Microsoft XDK

PatrickvL: inserted 3944, moved (*) after version number

The official XDK (Xbox Development Kit) was only released to licensed developers. However, it got leaked a couple of times.

CPU

2019-08-09T14:38:11Z

PatrickvL: Added Wikipedia link

The CPU in the Xbox was a custom Pentium III running at 733MHz. The 'custom' part of this was that the Pentium III in the Xbox only had a 128KB L2 cache instead of the usual 256KB. This allowed Microsoft to buy them at a bit of a discount and Intel to shift a few more CPUs{{citation needed}}.

Memory

2019-02-04T15:18:25Z

PatrickvL: corrected address range ends to be inclusive (most where exclusive)

The Xbox has 64MB Memory. This could be expanded to 128MB of memory (and the motherboard has empty spots where these could have been) but no games took advantage of it. The debug Xbox and the Chihiro both contained 128MB Memory.

The memory was shared between the CPU and GPU. On the retail Xbox, the [[Flash ROM]] and [[MCPX ROM]] are also mapped to memory at the top 16 MiB and the top 512 Bytes respectively. On Debug Xboxs and Chihiro, only the Flash is mapped as they don't contain an MCPX ROM.

|The decision was made to create an HLE / LLE Xbox emulation project which is maintained similar to Dolphin or Citra. A key focus was on design simplicity. The project started as a continuation of kvmbox, with devices being copied from the XQEMU source code. The project was called kvmbox-reloaded, while the name was being decided. The HLE portion was never worked on.

Photos of the debug port across every revision (top and bottom) would be useful to show how the PCB traces changed over time. A photo showing the location of the port in relation to other components would be nice, too. Perhaps also photos of rebuilt ports and the pads/vias that must be connected. —[[User:Furon|Furon]] ([[User talk:Furon|talk]])

About this part :

Shouldn't that read :

Memory

2017-11-09T08:52:57Z

PatrickvL: s/get_memory/get_memory_byte

The Xbox has 64MB Memory. This could be expanded to 128MB of memory (and the motherboard has empty spots where these could have been) but no games took advantage of it. The debug Xbox and the Chihiro both contained 128MB Memory.

The memory was shared between the CPU and GPU. On the retail Xbox, the [[Flash ROM]] and [[MCPX ROM]] are also mapped to memory at the top 16 MiB and the top 512 Bytes respectively. On Debug Xboxs and Chihiro, only the Flash is mapped as they don't contain an MCPX ROM.

The Xbox contains an Ethernet module and one RJ45 connector. Additionally, separate modem and wireless accessories were considered when developing the console.

The Xbox has a TCP/IP protocol stack complete with a DNS PPTP, DHCP clients.

Port 3074 UDP/TCP is reserved for Xbox communications.

== Hardware ==

Integrated in the Nvidia Southbridge MCPX chip which is similar to the nForce chips. The Xbox Linux team used the binary drivers from Nvidia.

== Xbox Live ==
Xbox Live is an online multiplayer gaming and digital media delivery service created and operated by Microsoft. It was first made available to the Xbox system in November 2002. ([https://en.wikipedia.org/wiki/Xbox_Live Wikipedia]) Xbox Live support for the original Xbox ended in April 15, 2010.

The Xbox Live architecture consists of authentication servers, matchmaking servers, and game servers.

=== Matchmaking servers ===

=== Game servers ===

=== Authentication servers ===

Authentication and access to Xbox Live services is controlled using the Kerberos protocol with a few proprietary customizations for the Xbox.

Kerberos Authentication Server: macs.xboxlive.com

Please help us fix this mess.
This is an effort to document how the original Microsoft Xbox and the SEGA Chihiro work.
We not only care about technical details about those platforms, but also how to develop homebrew and emulate them.

We are not interested in documenting the Xbox 360, Xbox One or any other console at this point.

This wiki was started by xqemu (Xbox emulator) authors. It will become the place for all remaining Xbox projects to come together.
If you are interested in helping or discussing this, please come chat with us in #xqemu on freenode.
