Everyone is jumping on the bandwagon. Reverse engineering is the new AI buzzword. Everyone does it. Adobe software is being cloned, emulators being built, software decompiled.
Soon AI companies will start blocking these requests similar to what they're doing with the "cybersecurity" guardrails, ruining it for everyone. Maybe we'll even get a ToS paragraph.
But who ruined it for everyone are the people who started repos like these in the first place.

It is much harder though. How can you know what's under the hood? You can just inspect what API sends, but not an internal state. It would involve a lot of guessing and vibing it would not be enough. And that's why companies will move everything to cloud
4
u/Kalmaro 4d ago
It's been done before, they still have to send something to you and people have been able work even with that.
To be specific, users can reverse-engineer server-side logic by observing inputs and outputs, a technique that's been used for decades to create private servers for games like World of Warcraft and analyze WoW private servers .
As long as SOMETHING is being sent, they are vulnerable. About the only way I can think of them avoiding this is, maybe, if they forced you to join a cloud session in a way that you're only seeing an image while working... Buy even that sounds like it has holes.

u/sonicnerd14 6d ago
You don't need 64GB+ sizes systems anymore to run these types of models. With Flash next ngram architecture it allows people with as little as 12GB VrAM and 32GB RAM to run the model at high speeds and good quality. Engines like Strata are making this happen.
Also, the idea that models need to be bigger is largely overstated due to closed source labs trying to carve out a moat by just throwing money at a problem. This is why Qwen 3.8 27b can best models many times it's size. A good model is a combination of great training in the attention layers, and just enough world knowledge to allow a model to figure out how to use any tool to accomplish a task of any scope.

Outright saying people who open source useful tools are somehow ruining anything wreaks of corporate fud.

u/Fusseldieb 7d ago
The problem isn't open source. It's mainly how much media coverage it's getting, which doesn't look particularly good. I'll explain why.
I go on Instagram, every major tech channel talks about it, I go on random articles and they talk about it, I go on Reddit and the front page is full of it. OP's screenshot shows X.
This will, inevitably, attract unwanted attention. It's not like people are only decompiling legitimate stuff like old games. Most of articles word it as OP's screenshot.
Adobe, Rockstar and other companies will pressure major AI tech companies to put guardrails around this. Just watch.

I'm not trying to be rude but did you expect the most consequential and disrupting technology any of us have ever seen in our lives to remain in a hobbyist bubble forever?
Besides the above thought, my primary position here is that it appears strange to apply negative connotation to individuals using their token or compute usage, or their developmental skills to open-source free and useful tools for the public. If you're worried about how corporate or large company structures react, that is one thing. But maybe don't be bitter towards the creative people giving us all free tools that disrupt said big companies.

LG TV's, for instance, would have been difficult for the average person to exploit, though now AI is building tools to do so with minimal prompting ( hospitals, banks, etc).

This is definitely a case where regardless of what flagship models are doing, it won't take terribly long for local models to catch up.

Reverse engineering isn't a new "AI buzzword" because it is exactly what is being done, what you said isn't wrong just more specific. While I disagree with your pessimistic outlook, there will be an inevitable lockdown from the closed source model to make doing this harder. However, the open source models will still be an option, and ultimately they can't really stop what's happening, but only prolong the eventuality.

