Hi everyone
Development and testing continues on seamless co-op for Dark Souls II. In this post I'll discuss what I've been working on this past week.
In a previous post I briefly detailed the work and functionality of respawning players in the mod.
In other seamless co-op mods, connected players remains pe...

Hi everyone
I wanted to give an update that leads on from the post previously when I was talking about the challenges of implementing game-wide enemy AI synchronisation between game clients, something that is uniquely challenging in Dark Souls II
Enemy AI is implemented (in my opinion) poorly in Dark Souls II.

Hi everyone
I am back home and have started back with seamless co-op development. In this post I'll describe some of the results of the playtest I did this afternoon. Mainly focusing on the bugs and issues encountered along the way.
Overall: It's working "OK" in a sense that it's playable with some issues I can fix quickly and some I can't - One of which is detailed belo...

Hi everyone
Following the previous post I made a few days ago, I wanted to give some information on some of the behind-the-scenes goings on with the mod development. The post will go a bit more in-depth to the reverse engineering aspect of two elements of the mod I've been working on today.

I hope everyone is doing well!
I've been rather focused the past week on pushing past some of the obstacles I've encountered during DS2 seamless development. In this post I'll go over the progress I've made on these issues and where the mod is at right now.
It has been longer than I'd like since the last post but I've been distracted by mod development. I'm still here!
Hi everyone!
I finished my exam on Wednesday this week. So now I am available to dedicate more time to the Dark Souls 2 seamless co-op project.
In this post I'm just going to discuss a few more development points in the mod.
I've spent the past few hours today working bonfires into seamless co-op.
As I expected, whereas enabling bonfire ...

Hi everyone!
I hope you're well - The last update post for this project was all the way back in May of this year.
To clarify, I have been very busy with my personal life since July and as a consequence all of the mod development for my projects have been slow and delayed. However I hope by reading today's update post it will seem a little closer to being playable.
Hi,
I hope everyone is going well. I just wanted to make a quick post since it has been a few weeks since my last one and wanted to give an overview on what I've been working on.
There is a fix for the Lautrec bug which ...

Hi everyone,
I've been taking a short break to work on a side-project -- Elden Ring Nightreign Seamless Co-op.
As I'm aware that FromSoftware will implement official 2-player game session support, I've shifted the mod more toward being a purely multiphantom (4+ player) mod. Likely stopping at 12 players, and then allowing other modders to create their own game-modes which could make...

Hi everyone
I've been doing some more work on Elden Ring: Nightreign. As it's likely FromSoftware will eventually add duos into the vanilla game (hopefully) then seamless co-op will likely have to be repurposed slightly.
Player cap removal
I have removed the player cap for the game. This will hopefully allow for more fun game modes in the future (with increasi...

Hi everyone,
Elden Ring: Nightreign was released today. I played a little bit this evening and managed to get together a functional multiplayer system without connecting to the matchmaking servers (and therefore not needing to run EAC).
The benefit to this of course is you can opt to play with just 2 players (instead of matchmaking with a random) and also being able to play mods whe...

Hiya,
Just to reassure everyone that I am hard at work with the seamless co-op mod for Dark Souls 2.
As I've mentioned before, an overwhleming amount of the work has been reverse engineering stuff (and trawling through lots of x86 assembly) to understand how the game works. Once I had familiarised myself with it, getting sessions to work without the matchmaking server being involved...

I wanted to post another update on the status of the Seamless Co-op mod for Dark Souls: Remastered.
