didn't even cover the costs of said hosting.
Website was taken down, and those folks lost everything they'd ever earned and I'm sure they're still basically ruined. I haven't talked to any of them in a while.
So, yeah, if there's recorded proof of you using an emulator.. much like most copyright infringement, the government has it within their power to selectively destroy your financial life. With the way the government is aggressively collecting and storing almost everything they possibly can on the digital day-to-day activities of regular Americans, I'd suggest avoiding anything quasi-incriminating if you ever plan on being something of a Martin Luther King Jr, or JFK.
I'm sure it'll be fine though. They'll use these open-doors to walk into the lives of criminals who would get away, otherwise.
Emulators require a download (replication) of copyrighted content and injection of code into a host program (another replication within RAM) for each session. If someone wants to charge you, the fines could get pretty steep. The terminology within copyright laws for dealing with this sort of thing is pretty loose, so you'd want a good lawyer to keep things from getting out of hand. That is, if someone wants to charge you. Otherwise you'll be fine, I'm sure.
