File a lawsuit against a John/Jane Doe defendant(s) and describe who the defendants are, e.g., the people who code and maintain the emulator. Maybe a little harder than if you had the names but not by a lot.
I should say: the real difficulty is service, but if there's any way to get in contact with you, there's at least a chance it will be accepted as good service. There was famously a recent case where a defendant known only by a Bitcoin address was served by sending a transaction with an attached message to that address.
