Modxo (pronounced "modsho") is a firmware that emulates an LPC bus, converting the Raspberry Pi Pico into an Original Xbox modchip capable of running a modified BIOS.
Build Circuit
Note: D0 is only needed by versions different from 1.6 and the LFrame pin connection is only needed by version 1.6. In addition, LPC rebuild is required.
Requirements
- Working LPC Port
- Original Raspberry Pi Pico or RP2040-Zero (some clone boards are not compatible unless specified otherwise)
- x4 100 Ohm resistors (tested with 1/4 W resistors)
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.
