Netplay does not work [$50] #127

Open hooby3dfx opened 7 years ago

hooby3dfx commented 7 years ago

This issue is intended to represent the problems related to netplay on this core when running on a RPi3 & equivalents. I will be putting a bounty on this!

Problem 1: Crash when starting netplay host Found on Lakka 2.0 / Retroarch 1.5 Can be reproduced by starting any psx game after starting netplay host. Before any client even joins the emulator will start lagging heavily for a few seconds and then crash. "Killed" is printed when running retroarch -v when it stops.

Problem 2: Performance likely to be slow State save/load should be optimized so that netplay is possible and not laggy.

Problem 3: ?? There are likely to be other issues related to netplay...

does rewind work? try with skip bios

hooby3dfx commented 7 years ago

When rewind is enabled the game starts slowing down but it does seem to work. Skip BIOS is already enabled by default.

Try increasing your latency frames in the network/netplay settings to something near/above the actual latency between you and the other player.

It lags exactly the same on the raspberry pi 3 as well. I think it's a retroarch issue.

Darknior commented 6 years ago

Arg so bad if this feature not working fine on PSX :( I think rewind must be desactivated on network play, so strange to use it with a friend not here with you, and i don't know how his LR will understand a rewwind action ?

ghost commented 6 years ago

The rewind option is disabled as default on the raspberry pi 3 and still lags. There's no option to skip bios.

ghost commented 5 years ago

there is a Reset() call inside the loadstate function, removing that should make rewind work. also did netplay though its slow and desyncs alot, it works.

is there a callback to know if libretro is running in "netplay" mode?
