RetroArch/runloop.c
Gregor Richards 45d732a014 New sync system 
The idea:
   * Use a fixed number of delay_frames (eventually to be fixed at 120,
     currently still uses the config variable, 0 will still be an option)
   * Determine how long it takes to simulate a frame.
   * Stall only if resimulating the intervening frames would be
     sufficiently annoying (currently fixed at three frames worth of
     time)

Because clients always try to catch up, the actual frame delay works out
automatically to be minimally zero and maximally the latency. If one
client is underpowered but the other is fine, the powerful one will
automatically take up the slack. Seems like the most reasonable system.
