Network play about mupen64plus-core HOT 11 OPEN

I just stumbled across this open source project: https://github.com/pond3r/ggpo

Do you think it could be used and integrated with mupen64plus?

from mupen64plus-core.

This could be good with 64DD emulation if mupen ever adds that functionality. I know that cen64 and MESS have made huge leaps in it.

Time travel / rollback when?

(I jest. Even desync-free low lag emu netplay is an accomplishment at this point!)

Hello @ymartel06! Nice to see you here! I encourage peoples to test and feedback on this precious development netplay is.

from mupen64plus-core.

Yeah this is great to see. Users have been wanting netplay for a very long time.

from mupen64plus-core.

It would be nice to see following features once you're done with 4 player netplay and udp support:

• Improved golf mode (see aqz-netplay for more info): Make it an extra key instead of using a controller button, would be handy for taking turns in single player games.
• Sync save files before the game starts: an early version of dolphin dualcore-netplay used to temp. sync memcard files, which made it much easier to start a netplay session.

... but even without these features it would be already a huge improvement over the current netplay situation for n64 emulators :)

In my case, the network isn't frame sync by default. So the golf mode isn't needed.
About sharing the memcard files but also maybe the rom, it's an excellent idea but I will work on it when everything will work correctly.
I have pushed some changes this morning and I will keep continue to work on it.

Hi,

It's now possible to play with more than one local player by computer.

To test this functionality, I added a new parameter: local-player.
If it's not set, the default is 1.

So, if you want to do a 2 vs 2, the configuration should like:
mupen64plus-ui-console.exe --server --local-player=2 your-rom
mupen64plus-ui-console.exe --client IP --local-player=2 your-rom

All combinations work like 1 vs 1, 2 vs 1, 3 vs 1... you must have at least 2 players and the maximum is 4.

Another great news, Linux build works (at least compile) now, if someone wants to test and gives feedback, it will be appreciated. The MacOs version should also compile.
I compiled it on Ubuntu 14.04 with g++ without any issues.

I'm currently trying to fix on huge on issue on the windows version.
When we drag or resize the render window, the emulation "pauses".
This issue introduces delay and disconnection inside my network stuff.
I tried to use SDL 2.0 (really easy to integrate it) and I've got the exact same behavior.
It's coming from windows, and I can't find any good solution to fix it.
I read several topics about it and I can't find any good idea.

If someone wants to help, it's welcome!

Great news!

This issue introduces delay and disconnection inside my network stuff.

Maybe a silly idea but wouldn't be a way for the resizer to send a user_resizing to server. This way server hang other sessions (x amount of time max) then resizer send user_resize_done to the server when resize is over.

you need to change the way the video window is created to get rid of the stall.
