P2P Netplay Emulators

Sferics · Post by **Sferics** » Thu Jan 31, 2008 5:08 am

I am curious to know, what other P2P netplay emulators are out there? Google-ing didn't turn up much, so I thought I'd turn to you guys

. Thanks in advance.

Netplay by definition is player to player for the most part... though the network model isn't guarenteed to be such.

Apparently the new version of PCSX2 has netplay, though I'm not sure if it works properly at all. Aside from that the emulator is far from complete and requires a Core 3 Octo @ 8.6GHz, 16GB DDR3, and 4 GeForce 10800 Ultras in quad SLI. It's a hell of a lot easier just to use a real PS2.

What terrifies me is that I'm not sure this is an exaggeration.

Cyrus must have misread. This thread is about P2P Netplay emulators, not PS2 Netplay Emulators.

Heh. The op wasn't exactly specific on what P2P is (it isn't a favorable Google search tearm).

I'm not sure if many netplay capable emus do Peer To Peer networking.. as that isn't the way to go if you are dealing with dialup. The Client-Server model should be most optimal IMO.

Heh, it seems to depend on the game, I've seen some run at 40fps+ on weak setups and I've seen some run at 1-3fps on monster setups (I'd be specific about the specs but I really don't remember). Something tells me the the code is far from optimized. Well I haven't tried the latest version, hopefully it's improved and perhaps they can make use of newer instruction sets in future versions.

I didn't misread, it seemed he was generically asking about any emulator which has P2P and I figured I might as well say PCSX2 now has it.

PCSX2 and it's plugins have advanced considerably in the past few months and takes advantage of dual-core CPUs, MMX/SSE/SSE2/SSE3/SSSE3 instruction sets and even DirectX 10. I would say the code is more optimised for speed than most emulators we normally use for other simpler systems, and that PS2 emulation is going to need a good system for a couple of years yet.

Well, I do agree with the fact the PCSX2 can't run full speed even on the best PCs. Yeah, I know this was way off topic.

That's quite an improvement over the last time I tried it, it only used up to SSE2. Though their compatibility list is still far from complete.

Perhaps I should have said Direct Connect netplay emulators. One's that don't need to connect to a server for netplay, that is.

It is less optimal to do it with a Peer to Peer connection, mostly because of synchronization.

Desyncing is the most evil thing that can occur in a netplay game.

I think most emulators are directly peer to peer essentially for only 2 players. it's impossible to do this for more than 2 players since you need a server to distribute events to the other players and keep everyone on the same page.

There's p2p Kaillera... Only 2 players, but it makes that 2 player experience 'way' smoother thanks to the joys of not needing any of the central servers.

You can pretty much drag and drop the p2p client onto the old and it'll work. Seems to do well over Kawaks. Dunno about ePSXe, but Supraclient has been offering me no issues on ePSXe while playing Gradius Gaiden. Yet.
