This is a copy of portions of my thread over at BitBuilt https://bitbuilt.net/forums/index.php?threads/xboxdvi.3304/ As some of you may know, the original xbox is really lacking in video output modes for the modern era. It is only capable of analog video out, and doesn't even support VGA through that. Early versions of the xbox use a CX25871 as the video encoder, which can take a variety of digital inputs and in turn outputs analog video. https://html.alldatasheet.com/html-pdf/153349/CONEXANT/CX25871/384/1/CX25871.html My suspicion is that the xbox uses the highest quality of these potential inputs, RGB24. If that turns out to be the case, I should be able to use the Texas Instruments TFP410 to turn these signals into DVI https://www.ti.com/product/TFP410 End goal is to have a board with a BOM of under $20 that I can then install in my absurd stack of xboxen. The catch: This is my first circuit design project and my first PCB design project, so I'm starting out way over my head. Wish me luck, I guess. -------------------------------------------------- I've since found that my initial assumptions were incorrect, and I've made it to my second prototype. It still has issues, but I'll find out soon enough if I'm on the right track. --------------------------------------------------

I was going to update the post, but apparently we're only allowed to edit for a few minutes. I've gotten the whole circuit laid out now. We're once again at the "Sleep on it" stage where I take a nap and then decide how I feel before ordering anything. 20.5mm*56.5mm, or slightly smaller than the fan cutout in the motherboard.

If anyone has a Hyperkin Duke controller, I think ive got it working in the latest firmware update. If anyone is bored and wants to try it out, the firmware is here: https://github.com/Ryzee119/ogx360/releases/tag/1.4 You will likely only need to update the 'master' module on your ogx360
