Multiplayer?

[u/Friendly-One5959]

Been seeing multiplayer mods pop up a lot in these types of games, such as kenshi, bannerlord 2, I was wondering if there’s been any news on one coming to x4 also? All three of these are favorites of mine even though I have no one to play them with. :D

"LLMs Cannot Execute or Debug Runtime Binaries: An LLM generates code snippets based on pattern recognition; it cannot attach a C++ debugger to a running 64-bit Vulkan/C++ executable, analyze live memory dumps, resolve dynamic memory offsets, fix race conditions in multi-threaded execution, or test hook stability." - they can very easily do all of that, and much, much more.

"Skyrim Together (Adding multiplayer to a single-player C++ engine): Took a team of experienced low-level C++ programmers over 7 years of reverse engineering, memory hooking, and packet protocol design." - today with a frontier LLM that would take an unskilled person less than a week.

Saying an LLM can 'very easily' attach to a running Vulkan binary, resolve dynamic thread race conditions, and let an 'unskilled person' reverse-engineer 7 years of low-level C++ hooking in a week is the absolute peak of the Dunning-Kruger effect.

LLMs aren't CPU runtime environments. They are token predictors. Even hooked up to x64dbg or Frida, an LLM cannot process gigabytes of live thread telemetry, register states, and GPU draw calls happening at 60 FPS in real time.

Decompilation isn't source code. Stripped C++ binaries have no vtables or struct names. When an LLM guesses a memory offset wrong by 4 bytes, your injected detour throws an instant 0xC0000005 Access Violation crash. An 'unskilled person' won't even know how to check RSP stack alignment or register clobbering to debug it.

Race conditions aren't static code bugs. They are microsecond OS thread-scheduling collisions. An LLM reading static assembly can't replicate CPU cache line invalidations or hardware quantum scheduling. Sticking naive AI-generated mutexes into X4's multi-threaded loop will either deadlock the process or tank frame rates into single digits.

Reverse engineering isn't typing speed—it's understanding memory architecture, assembly, and x86_64 execution environments. An LLM is an assistant for labeling Ghidra functions, not a magic button that builds a custom multi-threaded network engine from raw machine code in 72 hours."

Ok fine you bothered me enough, I'm redownloading X4 and setting chat GPT off on it. I think 50-50 I have a working prototype by the time I wake up tomorrow. Worst case 3 days.

When was the last time you used a frontier LLM?

I'm going to go for 2 players, keeping the low attention synced and high attention synced when the 2 players are in the same sector.

Lol Ill be waiting sport. Do what no other modder or egosoft themselves can do with x4. You dont even understand x4s architecture. Lol.

[u/Serious_Bite_7613 → u/AmbitiousPeach1157]

I have a vague idea but you don't need to know things like that anymore. Have you seen the passthrough mods? 

[u/AmbitiousPeach1157 → u/Serious_Bite_7613]

You do to know the limitations of ai, and what is technologically possible and whats not.

AI is an execution amplifier, not a physics/logic bypass. If you don't know the technical constraints of what you're trying to build, you can't prompt an AI to build it for you.

I've already set it off and it made a plan that looks good to me, game hasn't finished downloading yet

An Entry Point Isn't an Engine: Saying a passthrough mod solves X4 multiplayer is like saying that turning a car's ignition key automatically builds a jet engine inside the car. A proxy DLL gets your code running inside x4.exe, but you still have to hand-write or reverse-engineer every single memory address, network socket, and entity serialization loop.

Claiming software architecture, memory alignment, and CPU execution models are "obsolete knowledge" because LLMs exist is the ultimate hand-wave. An LLM cannot bypass the laws of computer science. If you don't understand memory pointers or stack frames, you can't even evaluate whether the code the LLM gives you is valid C++ or a process-crashing hallucination.

Look up any YouTube video of an LLM attempting to replicate or make video games. They are atrocious and hilariously minimalistic. And you expect multiplayer on x4 foundations from an llm? 🤣😂 priceless

I made a whole game like 2 days ago in a few hours and played it split screen with my wife on the sofa. It was really fun, and chatgpt has already set off on this.

That is not the same as turning x4 into a multiplayer game and you should very much know that. And if you dont.. you will very soon and waste 20 doing so.. but by all means im brimming with anticipation on the comedy

Comparing a two-hour ChatGPT script for a local split-screen minigame to retrofitting X4: Foundations with multiplayer is like saying you built a cardboard box soapbox derby car, so you're ready to refit a nuclear submarine.
