RetroArch 1.4.1 Netplay

BuZz

@mediamogul I've not revisited the netplay for some time, but since the changes we probably need to adjust our stuff - will look into it.

When "Launch ROM with Netplay" is selected, RetroArch exits back to Emulation Station unrecognized option '--frames'

Yesterday evening I added a netplay_nickname to my all/retroarch.cfg and then loaded up lr-snes9x2010 with Final Fight. I started my own netplay game and updated the list and I could see my nickname on the list. I did not Launch ROM with Netplay support from the Runcommand (I actually forgot to do this). After this I downloaded the database and started it scanning my games and then went to bed.

Thanks, that would be most appreciated. This will be really amazing when operational. By eliminating several of the steps previously needed, forum members will be able to coordinate multiplayer games much easier. Also, the fact that most all of us are using the same distribution through the RetroPie setup, having an identical core won't be much of an issue either. I expect that static IPs and having an identical ROM will be the only hurdles at that point.

It could be that none of the previous steps are necessary to get this new functionality to work. I'm going to continue looking into it a little bit, but finding information has been pretty difficult so far.

How long does it take to scan your ROMs roughly?

mediamogul

@eDrinker

It seemed to take about 3 seconds per ROM. At that rate, the entire NES licensed library of 713 games would take close to 36 minutes.

@mediamogul and by scan I think you mean this screen right?

It hasn't told me it's doing anything but the fact it's frozen I am assuming it's scanning.

Depending how many ROMs your asking it to scan, It will freeze like that for a few seconds (or minutes) then will show you what it is scanning at very bottom. I had it scan all my ROMs from /home/pi/RetroPie/roms/ and I think it took all night. I started it at about 11pm before I went to bed but woke up around 3:30am and it was still scanning. When I got up this morning at about 7:00am it had already finished.

@eDrinker

Yeah, if a folder contains a large number of items, it will pause to account for them all before the actual scan begins. The scanning process will be noted as it progresses by the traditional yellow text at the bottom left.

@backstander

Heh, I didn't see your post there. Didn't mean to re-jibber your jabber.

eDrinker

Thanks both, I'm scanning and guessing a few hours will be needed.

I can also confirm the original journey of launching with netplay no longer works.

@mediamogul
Doesn't bother me. Sometime you can get a bigger picture if more than one person gives their 2 cents.

eDrinker

So has anyone managed to join a game or is everyone still scanning trying to find a compatible person/ROM/emulator?

backstander

@eDrinker
I couldn't connect to anyone when I tried last night but I hadn't downloaded the database yet. I'll probably be playing around with it later today.

eDrinker

@backstander mine apparently finished scanning but can't tell if it timed out. Is there a file saved somewhere with the list. Its a big list and I expected it to take longer.

I only saw one person online and it said no compatible games.

Best of luck, I'm going bed.

Would be interested if anyone gets it working.

@eDrinker

Is there a file saved somewhere with the list.

It will create a .lpl file at: /opt/retropie/configs/all/retroarch/playlists/

eDrinker

I can't get it to work.

I first went to retroarch menu and online updater > update databases
Then back to scan content
This time the ROMs did scan and took about 30 mins to scan 1000 files as it scan files in the folder that are not ROMs as well.

I checked the lpl file and out of the 851 games it only logged around 60-100 games.

To make sure me and a friend had the same ROM and host list picked it up and mine didn't although we both have it in emulation station as an option to play. It didn't appear in my lpl and the file name changed in my friends and didn't match the same naming convention that I gave him.

It always says 100% no matched content and we did have at least one file name and line that was identical.

We tried also connecting via IP through the reteoarch menu with no success. My friends pie would crash PI2 and my PI3 would say failed to initialize.

If anyone got it working or understands how the scanning works and rewords I would be interested to know.

mediamogul

@eDrinker

I'm still a little in the dark myself, but the scanning apparently works on CRC checks, so I imagine that if you don't have the proper ROM set, it may not scan them at all. What's interesting is that this is also the method in which RetroArch adds games to it's own play library. So, I'm guessing that all homebrew games and certain ROM hacks would always need to be loaded manually through the main interface of both RetroArch and Lakka.

If you don't mind me asking and if you happen to know, what system and ROM set are you using to test?

When you say romset what exactly do you need. We were testing a few variations of golden axe 1 and 3

@eDrinker

When you say romset what exactly do you need.

Was it perhaps "No-Intro" or "Good Set"?

@mediamogul no intro
