That, and we still don't really understand the hardware enough to get emulation working. And it'd require a big rewrite to support this. But there'd be a large performance overhead emulating two DSes, even where you could get away without emulating video and such on the other one. This would allow it to be used over the internet to some extent, especially if the use is things like trading Pokemon. What I think is the best potential path for NiFi emulation is the same that I think is the best method for Gameboy and GBA link emulation: emulate two instances of the DS on one machine and synchronize button presses across the network instead of the NiFi connection (with the NiFi connection emulated locally). I think even if we could get that working we wouldn't be able to emulate it well with a direct connection because the latency requirements are so ridiculously high. It was our focus to try to get it to work somehow because of the Nintendo servers closing (but this was before the custom servers), but we haven't been able to get it to do much in emulation, and we couldn't even get a tunnel working with DSes in the same room going over a wired ethernet and shielded DS compatible wifi dongles. And I don't think DeSmuME's support for this works yet. The other mode is where multiple DS's talk to each other in close range, which I've called "NiFi." This mode requires an extremely low latency connection, and uses a lot of hardware features that aren't completely understood. DeSmuME supported this way back when although it was pretty buggy, but I hear it plays a lot better with the custom servers (makes sense since they can willingly optimize both sides for it) This is supported by something like a few dozen games. One we'll call "infrastructure", where it's used to connect to some Nintendo server. Nintendo DS's wifi hardware has two use cases and a bunch of different modes to support both. He probably knows, he just said that emulation wasn't perfected, which I think is probably pretty accurate (I'd say it's still nowhere close). Now that the nintendo wifi servers are closed we could take advantage of the wiimmfi ustom server. They soon removed it because of repeated attempts of nintendo to block them. There was an SVN revision in the 3000s od desmume that had working wifi. Beansta wrote:Thats where u are mistaken.
