![]() The hardware behind Project Stellar is not even half of the story for today. ![]() On board Project Stellar is a modern and top-of-its-class FPGA that fully implements the memory interface used for the BIOS, as well as the complete LPC interface for I/O and DMA transactions.īut what does all of this mean? By fully implementing the LPC interface, we can give the system access to an additional 8MB of SDRAM plus 16MB of static RAM (all of which is MMU mapped as virtual system memory, CPU cache-able, and usable by the kernel) along with two ARM CPU cores that can be used for off-loading tasks from the Xbox's CPU.Īdditionally, we've added an OLED screen for troubleshooting/error-code readouts, a MicroSD card slot for loading alternative BIOSes (Legacy BIOSes, non-StellarOS), three expansion connections for future add-ons, and USB-C connection for firmware recovery and kernel debugging. Project Stellar takes full advantage of the LPC interface. What's seemed to be lost for the last two decades is the fact that this interface can provide so much more. ![]() Traditional mods for the Original Xbox have used the LPC port to force the system to load an alternative BIOS, operating system, on boot and nothing more. This allowed us to continue on our mission of not only fixing all the problems and issues of the original system, but also adding additional features that have been considered impossible in the past. The hardware was carefully chosen to be as flexible and future-proof. With Project Stellar we set out to build the best possible platform. This is going to be a long one so, grab a snack and let's get to it! Project Stellarĭevelopment of Project Stellar started in 2020, shortly after the release of the XboxHDMI, with the goal of creating the best possible add-on board for the Original Xbox. Using modern software and hardware, we wanted to create something unique that would push the limits what's possible. ![]() Join us as we share with you Project Stellar, StellarOS, XboxHD+ v2, and most importantly the future of the Original Xbox. ![]() Hey everyone! After much anticipation and over two years of development, today is the day we finally get to talk about Project Stellar! ![]()
