When Microsoft ruled out backward compatibility during the Xbox One’s launch in 2013, it just seemed like par for the course. 

At the time, consumers were generally expected to start their gaming collection from scratch whenever a new console came out and hold on to the necessary hardware if they ever wanted to replay older games. 

There was also a common consensus in the industry that people probably didn’t want to play last-gen titles, something which Microsoft has since categorically disproved. 

In an interview with TRG, we spoke with Xbox’s director of program management Jason Ronald about the team’s backward compatibility journey, the challenges they faced along the way, and the importance of game preservation in the future.

In 2015, Microsoft rocked E3 with a seismic announcement: backward compatibility was coming to Xbox One. Fans could look forward to playing Xbox 360 and original Xbox games again, and even use the original disk, play over Xbox Live, and access their old save files if they’d been uploaded to the cloud. 

The raucous cheers that erupted throughout the Microsoft Theater on that day ultimately solidified one thing: people still wanted to play these older games that were cherished by the gaming community.

Jason Ronald, director of program management at Xbox, still remembers those cheers today, and how they helped invigorate the team behind Microsoft’s ambitious project.

“When we announced it – it's probably the biggest reaction I've ever seen at one of our press conferences,” Ronald says with a smile. 

“It just really gave confidence to the team. Like, we're on the right path. We're listening to the fans, we're listening to the community, and they love what we're doing. And that's really been what's powered the entire backward compatibility program since then.”

"We had no idea what kind of challenges we'd run into, whether they're technical or legal or licensing."

But how did Microsoft overcome the seemingly impossible technical challenges that prevented backward compatibility on Xbox One in the first place? Ronald stressed that, once again, it was the community that initially inspired the team at Xbox to focus on making backward compatibility work.

“We had seen the feedback from the community that backward compatibility was one of the top requested features to try to add to the Xbox One program. But to be completely honest, we actually didn't know if it was going to be possible,” Ronald explains.

“If you look at the architecture of an Xbox 360 versus an Xbox One, they're fundamentally different architectures. And we didn't know if we were going to be able to emulate some of these games, or what kind of problems we would run into.”

Undeterred by the possibility that the team might hit a dead end, Ronald and a group of colleagues set off on tackling the monumental challenge set before them.

“We built a small team of some of our top engineers and we kind of squirreled them away,” Ronald recalls.

“We said, ‘Hey, give us a year. Let us see if we can actually make this work.’ And I remember the first time I saw an Xbox 360 game running – it was that moment where, all of a sudden, you believed it was possible.”

As Ronald reiterates, the team at Xbox really didn’t know if backward compatibility would even work, nor could they predict the other hurdles they’d face along the way.

“We had no idea what kind of challenges we'd run into, whether they're technical or legal or licensing. So it was an entire journey. Over that year, we really had all these amazing milestones where we started instilling more and more belief in the team and our ability to go do it,” Ronald says, clearly brimming with pride.

"We’re also kind of pushing these games further than they've ever been pushed before."

The team's belief led to a number of innovations that could modernize some backward compatible games, and it all started with Xbox One X enhancements. Using the additional graphical horsepower of the Xbox One X, Microsoft was able to bring 4K resolutions to 720p games like Red Dead Redemption and Final Fantasy XIII, along with many others.

On the newest Xbox Series X and S generation of consoles, things went even further. Microsoft introduced FPS Boost and Auto HDR, which could double and even quadruple the frame rate of older titles, as well as add high dynamic range to games that were released before HDR was even invented.

Not only did these technical improvements help transform original Xbox, Xbox 360, and Xbox One games into feeling new again – something that was typically only reserved for full-priced remakes or remasters – but these updates were completely free.

So will we see any more FPS Boost titles in the future? Ronald refused to rule it out but did explain why it isn’t as easy as flicking a switch.

“To be honest, we don't really know right now,” Ronald says candidly.

“One of the challenges that we have on some of the enhancements and the capabilities that we have is that we do all of this with no code changes to the actual original game. So, as we identify new techniques of enhancing and optimizing titles, oftentimes, we know it won't work on all games. And I think FPS Boost is a great example of that, where we're kind of tricking the game into running at a much higher frame rate.

“And some games it just works really well. But there have been other games that 99% of the game looks and plays amazing. But then we actually discover a game-breaking bug 80% of the way through or 90% of the way through,” says Ronald. “And a lot of times, we try to come up with solutions, and we see if we can work through those issues. But since we treat it as a black box, we don't have the ability to change the game code directly.

“It's one of those challenges. But we’re also kind of pushing these games further than they've ever been pushed before. And unfortunately, some of the techniques just don't work across all games.”

Digging up the past

"I will say every game is a unique challenge. And that’s one of the harder things to get across to the community."

As is human nature, the success of the backward compatibility program has ultimately led to one familiar question arising: why isn’t every game backward compatible on Xbox Series X and S? Much like FPS Boost, it isn’t as straightforward as you might think. 