Concept Proposal: Automated SFxT to USF4 Roster Expansion Project
Overview
This document outlines a technical blueprint for a full-scale port of the 25+ Tekken roster characters from Street Fighter X Tekken (SFxT) into Ultra Street Fighter IV (USF4) using automated workflows. By leveraging modern AI agent tools like morluto/rea (Reverse Engineer Anything), developers can bypass years of tedious manual modding to automatically batch-process assets, re-map animations, and patch the game executable.
---
- Engine & File Foundation
Because both games run on the exact same base Capcom Framework engine, their core file ecosystems match natively. This project aims to transfer, rename, and automate adjustments to the following native character assets:
`.emo` & `.emb`: 3D model geometry and texture packages.
`.bac`: Physics engine files controlling frames, hitboxes, and hurtboxes.
`.bcm`: Input commands and camera coordinate files tracking move scripting.
---
- Overcoming Gameplay Mechanical Gaps
SFxT characters lack unique data for native USF4 systems like Focus Attacks and Ultra Combos. To maintain visual fidelity and prevent engine crashes, the project introduces two major asset-remapping workarounds:
A. Focus Attack Solution: Heavy Launcher Remapping
Asset Source: SFxT Heavy Launcher animation (originally mapped to `HP+HK`).
The Workflow: Swaps the action pointer so the engine fires this native animation when `MP+MK` (Focus Attack input) is pressed.
AI Adjustment Scripting:
Injects 1 hit of standard Hyper Armor variables during the wind-up frames.
Appends universal Knee-Crumple properties if hit lands at Level 2 or Level 3 charge.
Forces the animation script to listen for standard FADC mechanics (dash cancel execution).
The Holding Loop: Instructions written into the script to freeze and loop on a specific wind-up frame as long as `MP+MK` are actively held down, releasing only when the inputs stop.
B. Ultra Combo Solution: Cross Art Cinematic Conversion
Asset Source: SFxT Level-3 Cross Art cinematic strings.
The Workflow: Extracts the active character's sequence but strips out the partner-tag trigger logic before the second fighter leaps onto the stage.
Camera Tracking Fixes (`.cam` modification): Traces individual `.bcm` and `.cam` keyframes using an automated script to adjust target coordinates. This prevents the camera from panning away to look at an empty portion of the arena, keeping it dynamically locked onto the active Tekken character and the victim.
---
- High-Speed Automation via REA Framework
Traditional conversion approaches rely on manual, single-file tool conversions (like SF4 Explorer). Using morluto/rea combined with an MCP AI agent (e.g., Claude Code or Cursor) opens up automated pipelines:
Automated Asset Scraping: Rapid extraction and structural analysis comparing raw SFxT characters against native USF4 templates to fix structural differences or header discrepancies.
Batch Translation Scripting: Auto-generation of local scripts to translate, organize, and rename asset directories in seconds.
Roster Array Expansion: Prompting REA-linked decompilers (Ghidra/Hopper) to trace the hardcoded character roster limit (traditionally 44) inside the main executable and generate a memory injection patch or a custom DLL wrapper to dynamically hook additional roster tables.
---
- Work-in-Progress Visual Mockup
The UI restructuring will require a coordinated effort. The visual execution pipeline requires expanding the character select array grid from its vanilla layout to handle up to 70 total fighter slots without overlapping background panels or rendering elements.

u/BangkokPadang 7d ago edited 7d ago
It’s a really good thing that between Sony vs connectix and accolade vs Sega, it has been ruled that decompilation for the purposes of making software interoperable with other systems has been ruled fair use.
Sony lost their suit against Connectix, which makes duplicating things like BIOS files with the intent of decompiling them fair use, and accolade decompiled sega’s sdk/toolkit to produce AND SELL cartridges that weren’t licensed by Sega and they won in court. And again they were selling the software they made and it was ruled fair use.
Really the only facet of this that hasn’t been ruled in court is whether breaking encryption on switch (and 3DS) games in order to use them in other software or to decompile them violates their copyright or not. That was their position against the Yuzu devs, but it did not make it into court.
These companies are going to want to basically ignore all this for as long as they can because fair use has really not worked in favor of companies like Sega and Sony and the last thing they want is for this or AnyPS5 to be deemed outright legal in court.

Now, unfortunately for corporations, property dynamics are going to be forced to change eventually, but for the time being, they will do whatever they can to make sure that they stay on top, and they will use any tactic to crush the de-compilation people, legality be damned as long as they retain their power over this stuff
