Progress Report: April 2019

Welcome to April’s Progress Report! Firstly we would like to apologise for the delay in publishing this report. RPCS3’s progress reports are solely written by volunteers and a few of our regular writers could not contribute to this report due to personal commitments. If you hate seeing RPCS3’s reports get delayed and would like to contribute to them, please apply here.

This has been a very busy month, which saw many contributions from our regular developers and even a few newcomers. Major improvements have been made to RSX emulation by kd-11, fixing the texture cache and improving on the shader decompiler. Meanwhile, eladash in his usual style, fixed a multitude of bugs relating to savedata handling and the PPU/SPU interpreters/recompilers. Numan (Inviuz) implemented a fringe syscall needed for Metal Gear Solid 4 to boot and Nekotekina squeezed quite a bit more performance out of the SPU LLVM path. To also improve the visual aspect of the emulator drysalter created two beautiful new themes and lastly GalCiv expanded DualShock 3 Support to Linux. These and many more improvements have all contributed to making RPCS3 both a better piece of software and a better emulator, moving a bunch of new games into the Playable category.

In addition to the following report, further details of Nekotekina and kd-11’s work during April and upcoming contributions can be found in their weekly reports on Patreon. This month’s Patreon reports are:

This month RPCS3 reached another milestone in game compatibility. It’s the first time that the Playable category surpasses 40%! As a result, the Ingame and Intro categories see an equivalent, while the Loadable category goes down to 29 games. We are also gearing up to undertake further maintenance to the compatibility list by identifying and merging duplicate entries in the coming months! For a more detailed look, you can view the compatibility history page to see exactly which games had their status changed this month.

Progress Report: March 2019

Welcome to March’s Progress Report! If you were left wanting more after last month’s report, then your wait is over. March saw massive strides in all facets of the emulator as multiple work-in-progress pull requests from our regular developers were finally completed and merged. To start things off, Nekotekina implemented a new LLVM-based SPU interpreter, updated the LLVM submodule to version 9 and fixed the “Out of memory” errors faced by some games. On the other hand, kd-11 continued his mission to improve the RSX texture handling which fixed issues faced in over two dozen titles while GalCiv implemented native support for the DualShock 3. Finally, elad335 made a host of improvements to various core components improving performance and accuracy in an assortment of titles, most notably God of War 3, when running on Windows.

In addition to the following report, further details of Nekotekina and kd-11’s work during March and upcoming contributions can be found in their weekly reports on Patreon. This month’s Patreon reports are:

Conclusion

This month saw more maintenance work done to the compatibility list where duplicate game IDs for the same game were merged into one single entry. A grand total of 118 threads were merged allowing for a fairer representation of RPCS3’s compatibility at this time. Adding to this, our community of testers continued their efforts in acquiring and testing obscure titles that had not been tested recently. The results of this revealed that many of the titles in the Ingame and Intro categories were now indeed Playable and moved according. Thanks to the dual effect of both efforts, the Playable category saw a marginal increase while the Ingame and Intro categories saw a sharp decrease in total number of games listed. Finally, thanks to elad335’s improvements to sys_vm, Doom 3: BFG Edition moved from Nothing category straight into the Playable category, leaving just two more titles in the Nothing category!

Progress Report: February 2019

Welcome to February’s Progress Report! This month saw smaller number of contributions from our regular developers as most of the improvements were still a work-in-progress that required further tweaking before they could be merged in the upcoming months. That’s not to say this February didn’t have big improvements though. On the contrary, this month kd-11 finally implemented the much anticipated On-Screen Keyboard while GalCiv managed to emulate multiple PlayStation 3 accessories using regular controllers. If that wasn’t enough, thanks to the multiple other performance improvements to the emulator, exclusive titles such as Genji: Days of the Blade have seen a huge uplift in performance.

Conclusion

This month saw RPCS3 reach another milestone in game compatibility with the Ingame and Playable categories cumulatively crossing 85%! This was largely thanks to the conscious efforts of testers to retest all games in Intro, Loadable and Nothing categories and report issues faced to the developers. Once provided relevant causes, our developers were able to fix issues plaguing many of these titles. Their efforts paid off with the Intro category decreasing by 66 titles. But this is just the beginning, with further work being done to improve these titles.

