If you have been following the #OGxbox scene, you would have probably heard about ModXo, a #raspberrypi based modchip. ModXo has been covered by Macho Nacho & others.

I am now offering my own build of ModXo through my website, using @modzvilleusa.bsky.social design. Check it out at topvint.co.uk!

Did you know that you can hard mod an #OGxbox with a #RasperryPi? It is called a #ModXO chip, and is now part of Team Resurgent, one of the most prolific groups of the open source OG Xbox scene.

Learn more about ModXO in the Github website and the thread below 👇

You can also buy one that has already been made. I do sell the TopVint ModXo mochip in my shop, which I created using @modzvilleusa.bsky.social PCB design and I assemble myself.

Next up the Topvint ModXo installation. The previous LPC rebuild had a couple of missing pins in the port, which I had to put back an resolder. The Topvint ModXo modchips come with PrometheOS and the latest Cerbios in the first bank.

The shields were sanded and repainted, and a 500GB SSD installed alongside a Startech SATA2IDE adapter and an ASUS UDMA ribbon cable. A ModXo modchip with PrometheOS was also installed, Cerbios 3.1 in bank 1, and the UIX Lite dashboard 😊

2nd thing built today: Modxo RPi Pico based OG Xbox Modchip! 👍

Well, I didn't design these #OGxbox ModXO PCBs (@modzvilleusa.bsky.social did), but I ordered and assembled them, which is an achievement for me 😅. They work great, too

yooo modxo carrier board spotted
May 9, 2025 at 11:57 PM
Currently building my own #modxo modchip now that I received my PCB design from the fab. I wanted most barebone carrier board as possible. Such a fun experience from start to finish.

anyway it's on github if you want to get one from pcbway or jlpcb or whatever.

Although my XBOX is soft modded, I really like the sound of the modchip on offer.

But the best feature of the ModXO is that it is based on the well known RP2040 microcontroller platform, and the firmware is open sourced, making it pretty future proof! For example, you can run the #PrometheOS BIOS, which starts a web server for futher customisation, all running in your modchip!

I need to get a low-end PVM, an OG Xbox, and a ModXO one of these days
May 17, 2026 at 1:16 AM
How can you get a #ModXO modchip? Well, you can make one yourself! The Team Resurgent website includes instructions on how to do this, as well as how to flash a Raspberry Pi with the current firmware.

open source lpc device emulator for the original xbox called Modxo (pronounced modsho, linked in embed), running PrometheOS which lets me directly format and ftp files into a new drive, as well as being able to run the bios of most modchips, attached through an adaptor by @modzvilleusa.bsky.social

yep! glad it only took a few hours for the repair work and can move this one along, got a 9 more customer boxes stacked in a pile near my bench ready for work. OG xbox up next for recap, cleaning, modxo modchip, SSD, etc

Instalación del modxo hecho con éxito (me había liado con un cable pero ya esta corregido).

Después de cambiar los condensadores a la consola no me daba imagen y con el mod ya vuelve a dar.

El rp2040 esta así para hacer una prueba rápida. Pienso ponerlo bonito con adaptador y quitar los cables.
