Modxo (se pronuncia "modsho") es un firmware que permite emular el bus LPC, conviertiendo la Raspberry Pi Pico en un modchip para el Xbox Original capaz de correr una BIOS modificada.

Construcción del circuito

Diagrama de conexión para el circuito del Modxo

Nota: D0 solo se requiere para las versiones que no sean la 1.6. La conexion del pin LFrame solo se requiere para la version 1.6. Además que la versión 1.6 requiere la reconstrucción del puerto LPC.

Requerimientos

• Un puerto LPC funcional
• Una Raspberry Pi Pico Official or RP2040-Zero (algunas tarjetas no son compatibles)
• 4 Resistencias de 100 Ohm (se ha probado con resistencias de 1/4 W)

Installation Steps

• Connect your Raspberry Pi Pico to a PC while holding down the BOOTSEL button, and a new drive will appear.
• Copy the latest "Modxo.uf2" firmware onto the root of the mounted drive.
• Reconnect the Raspberry Pi Pico while holding BOOTSEL to bring up the previous drive.
• Copy your BIOS UF2 file into the drive
• Copy over your converted BIOS UF2 file onto the drive.

Packing BIOS

• Go to https://shalxmva.github.io/modxo/
• Drag-and-drop your BIOS file. (This will work with any compatible BIOS image, including stock.)
• The UF2 file with BIOS image will be downloaded.

Note: Various 'flavors' of this packer are available on the repo, in Python, and GoLang, to be ran locally.

Adapter Boards

Note: Current adapter boards are for revisions made before to July 1st, 2024. This is an ongoing in-development project, and new pinouts will be added to allow for further functionality.
