Ciao sì, è possibile giocare online se rispetti le condizioni.
Ti ho messo il link della Guida Netplay.
https://github.com/recalbox/recalbox-os/wiki/Netplay-Guide-(EN)
La guida non esiste nella versione italiana, se hai la possibilità di tradurre grazie per avermelo detto.

Puoi anche venire su Discord se hai bisogno di aiuto per il netplay, Strodown e io ti aiuteremo.
scusami per il mio italiano vado da un traduttore

@Gamer35 scrappe et hash obligatoire pour le netplay
@Fishou et non la doc n'est pas si vieille que ça et elle est toujours d'actualité!!!!

Quelq'un pour m'aider?merci

@zyrh Did you follow the Wiki instructions?
https://github.com/recalbox/recalbox-os/wiki/Netplay-Guide-(EN)

@Buhmann @joinski The netplay works more or less depending on your connection and other factors.
I put you a link to a netplay guide and also a list of netplay compatible games.
https://github.com/recalbox/recalbox-os/wiki/Mini-How-To-(EN)
The list of compatible games is under construction.
Do you use no-intro roms?
If you want I can help you solve your problem on the recalbox discord.

@elgregou pas du tout d'accord avec toi
moi je n'ai aucun soucis pour le netplay

@Sub-Zéro tu peut toujours venir sur discord pour que l'on check ensemble

Ne pas oublier que les roms no intro aussi on des maj, le dat est disponible sur https://datomatic.no-intro.org/?page=download

@samkrow12 à mon avis tu es tombé sur un technicien qui ne s'est pas creusé la tête plus que ça... oui qui te cache des choses parce qu'il n'a pas le choix. Merci Sosh.

Use this tool, to check, if Netplay TCP Port (should usually be 55435, if I'm not mistaken) is open:

@paradadf enterado. Muchas gracias.

La rom est bien la même car nous avons bien échangé le même fichier , mais par contre je ne pense pas avoir scrapper du coup je regarde ça et donne le résultat.

@substring @barbudreadmon je ne vois pas de quoi tu parles désolé

I have the same problem. Don't know how to fix it.

I'm also testing the netplay functionality and i am not able to get it running. I have 2 PCs with Recalbox 18.06.27 (x86_64), both with identical settings and roms and connected to the internet.
When i start the host on the first PC and try to join from the second PC it always says:
"Failed to initialize netplay."

I tried with catsfc and snes9x (no snes9x_2010)
I scraped and hashed all my roms
And in Netplay Lobby i get the green Ok result (Rom and core match).
But still it does not work ("Failed to initialize netplay" on the PC that tries to join the host).

++UPDATE++
Problem solved! It was the UPnP-Settings in my Router. I activated UPnP and now it works :-)
