What's the point in having a link feature if it's only on the same PC? It's not like that's a viable way to have multiplayer.

is there a gba emulator that can link through the internet, or even just a LAN? I don't know any, but if you like, you can download the source of VBALink and add it there.

No, no and no he can't because it's impossible.

well maybe it isn't impossible for multiplayer mode (would just be sloooooow) but for the other modes - yeah

If someone knows anything about network programming (or where I can find something about it), I'll be glad to hear

No, it is impossible. I saw a thread on this on the BoycottAdvance forums. Gollum (the author of BoycottAdvance) came in to say that it was impossible. I debated it with him for a while to be sure, and came out convinced. The GBA link cable has a 2 megabit transfer rate (difficult to get over the internet, not so difficult on a LAN) and near zero latency (impossible to get over the internet and extremely 'tricky' even on a LAN).

I don't just mean those are the requirements for having a good game of Mario Kart: Super Circuit, you'll need the same to even trade some Pokémon.

Well, I'm speaking about multiplayer mode - the highest speed is 115200 bps

Try to look at the code, you'll see latency isn't a problem - it'll just slow down the emu

Believe me, I know that. When trading pokemon, the gbas communicate at about 1200 Hz (1200 18bit transfers from each gba).

E-mail Gollum then. Tell him he's wrong, that latency isn't actually a problem, and that you know better than him on this one. You'll find his e-mail address here (http://www.bannister.org/cgi-bin/ultimatebb.cgi?ubb=get_profile;u=00001878).

If you didn't get it by now, I wrote the link in VBALink and it seems to me that I know how it works and it works WELL.

Yeah. but not with linking to other PCs, which is practically impossible with today's networking hardware. That's what Lillymon is talking about. <img src=smilies/banghead.gif>

I don't say it would be fast enough to even trade pokemon through internet but I think LANs are able to transfer about 115200 bits per sec, which is the MAXIMUM in multiplayer mode

Then actually write the goddamn code to do so instead of getting in a dick-measuring contest.

I'd like to do that but 1) I don't have a local network to test it on (yet) and 2) I don't know anything about network programming (yet)

But I'm gonna work on it.

You're the one who knows so damn much about the way the GBAs link together, you tell us.

If you'd been paying attention, my actual words were "extremely 'tricky'" for LAN play. You can obviously get a lot less latency on LAN than you could on the internet due to the much shorter length of cable.

Hey, do you have a full list of changes for the new version? I see a regular v1.72L version and is there ALSO a LAN version? Or is that just part of the new version. Sorry, I'm just a bit confused as to what is what here. I want to know the facts before I report anything! :o

Oh Jesus HS Christ, people. This guy's writing good code, has been nothing but congenial, and all you can do is bitch him out. It's a wonder there's anybody left programming in this community.

There aren't any other significant changes, except that I hope Doom and Mario Kart now run properly.
The version before this was 1.7.2, so the L stands for LAN (not for link, as you probably thought).

Lillymon is (as she says herself) a bitch and will never be satisfied with VBALink.

This isn't the first time I've done this. Remember phamicom? The FCE Ultra derivitive that never went anywhere? I still wonder if I caused that...

Glad you know that. I'll probably never use it anyway, since I prefer single player and would put speed infinitely above link emulation for what I seek in a GBA emulator.

BTW, bad feelings don't easily dissipate with me. Expect the Sega rewrite to be done and in MAME before I forget this incident.

Yeah...although everyone is entitled to their opinion, I agree. I think anything like this is quite a cool thing indeed.

Yes, VBA is also a bit slow IMO, but I didn't want to write a whole new emulator (when the best was opensource).

I don't have any bad feelings about you. I just don't care.

Just to let you know, some people already used VBALink over the internet and they had no problems (besides low speed)

You know, there's a reason I'm not going to forget this until the Sega rewrite is done in MAME. Because that's probably the amount of time it'll take you to stop bumping this thread and refreshing my bad feelings.

Let's make a deal. Start a new thread, and I'll go destroy some other emulator. Sound good to you?

Agreed. Snotty comments are unnecessary. perhaps moreso dircted towards people that are developing emu code and the like. We should be supportive or zip, zip, zip it.
