Long time modder and lurker, first time poster but I wanted to share a project I have been working on the last couple months.
It is a small PCB which allows you to use Wireless Xbox 360 controllers (via the Xbox 360 USB Wireless Receiver) on an OG Xbox console.
The design is loosely based on another similar project I did for the Nintendo 64 console Please login or register to see this link. Following the release of this board another forum user sent me an email asking if this device could be adapted for the OG Xbox, and funnily enough that was the next thing I was going to attempt!
I wanted to support the following features atleast:
Up to four players with rumble support.
100% USB Bus Powered so no external power supply needed.
Fast bootup time, so it's up and running in time for the OG Xbox.
Low input lag. As always, this is a hard thing to measure, however I can say that an OG Xbox controller is polled by the console every 4ms or so. My software gathers all the Xbox 360 wireless controller data, collates it and generates all the HID reports every 4 ms aswell. It's possible an input may miss this 4ms window, so would happen in the next 4ms window.
As you probably know, an OG Xbox controller is basically a USB HID device, however it has some custom requests and other slight differences, meaning that it doesn't work on a Windows machine without a custom driver, and conversely a generic HID controller will not work in an OG Xbox so there was some work in getting a reliable and compatible solution working.
To support four controllers, it is necessary to have 4x Full USB device controllers. However I imagine most people would rarely play with 4 people at once so my design is modular meaning you can support anywhere from one up to 4 players as required to keep cost down.
This is a link to the github repo with what I came up with Please login or register to see this link.
I'm interested in converting the original wired "S" controller into a wireless controller using the guts of an off brand wireless controller like a Logitech. To anyone's knowledge has this been done before or at least something similar?
