Retroarch, netplay won't connect
 
Note: I am not a newbie. This just seemed the best place to post this question.

I enjoy playing video games. I posted to linuxquestion.org several years ago and someone suggested retroarch to me. I installed it and I love it. I'm having a small problem with it though at this moment.

I am currently on Slackware 14.2. I do have ten years experience with Gentoo though, so I am (almost) no stranger to building my own software. I am running retroarch 1.7.7 on my Slackware system. Trouble is, all the rooms available through netplay are running 1.7.6. I am not sure how to downgrade to 1.7.6 from 1.7.7

I play Pokemon. I have Fire Red and Leafy Green. I was planning to play both of them, and then connect the two games together through netplay to trade Pokemon between the two games. This strategy is proving problematic for me.

When I try to connect to any of the suggested hosts, I get a message flashed at the bottom of the screen: "\| Failed to locate matching content by either CRC or filename."

I issued
Code:
michael@caitlyn ~ $ retroarch --menu --verbose &> log.txt
And that came up with
Code:
michael@caitlyn ~ $ cat log.txt

None of which is helpful to me. Can anyone out there make sense of this output? Can anyone advise me on how to connect my two games together? Thank you in advance to anyone willing to try.

We can move it to software or games if you like.

We'll see if there are any bites.

Is that IP address one known to you? That seems to be the first problem.

Is there a log you can get on that other system? It may show you information about why it's not connecting.

Yes, please move this thread over to games.

Re: IP address.
I don't remember many of the tricks I used to use in my Gentoo days, but I tried to dig the IP address 99.235.158.141 with no luck
Code:
michael@caitlyn ~ $ dig 99.235.158.141

IIRC, a code of NXDOMAIN meant that the DNS record is not correct. Meaning that I can't get there from here.

The problem description is so specific to retroarch; you say something about version incompatibility (I guess you mean retroarch itself), but don't show us where and how it manifests. Then you also seem to be saying that you are trying to connect two of your own games, and that "doesn't work" either - but they would be on the same version then? So the version incompatibility cannot be the problem?

There's no error messages in the log.

Maybe you can whittle it down to a general Linux networking problem, we might be able to help.

Or wait for retroarch experts.

Or open an issue on retroarch's git repo.

I read on another site (tab it was in is closed now, and it was closed so long ago that it is no longer on my history) that a version mismatch between the server you're trying to connect to and your client version can cause this problem. When I try to connect to myself, the second retroarch window I open has a pure white background, and is not really interactive at all. I try to only use retroarch on weekends, leaving weekday times for actual work. This is why I'm just getting back to you now.