Conclusion

Over at our forums, a few user and moderators have come together to acquire and test titles that have not been tested recently. Our developers have also been hard at work debugging niche issues that seem to prevent a few titles from progressing ingame. The results of their targeted efforts gives us veracious compatibility statistics from which we can see a big decrease in Intro and Loadable categories and a corresponding increase to Playable and Ingame categories.

Progress Report: December 2018

Welcome to our (2018) December Progress Report! We are extremely happy to finally push this report out to you guys after the many delays, for which we tried to make up with other kinds of updates along the way. We hope that you’ll enjoy our deep dive about the last month of the past year, and find its stories equally as intriguing.

December has been an absolute whirlwind for RPCS3 with improvements made to various parts of the emulator. Nekotekina greatly improved performance with the introduction of Approximate xfloat while kd-11 fixed a wide variety of graphical issues affecting multiple AAA titles. Apart from our full-time developers, our regular contributors also made a plethora of improvements to the texture cache predictor, cellCamera emulation, controller/mouse support, GUI and tons of bug fixes. We’ve tried to detail as many as we possibly could in this report. So without further ado, let get into it!

In addition to the following report, further details about Nekotekina and kd-11’s work during December and their upcoming contributions can be found in their weekly reports on Patreon. December’s Patreon reports were:

Conclusion

This month saw improvements to various aspects of the emulator and the compatibility list is no exception. At the start of 2018, the compatibility list was revamped to allow us to merge multiple game IDs for the same game into one single entry. This helped reduce duplication of entries and enhance the quality of the statistics we provide. While we were able to merge IDs of different regions together, due to the way the compatibility list database was structured, titles with multiple IDs from the same region could not be merged and hence were shown as separate entries. Not wanting to leave the job half done, AniLeo refactored the compatibility list once again this month to now allow us to merge IDs from the same region as well!

With this change, we can eliminate unnecessary duplication entirely and significantly improve the quality of our statistics to properly represent the amazing progress made with the emulator. If you take a look at the metrics for this month, you will notice that the number of games has decreased across all categories. This is solely due to the above mentioned revamp of the compatibility list. However, if you take a look at the compatibility history page, we can see that the Playable category has increased by over 15 titles and Ingame category has increase by over 30 new titles. The nothing category also reduced by one, bringing the total to just 3 titles!

Progress Report: October 2018

Welcome to October’s Progress Report! Thankfully, there have been no major delays in publishing this time around, and we hope to continue gradually closing the gap even further in the future.

On the other hand, since both of our main developers were busy this month doing heavy refactors and rewrites in the background, not all of the changes are ready to be showed off just yet. While Nekotekina’s current efforts aren’t about yielding direct and spectacular changes to begin with, we did do a write-up about kd’s changes and another graphics related PR from ruipin here in the Upcoming section below.

This isn’t to say that October was without any changes, as one entry of a cult-classic and previously PlayStation exclusive AAA series, Yakuza, just hit playable this month! For this, and more, let’s dive in and see what happened during the month!

Progress Report: September 2018

Welcome to September’s progress report! Firstly, we would like to apologize for the delay. Our progress reports are written by voluntary writers and sadly most of them were unavailable to contribute this month. However, there is a silver lining here. The additional time we had gave us a unique opportunity to convert this month’s progress report into a technical exposition hybrid!

We’ll be featuring a deep dive into the inner workings of the texture cache in RPCS3, and how it was improved thanks to the contributions of ruipin and Nekotekina. We will also uncover the wide variety of improvements that kd-11 made and showcase some massive improvements to various AAA titles. Without further ado, let’s jump straight into September’s irregular progress report!

In addition to the following report, further details about Nekotekina’s and kd-11’s work during September and about their upcoming contributions can be found in their weekly reports on Patreon. The month’s Patreon reports were:
