How come they don't make Project64 online work with Netplay?

I've tried to use Project64k to play online but it doesn't work. Not really the software's fault, its my dialup that makes it lag big time. But lately I've been playing online with ZBattle and I'm experiencing little to no lag. The games play flawlessly except for the occasional mess up which really does not impede gameplay in the least bit... It runs as smooth as it would if I was playing it alone...

and how come Conker's Bad Fur Day Desyncs with Project64k when I try to play it online? How do I fix that?

You can't really. If it desyncs, it desyncs. End of story. Blame Kaillera, its design, and the way it was implemented into Project64 (not to mention that the core is from PJ64 1.4, so I'm not at all surprised if that in itself contributes to the desyncing issues).

Perhaps a faster connection helps. It should, but you never know when "Kaillera" is is uttered in the same post.
