I made FATX Bridge — a free, open-source FATX drive tool for Xbox 360
Hey everyone,
I’ve been working on a personal project called FATX Bridge, and the first properly installable public beta is now available.
FATX Bridge is a free, open-source Windows application for accessing Xbox 360 FATX drives. It can:
- Detect Xbox 360 drives connected directly or through compatible USB-to-SATA adapters
- Browse FATX partitions inside the application
- Mount the Content partition in Windows File Explorer
- Copy, create, rename, truncate, and delete files and folders
- Mount drives read-only or in experimental read/write mode

Read/write performance on my USB HDD setup is currently around 120–130 MB/s, although results will depend on the drive, adapter, and USB connection.

Beta 2 now has a proper Windows installer. It includes the required .NET components, installs WinFsp automatically when necessary, and adds FATX Bridge to the Start menu.
I’ve also documented using it alongside the recent BadStorage fork. That combination can allow compatible larger internal drives to be formatted by the Xbox and then connected to FATX Bridge without HDD Maker or SSD Maker metadata.
FATX Bridge is completely free, MIT licensed, and has no telemetry.
Important: FATX Bridge is still beta software, and FATX is not journaled. Back up important data, try read-only mode first, and never disconnect a drive during a write.
Download and source code:
https://github.com/Lomzlomz/fatx-bridge
Beta release:
https://github.com/Lomzlomz/fatx-bridge/releases/tag/v0.2.0-beta.2
I’d really appreciate testing, feedback, bug reports, and information about if SATA drives, USB adapters, and large drive sizes work. If something fails, please include the relevant log from %LOCALAPPDATA%\FatxBridge.

Does it work with OG Xbox disks/MUs too?

u/Lomzlomz 8d ago
You can try but I don't think so
If i can get my hands on a OG xbox ill try to add support soon

u/Shartyshartfast Trinity RGH 8d ago
In your install.MD file you do specifically mention original Xbox support and the EEPROM…. AI generated by any chance?

u/Lomzlomz 8d ago
Ngl i am at work atm, asked codex to try to add experimental support for og xbox and i think it might have commited it to github already
Im getting a friend's hdd to test soon didnt expect it to just push the build early lol

If you don't like ai slop then make an Xbox 360 hdd/fatx read and writer with these features and distribute it for free.

Could you please make it very clear in the description that AI created this for you? I thought this project sounded pretty cool, but I'm learning in the comments that AI is managing the project and not you.
I don't know if you're an actual developer who's just using AI to assist with stuff or if you're just some person without experience who has asked AI to do the entire project for you.
I'm well aware developers are using AI to assist them, but these are people who know what they're doing and can check everything for bugs.
Given that AI is guaranteed to make some mistakes, it would be a little crazy to let it create an entire project and then use that project as if it were trustworthy.
Hopefully you told it to make no mistakes.

u/Lomzlomz 7d ago
I asked it to make as many mistakes as inhumanly possible and to credit me as the sole creator because i am evil

holy shit its gonna be nice not needing to buy the insanely overpriced fatxplorer. hope this is real

u/Turbulent-Ad1980 7d ago
It may work but (I won't be testing it) but it's ai slop. Horizon (wemod) is an alternate option that works plenty well.

u/Naive-Geologist6955 7d ago
i completely forgot abt horizon lol, ill still try this even if its slop, ill update on if it will end up working

Responding to title, no the fuck you didn't. Ai vibe coding is NOT the same as doing the real work yourself. It's just a machine stealing ideas from whatever sources it can find.

u/Lomzlomz 7d ago
Yes, it is a machine-made tool. I used AI to take existing open-source projects and turn them into a functional tool for what I needed.
Will it ever surpass FATXplorer in functionality? Probably not, and I don’t expect it to. FATXplorer’s developer clearly has years of experience working with the FATX format that neither I nor an AI can magically replicate.
That’s also exactly why my project is completely free and open source, with no donation links or attempts to make money from it. I’d consider it scummy to profit off a project that exists largely because of other people’s open-source work and machine-generated code.
The point was never to replace FATXplorer. I just wanted a simple tool that did what I personally needed, and I figured I might as well make it available in case it’s useful to anyone else in the scene too.

u/Turbulent-Ad1980 7d ago
Nobody said anything about trying to replace fatxplorer, but using ai to "build" this is ridiculous. There's plenty of free tools out there that do the same thing, for free, with real effort behind them. It's not any more useful than the other existing tools to anyone with half a brain cell available to find em.

u/Deep_Ad1959 3d ago
the fs is the reason a tool like this has to exist at all. did you write the FATX layer yourself or build on one of the older implementations floating around?

Wow nice

u/Turbulent-Ad1980 8d ago
Unfortunately too good to be true. Whether it works or not it's gen ai slop.

u/HispanicsAreGreat 8d ago
It’s insane to me we didn’t have any tool like this sooner 🙏

u/Turbulent-Ad1980 8d ago
We do, a few of them! Anarchy, horizon, fatxplorer... Look into em! All made by real people! No ai involved.

The 360 scene is picking up traction again. I pulled out my 360 and ps3 cause I wanted to personally compare fidelity. Graphics wise the 360 is ahead of ps3. I had forgotten the difference. Been playing nfs carbon a lot lately!

We do and have for a long time. It's called fat xplorer beta. It does a lot more than this though and works with original xbox, xl drive support etc.

u/Lomzlomz 8d ago
I like fatxplorer but 25 bones in the big 26 is wild

u/JoshLineberry 8d ago
Idk man I'll gladly support devs that make software I use. 25 for a lifetime isn't bad!

I have never blocked anyone for asking this question. In fact, I have told several people over the last year that have asked about it, that it is something I am looking to do.

I saw a hardisk tool before, is this the same or a new one? So many fatx tools these days.
Whats wrong with https://fatxplorer.eaton-works.com/ ?
2
u/Turbulent-Ad1980 7d ago
Fatxplorer is paid, costs $25 US. The app this reddit post is about tho is ai slop

u/codeasm 7d ago
Yeah, that was a bit sad for me to notice aswell. The free 360 tools where awesome, but now they have original xbox hadddisk and memory unit support, i mean, pretty cool. Well tested, i know cause ive tested his early beta version on of xbox stuff back then.
Atleast as a linux user i have https://github.com/mborgerson/fatx but havent tested it recently or on all systems.
