System link / 4-Player Coop For Halo 1

adolif · Post by **adolif** » Thu Nov 06, 2008 3:14 am

Well, I just did this to see if it works, here you go, it works, actually, system link is untested, so please somebody test it. Split screen has been tested, and fully functions.

It supports proper respawning of dead players too.

How to Use:

-Patch the xbe
-Patch the mainmenu
-Place all SP maps with unmodded headers into maps folder.
-Read The info Below
-Play Coop

Patches are in ppf format.

battle creek ----> pillar of autumn
the map slot to the right of battle creek -----> halo
the next slot -------> truth and reconciliation

etc

There is also no gametype select screen to allow a SP globals tag to load properly and to allow you to spawn.

Enjoy!

I'll get some screenshots after school.

If anybody wants to play xbc or xlink with me, also let me know

.

Also, my capture card SUX.

Please don't mind horrible screenshots.

Words cannot describe the amount of awesome contained in this mod. Not only does system link work, but you don't even need the other Xbox to be modded. I just played a co-op with people on XBC (who were needless to say very confused).

The only problem is that in system-link if one of players gets loaded the game will go out of sync. So both players need to go through at the exact same time for it to work.

So, so amazing.

!!!!!!!!!!!!!

This needs front page now.

You actually like it? That surprises me, as it was only an experiment. XD

Time for me to get screenys.

Oh my. Interesting. I thought about doing this for like the past year. Just never had time. Great job!

I'm hosting a game on XBC if people want to play. Just hit me up with a message my tag is Garzahd. So far I haven't been able to complete a level without the sync screwing up. I've been experiment trying to avoid loading the other player.

You have to be really careful, it de-syncs very readily skipping cut-scenes will always do it, dieing will sometimes, it kind of adds a whole new element of danger to the game.

I'll upload some better screenshots lol

7 player co-op time lmao.

Try xbc'ing just two people and see if any of those same symptoms of de-syncing happen again. That may give a small amount of insight as to what happened.

I just might pull out Halo 1 again. I've always wanted to do 4 player co-op!

That's what I had been doing, I just linked up 7 people so I could get a cool screenshot. It can't really handle 7 at all, there aren't enough spawn points for everyone to start the game all at once and you get de-sycronized right away. But the biped(s) will hang around (and respawn) even though there is nobody playing them.

It will sometimes de-sync randomly, but most of the problems are caused when one of the players is teleported due to a loading point.

I gotta go to class for now, but I'll be back on XBC around 5:30pm-ish (EST) if people want to play.

Outstanding mb...?
I can't wait to try this. Good work!
EDIT: Sweet. It works like a charm. I love this!

Thats so awesome. When you die, do you just respawn at the start of the level or actually by the group of people?

By a group of people.

I'm just curious, how exactly did you do this...?

nintendo9713 · Post by **nintendo9713** » Thu Nov 13, 2008 8:51 am

So are people still trying to test this for system link without syncing issues? I would love to have about 13 of my friends come over and we completely demolish this campaign. So does it go out of sync at every loading point and is there a fix to it?

I had to trick the xbe into loading the SP maps into the MP map slots, and then i noticed the gametypes require MP globals tags, so I then removed the gametypes select screen and it allows you to load a SP map in MP mode.

And in case you need to know my hex editing utility, I use Cygnus hex editor free edition.

Let me guess. You found in the .xbe where a multiplayer map is loaded and changed that to the name of the single player map? And just completely cut out the gametypes select? That sounds right?

Like I said, it was an experiment, I wasn't expecting a single download. 0_o I mostly posted this not so people could say "awesome mod" but so people could know that it works and functions to do it with that method. Long story short, you're right on the money.

kibito87 · Post by **kibito87** » Thu Nov 13, 2008 3:24 pm

Well, i'm just wondering for use in further experimentation. Only because I may have ways and methods that further the ability for this to be played.

Well, I tried to change the ui to make co-op load with 4 people instead of 2, but halo only loaded the first two profiles when the game started.
Hmm...
Any way of tricking the xbe into loading more than two people?

You have to load it in split screen mode, like I did. You remove the gametype select screen by ui widget swapping, and then you hex-edit the xbe to load SP maps in MP map slots. Maybe I will release a tut?
