for this, and in particular, it now sometimes stalls in a way that makes it very difficult to actually input anything (whoops :) ). Simply setting the sync frames higher avoids that. With supported cores, this is incredibly risilient, but when it fails, it mostly fails to freezing, which is less than ideal. TODO: Stall frames should be configurable. All the UDP code is still there but commented out, should be gutted. The original fast-forward code is now commented out, but really both fast-forward and stalling should be options; the only complication is that it needs to send simulated self-input for fast-forward.