Ronald admits that part of the challenge was that Microsoft, and the video games industry as a whole, hadn’t really designed games with future generations in mind, which posed a number of unexpected problems.

“A lot of the games in the original Xbox generation or the Xbox 360 generation, at that time, the idea of forward compatibility – and thinking about how these games will live on – was not part of the DNA of the industry,” says Ronald. 

“There would be titles that we would be working on, and we would get them technically working. But then all of a sudden, we’d realize all the different approvals that we would need: whether it's a publisher or developer or a license holder. 

“And that actually created a lot of work and a lot of challenges,” Ronald goes on to explain. “In some cases, when you think about the consolidation of companies, or IP being purchased, sometimes it's even difficult to figure out who you need approval from!

“But I will say every game is a unique challenge. And that’s one of the harder things to get across to the community. Because people are like, ‘Oh, well, you did this game, you should do that game’. Every game is a unique set of challenges and that's where a lot of the work goes behind actually bringing a game forward.”

Barriers to entry

"It’s a labor of love and it takes, in some cases, years to be able to bring these games forward."

Issues with licenses, publishers, and technical quirks would mean Ronald’s team could often start with a list of hundreds of games they wanted to add to the Xbox backward compatibility program, but with the understanding that they had no idea how many would make the cut or how long it might take. Some titles, as Ronald shares, have taken years to be added to the program due to the aforementioned issues. 

“When we started this last patch [over 70 back-compat titles were added on November 20, 2021], we actually started with a list of hundreds of games that we were going to go try,” says Ronald. “And we didn't know if we were going to get five [titles], if we were going to get 10 [titles], or if we're going to get 20 [titles]. 

“And to be honest, there are some games in the program that I just never thought we would be able to bring forward. It’s a labor of love and it takes, in some cases, years to be able to bring these games forward, but the team has always been really committed to doing everything we can for the fans.” 

Remembering the OGs

"He's now getting to experience the games that I loved when I was younger."

Fundamentally, it’s Xbox fans, young and old, who have benefited most from the backward compatibility program. But has it been worth it for Microsoft as a whole? Ronald refers to his own personal experience for an answer.

“Obviously, we’re really happy with the response to the program. And we've seen a lot of new players come into franchises they've never played before,” says Ronald. “My son, he's 13. His first Fallout was actually Fallout 4, and he's really started to love the world and the universe that they made. 

“For him to be able to go back and play Fallout 3, or to play Fallout: New Vegas. He's now getting to experience the games that I loved when I was younger, so it's just a great experience. I think it absolutely brings people back into the ecosystem. It rekindles people's memories and love for some of these franchises. And it also introduces new players to the games that we all love.”

Game preservation could shape future consoles

"When designing the Xbox Series X and S, backward compatibility was a tenant of the program from day one."

Game preservation has become a more prominent issue in recent years, specifically how video game manufacturers need to do more to ensure that the great games of the past can be enjoyed by generations to come.

Ronald says the team at Xbox is committed to game preservation, and that the backward compatibility program helped the team get a better grasp of how to handle it in the future. 

“Game preservation is definitely in our DNA,” says Ronald proudly. “I think over the course of this program, we've learned a lot about game preservation, whether it's technical decisions, the way that games are actually ingested into the catalog, the way that we sign contracts and deal with licensing, and whatnot. I think it's actually informing not only us but the entire industry of what we can do to preserve these games moving forward.”

Interestingly, Ronald also shares that Microsoft’s commitment to backward compatibility helped shape the Xbox Series X and Xbox Series S, and will likely influence the next Xbox consoles.

“When designing the Xbox Series X and S, backward compatibility was a tenant of the program from day one and actually influenced the design of the silicon, the design of the hardware. It was like, ‘Okay, how do we make sure that these games not only work but play better than ever before.’ So absolutely, as we think about future devices, as we think about future platforms, we're always thinking about what unique things can we do to enhance or optimize these games?”

Ronald rightly points out that it’s not just about making older games look at play better, though, but also about accessibility. 

“I think about something like Project X cloud [Xbox Cloud Gaming], and the fact that I can play a game that was written on the Xbox 360 on a phone. Trust me, when you were writing a game on the 360, nobody was thinking about a future where the game is gonna be running on the cloud. It can be streamed to my phone while I'm on the go, but my progression moves forward with me. So not only is it about optimizing enhancing games, but it's about how we can provide new ways for people to play these games.”

The Xbox team has been on quite the journey with backward compatibility, then. There have been numerous challenges from day one, but thanks to the support of the community and some dogged determination from Microsoft’s engineers, we’re now able to enjoy and rediscover these games once again. 

“A great game is a great game,” says Ronald. “It doesn't matter if it was written today, or if it was 15 years ago. We want to preserve that art form, and we want to just be able to reach more players across the world.”

We couldn’t agree more.
