Add kaillera netplay support

[mxsymeg]

Is there an existing issue for this?

• I have searched the existing issues

What feature are you suggesting?

https://kaillerareborn.github.io/

Why would this feature be useful?

Hopefully support for kaillera netplay can be added in subsequent releases!

Thanks for the suggestion, however we would prefer to avoid fragmenting the multiplayer population and instead commit to solely using Pretendo.

Pretendo is a Nintendo Wifi Server

Kaillera is a netplay protocol

Oh, I see. Sorry for the confusion. I will reopen this

I've never heard of kaillera before but for what it's worth it looks like this account is just going around spam advertising this project on basically any emulator on GitHub (including some repos which aren't even emulators at all....?)

They're also specifically talking about a new version of kaillera which seems to be made by https://github.com/God-Weapon, the original kaillera (https://kaillera.com) seems to not have had a release since the early 2000s and this new version is just using the same name?

After checking out some of the closed issues, and the reasons as to why, it looks like there's a number of reasons. Including:

• It seemingly is designed for platforms without native netplay? Which the 3DS has already? (source)
• It's not open source, and thus is limited on platform support (source, same as above. Though it seems like this only applies to the original kaillera, not this new thing?)
• Claims about security issues, likely stemming from the closed source nature of things and the apparent spam and it not being the original? (source)
• Claims that it's immature and cumbersome to implement? (source)

It seems like a number of projects have implemented kaillera before, but from what I can tell it's the original kaillera? This new one seems a little sketch to me, ngl (mostly because of the spam), and since the original was closed source it's not super clear how accurate this new version is compared to the original which may make it incompatible with existing kaillera tools? But that's just me, I could be wrong this could be totally safe/accurate for all I know, I just did like 4 minutes of searching
