Delay frames denote the maximum number of frames RetroArch's libretro cores will need to emulate at once to maintain synchronization due to actual network latency. You can figure out an appropriate ballpark for this number by pinging the other player and dividing the time (in milliseconds) by 16 (roughly the number of milliseconds in a frame from a game running at 60 fps). If the gameplay is a bit choppy, try increasing the number of delay frames a bit. | Delay frames denote the maximum number of frames RetroArch's libretro cores will need to emulate at once to maintain synchronization due to actual network latency.

Similarly to the GGPO platform, RetroArch creates a constant stream of savestates which, along with button presses, are exchanged and compared between the server and client machines. If the savestates start to diverge, the game rolls back in time to a point where they both agree, and then the libretro cores emulates the missing frames all at once to get back to the appropriate spot. This gives the illusion of completely lagless inputs, which is invaluable for twitchy, fine controls. | |||
If you try to connect to a server and it immediately says client disconnected, open your log and make sure your ROMs match exactly (it will complain about a hash mismatch otherwise). If it gives you a weird time-out error, just close the window and try to connect again, and it should work itself out (sometimes excessive spikes in network latency can cause the states to diverge catastrophically, resulting in this error). | If you try to connect to a server and it immediately says client disconnected, open your log and make sure your ROMs match exactly (it will complain about a hash mismatch otherwise).
