Measuring GGPOFBA Micro Stutter


How good is it? Where is it used?


In the game he’s working which is in public alpha(Fearless Night).
Me and MightyMar have played each other on it, the netcode is really good.

Edit: It allows a rollback style netcode. Which I should of stated on the first post.


This is normal because the mame rom set updated since the 2008 GGPO FBA release. You can combine your current and and it should be fine.

See here:


cool. i’ll give clrmamepro a try


Besides the lax licensing term of FBA, why haven’t people looked into implementing good quality net code in better emulators like groovymame or shmupmame? Do you think it will be tough to integrate ShobuNetwork with mame as least for p2p style connection without a match making service like


Well each system uses a different savestate setup and some systems don’t even have savestate supported on Mame. So not all games could be supported. If it was going to be done you have to focus only on a few systems at first.


FYI antervud found the vanilla source of

but for some reasons they don’t have

anyway the latest ggpofba is 029674 and they do have the vanilla source of that

I just took a cursory glance of diff between and
It wasn’t too bad but not trivial either.

However the bad news is the diff between and the latest fba_src_029729.7z
They reorg a lot of code. So really need someone very motivated to do the port, given that ponder will give us (which according to license term of fba he should, but he’s extremely busy)


this should be the release immediately after the frame fixes (apparently they skipped a code release to protest against some unofficial versions teams that don’t wanna release source code) ( Release)

maybe this has less code reorganization

you can see captain-cps claim that in this thread

edit: this is the nearest available


You think you guys could modify FBA to run 3S at an arcade perfect level?


Been a few months since I posted any new ideas on how to get ggpo to work on windows 8 yet? Im thinking I may just have to give up the idea of ever playing online again. Tried to play again and its just fucking awful… Super pixly all jacked up, and the lag delay is just awful. Getting hit by jump random jump ins cant even block let alone try to do moves. Bad enough I had to play with a broken controller the before… Time to retire for good at this rate lol Its like even small pings are not equivalent too 200+ it feels liek at least.


Dual boot to XP and hope it’s not as bad, since video card support of older DirectX calls seems to be a major factor in whether and how much it’ll skip frames.


Doesnt that work the opposite way though? Like when I had windows vista I could easily run things in XP or whatever… But this isnt like vista or XP that I put windows 8 on to go back… I got a new cpu and its just windows 8 period. So when I try to change the operating system the only thing I have period on this cpu that I can use is windows 8. Before I could do something but not now. At least that im aware and have tried/fiddled with. =[


It’s still possible, but it might take a bit of time to set up. You’d need a new partition for XP and a bootloader like EasyBCD (free version), as well as making sure there are even drivers for your stuff on XP.


hrmm ill have to look into it. Thanks dudes… What are the chances that ggpo ever gets updated just to work correctly with newer stuff? lol Actually saying that do games play alright on supercade? I actually havnt even tried now that I think about it… rubs chin


I’ve been on Linux for about half a year now and haven’t played GGPO or Supercade in a while, but when I was using Supercade on Windows it was working a lot better for me.


Supercade isn’t bad, but it’s still an old version of Finalburn without the Win7 fixes, tests above show similar skipping problems.

The best chance for any progress these days is for someone to take ShobuNetwork (like Jed mentioned) and put it in a modern FinalBurn to see how it runs.


That’s interesting. I wonder why Damdai hasn’t upgraded it? Is he even aware there’s an issue?


He may not be aware, although Damdai likely has just moved on and only keeps up the server. For the longest time, people refused to even believe this was an issue and just claimed it was scrubs whining until there was a way to show the hard data.




He knows but can’t expect anything especially when he’s done so much already.


You can sort of solve this. Disable global v-sync if you have it and turn off aero for ggpofba (you can set it in compatibility settings).
The fix is to limit fps 2 frames below your refresh rate. So 58 for 60 hz. You can do it with Nvidia inspector or RadeonPro software.

As you can see, there is ocassional jumps in framerate, but otherwise, the is no stutter and controls feel way more responsive, pretty much solved input lag for me.
