Game Leaks are a hot topic right now. Perhaps no story is more crazy than the Xbox 360 and its PartnerNet service. In this episode we take a look at the story of how Microsoft were unable to control game leaks on the Xbox 360 because of critical security flaws within the PartnerNet service - the Developer version of Xbox Live , and how thousands of unauthorized users were able to access PartnerNet and download and leak pre-release beta games months before official release.

Are you ready for some OG Xbox emulators?

Xbox and Windows NT 3.5 source code leaks online

The source code includes parts of the original Xbox operating system

Microsoft’s original Xbox console source code has leaked online, alongside code for a version of Windows NT 3.5. The Xbox source code includes the kernel for the operating system on the original console, a custom version of Windows 2000. We can confirm the leaked Xbox OS is genuine, and appeared online earlier this month. “We’re aware of these reports and are investigating,” a Microsoft spokesperson said in a statement to The Verge.

While the Xbox OS leak includes some build environments, the Xbox Development Kit, emulators used for testing, and internal documents, we understand this kernel and source code has been passed around privately among enthusiasts previously. That means it’s unlikely to help further homebrew and emulator efforts for original Xbox games.

A number of emulators exist for the Xbox, including CXBX, XQEMU, and CXBX Reloaded, but most have struggled to emulate the original Xbox OS and kernel. Microsoft developed the first Xbox with x86 hardware in mind, but the Xbox kernel was based on a custom and stripped down version of Windows 2000 with DirectX 8 support.

Unofficial emulators have tried to replicate this kernel for years, but so far only around 40 games have limited emulation support compared to the 900 games available for the original Xbox. Microsoft has its own proprietary emulation for Xbox and Xbox 360 games, but it’s only currently available on Xbox One consoles and not on Windows PCs.

Alongside the Xbox leak, source code for a near-final version of Windows NT 3.5 has also appeared online. The source code includes all the necessary build tools, and should allow enthusiasts to dig into the old operating system. As Windows NT 3.5 support ended in December 2001, the operating system is only used in a small number of systems worldwide so a source code leak isn’t a significant security issue.

Microsoft has largely protected its proprietary Windows and Xbox source code over the years. Partial Windows 2000 and NT 4 source code leaked back in 2004, and even some Windows 10 source code was posted online in 2017. We asked Microsoft to comment on the Windows NT 3.5 source code leak, but the company says it has nothing to share about this particular incident.

Reading the article, it sounds like this leak won’t help at all with emulators.

It will help if someone decides to reverse engine the source code. It will be an illegal emulator, but it should work better than the legal ones.

Xbox Series X can add HDR and 120fps support to older games

Some games will double in framerates

Microsoft is planning to automatically add HDR support to games played on its upcoming Xbox Series X console. While existing games will automatically play better on the Xbox Series X, Microsoft is also doing some work to add HDR support and even improve some games from a 30fps locked framerate to 60fps, or 60fps to 120fps.

“In partnership with the Xbox Advanced Technology Group, Xbox Series X delivers a new, innovative HDR reconstruction technique which enables the platform to automatically add HDR support to games,” explains Jason Ronald, a partner director of program management for the Xbox platform team. “As this technique is handled by the platform itself, it allows us to enable HDR with zero impact to the game’s performance and we can also apply it to Xbox 360 and original Xbox titles developed almost 20 years ago, well before the existence of HDR.”

Ronald doesn’t explain exactly how Microsoft is adding HDR to existing games, but the company has, in the past, added HDR support to older games like Mirror’s Edge on the Xbox One X. Microsoft’s new “HDR reconstruction technique” is applied at the platform level so it requires no work from developers. Microsoft may simply be upscaling and processing games in HDR, similar to how Apple forced all non-4K content into 4K HDR for its Apple TV 4K.

Microsoft is also planning to improve and preserve some older games that run on the Xbox Series X by upping framerates. “The compatibility team has invented brand new techniques that enable even more titles to run at higher resolutions and image quality while still respecting the artistic intent and vision of the original creators,” says Ronald. “We are also creating whole new classes of innovations including the ability to double the frame rate of a select set of titles from 30fps to 60fps or 60fps to 120fps.”

Ronald doesn’t reveal exactly how Microsoft is achieving this, and simply promises to share more closer to launch. It’s likely that Microsoft will unlock its Xbox emulator further on the Series X, thanks to the increased power in the CPU and GPU architectures. That alone could improve framerates in certain games, allowing some to remove caps and go beyond CPU or GPU limitations that may have been holding titles back previously.

Alongside these game improvements, Microsoft is also revealing that its Quick Resume feature for the Xbox Series X can be enabled on existing backward compatible titles. Quick Resume is a feature that lets you quickly switch between multiple games, resuming where you left.

All of these improvements are part of Microsoft’s continued backward compatibility work that allows original Xbox, Xbox 360, and Xbox One games to run on the Xbox Series X. Microsoft says games will run without needing a boost mode and there’s no downclocking involved. Microsoft is now planning to show off some of its plans for first-party next-gen games in July, and Ronald teases “our 15 Xbox Game Studios teams are ha
