Both of you must run the same version. Is that the case ? (just asking)

yes. we have had no problems with desync running 1.36 or 1.42, but when we tried switching to the new netplay build to support games that had problems in 1.42, games are anything but playable.

Did you try games that worked in 1.42 too ?

aminalshmu · Post by **aminalshmu** » Thu Sep 08, 2005 3:02 pm

okay, this is strange.

we played top gear 2 last night for maybe 45 minutes with no desync at all, when it was previously completely unplayable. i thought this may have been due to us talking over skype while we were trying to play it the first time, and it was causing net congestion, but this is not a problem in 1.42 as we do this all the time - with other games, i mean, since top gear 2 does not work in 1.42.

however, secret of mana and uniracers, which both work flawlessly over netplay in 1.42, refuse to load in 1.42n and just freeze the emulator. no messages in the console; it just stops responding on both machines, regardless of protocol.

Please retry these games after setting the save setting to NONE (not 'local' nor 'remote') in the chat window.

I'm using the official release of 1.42, and I have very few problems with it when I play it over our LAN. Except for the following:

Secret of Evermore dysyncs so much that it's practically unplayable. It seems to do this most often when enemies or moving people are in the area. Its been doing this as far back as 1.36.

Tetris Attack dysyncs sometimes during gameplay, but it's fairely rare.

Kirby's Dream Land 3 dysyncs when you reset, I think. Not sure about this, but I noticed that all our dysyncs started after a game reset.

I've tried playing a LAN game using 1.42n, but ZSNES always freezes when we load a game or change the latency. Odd.

kirby, try this... the save files from 1.42 are obviously not compatible with the 1.42n based on newer WIP's. (at least not in netplay - they load in single player just fine...)

or am i misinterpreting this and the way zsnes 1.42/1.42n handle saves is the same? is it just a problem with 1.42n loading save data period? hmm... experiment time.

Same error. When I load a game or change the latency, the screen goes black and it says on the ZSNES 1.42n window "NO MOVIE PROCESSING." Any ideas?

Oh grr, if that means what I think it means...

So, with 1.42n...sounds nice...does it support quicksaving over the Internet? That never worked for me with 1.42...on a LAN, sometimes, but not over the atlantic ocean.

aminalshmu · Post by **aminalshmu** » Thu Sep 15, 2005 2:36 am

quicksaves still freeze ZSNES 1.42n for me... and setting save data to "none" allows SoM to load, but as we are unable to continue our game, it doesn't really help... back to 1.42 for now.

NightingaleNT · Post by **NightingaleNT** » Thu Sep 15, 2005 3:11 pm

yeah, quicksave didn't work....damn it >_< The one feature I wanted....oh well. *roots for developers to get it working*

Joe Camacho · Post by **Joe Camacho** » Thu Sep 15, 2005 6:09 pm

AFAIK, using savestates is something that's frown upon during netplay, usually causing desyncs. So I don't really think that's a feature that's on the priority list.

Post by **grinvader** » Thu Sep 15, 2005 7:39 pm

Well, there's no reason not to make it work in the new netplay code.

We would probably compress the states so that transfers won't be long...

Nah, plain GZ. JMA is slower on compression for files as small as these.

Doesn't always even transfer for me...sometimes it just like auto presses escape, taking me to the chat menu, and when I try to go back it freezes....;_;

Weird thing, when I try to use savestates during netplay (1.42), they transfer just fine and don't freeze Zsnes or anything, but they don't load on my end. They load on the other player's end though, and thus cause about the most incredible de-synching imaginable.

Fun.

Cheesy_Pie · Post by **Cheesy_Pie** » Thu Dec 01, 2005 3:09 am

Can't help but notice this, but is this still a persisting problem? My friends and I never experienced too many problems on Netplay. It desyncs here and there, but nothing a state reload can't fix. Other than that, it wokrs perfectly fine, both on UDP AND TCP/IP (and I have to use the latter with another friend with dial-up because we can't get the UDP to work with her for some reason)

Just about all the games work (with exception to all the Super Bomberman games, which I find strange. When we bring up the latency it works fine, but then my controls are lagged by a second)

Is there any kind of system information I should post to help on this situation?

I just found it odd that after literally months of no problems with Netplay, I get on here and find out "Netplay is dead" after noticing the latest WIP has no netplay.

And yes, we're using version 1.42

Hyos · Post by **Hyos** » Thu Dec 01, 2005 3:24 am

I believe Netplay is dead in the WIP versions.

adventure_of_link · Post by **adventure_of_link** » Thu Dec 01, 2005 6:10 am

You can always download the 1.42n, which is based off 2/12/2k5 though...

Hyos · Post by **Hyos** » Thu Dec 01, 2005 5:28 pm

I was referring to the post above mine, which mentioned Netplay works in Not-WIP. And then ... I overlooked the last sentence. My bad.

What I should have said:

Netplay is dead because an overhaul was necessary. The devs know the details of what has to be done and tested. While it is being worked on, I believe the devs will ask for specific info themselves.

ok im not very good with this emulator stuff but this is what happened and i need some help

first i was on 56k and my friend was on wireless on v1.42 and it worked fine except that i probably lagged from my 56k

then i get on my wireless and my friend was on his wireless and all of the sudden it didnt work when we use udp connection it just sat there and when we used tcp/ip connection it said Could Not Connect To The Other side or something like that. We checked our ip's and they were right but for some reason it didnt work.

Could someone please help me?
