July like every month before it this year set a new record in the number of improvements that happened. Mostly centered around bug fixes and compatibility improvements it is safe to say that if every single improvement were to be covered in great detail this progress report would take more than a month to finish. Therefore the format is now going to change a bit. This report will focus on some major emulation improvements and it will explain what these entail in general. Thereafter a few select more interesting games and how they were improved will be covered. Every improved game will not be covered because there were simply too many, and evaluation of earlier reports indicate that it isn’t interesting content either.
First of all are the compatibility database statistics for the month of July. Take note that the last database update was performed a day before the major emulation improvement known as “LLE gcm” was merged, meaning the hundreds of games improved from this are not listed in the figures below, or even on the compatibility database yet.
May was a very eventful month for RPCS3 as we saw significant core and performance improvements. The goal of this progress report is to highlight some of the more notable or interesting developments of the project. The report will start by showcasing a selection of games that were improved in one way or another. Thereafter we will summarize what work each contributor did this month.
kd-11 joined Nekotekina’s Patreon
You can read about this in more detail here.
The short version is that kd-11 is an extremely talented graphics developer who has helped RPCS3 since January of 2016. Without his work RPCS3 would not be here today. It goes the other way around too of course, without the significant core accuracy and performance improvements by Nekotekina we would not be here today either. Therefore it make sense for two great minds to join forces. With the generous Patreon support kd-11 will be able to acquire new hardware for development and testing. On the short term purchasing list is a modern NVIDIA GPU, a modern AMD GPU, and possibly a Skylake+ laptop of some kind. This would allow kd-11 to fix specific issues on these platforms. Not many people use RPCS3 with integrated Intel graphics but they are technically fast enough (for now at least). The problems lie in very very buggy Intel graphics drivers which is why it would help to have direct access to it.
Check out this video below, it highlights some games that saw performance improvements from “the secret build” which was a huge general graphics rework, with focus in particular on Vulkan.
Veteran RPCS3 graphics developer kd-11 is joining Nekotekina’s Patreon. kd-11 has worked on RPCS3 since January 2016 and has since then fixed countless bugs in all graphics renderers and implemented a lot of missing functionality. Without his dedicated work, RPCS3 would certainly not be where it is today.
As you know lead core developer Nekotekina, who has worked on RPCS3 since 2013, launched his highly successful Patreon in January this year. Thanks to the overwhelming amount of support, he has been able to work on RPCS3 full time for 5 months now and the progress he has done is staggering. The RPCS3 team has discussed the best course of action for the road forward and have decided that the time is now right for kd-11 to join Nekotekina’s Patreon in order for him to obtain hardware necessary for development and testing.
As kd-11 works on the graphics side of things, especially the renderers using OpenGL, Vulkan, and D3D12 (Direct3D 12), modern hardware is required for development and testing. Ideally, he needs a modern AMD, Nvidia, and Intel GPU to easier identify bugs specific to one platform. Furthermore, kd-11 works as a consultant and therefore has the possibility to accept or turn down certain jobs. If support on Patreon reaches a certain level, he may be able to spend more time on the project.
April was a very eventful month for RPCS3. The goal of this progress report is to highlight some of the more notable or interesting developments of the project. The report will start by showcasing a selection of games that were improved in one way or another. Thereafter we will summarize what work each contributor did this month.
Since the last progress report, approximately 18 authors have made 104 commits, added 9,621 new lines of code and deleted 1,904 lines of code.
This is the last real PlayStation 3 game and it also happens to be highly popular. Let us take a look at a few things.
People often ask what kind of CPU is needed to run this game. The answer is that no CPU is truly fast enough right now, but if you enjoy playing games at 10 FPS or so, then feel free to get a CPU with a lot physical cores. See the screenshot below for the motivation behind this statement. Of course in the future when RPCS3 performance is improved such an extreme CPU likely will not be required.
March 2017 beat the previous record set by February 2017 as the most eventful month in the history of the project. So much happened that even this colossal progress report can only begin to scratch the surface.
First of all, lead RPCS3 developer Nekotekina reached the $1000 goal on Patreon, securing his long time commitment to work on RPCS3 full time. This was the direct result of the massive amount of attention the project got when two popular games were drastically improved this month. First, Demon’s Souls went from crashing in zero seconds to going ingame and almost being playable. Second, the cult classic Catherine received significant performance improvements and now runs with practically perfect graphics and performance. The two videos of these games received over 200 000 views on the official RPCS3 YouTube channel. Even the famous YouTube personality, TotalBiscuit was impressed with the progress, and the killing of the notorious Demon’s Souls boss Vanguard in RPCS3.
Of course the hundreds of videos posted by the community on YouTube, different forum posts, Reddit submissions, and so on, have contributed greatly to the massive growth of the RPCS3 community. In fact, new developer Inviuz aka Numan was one of these people who recently discovered RPCS3, spent a lot of hours reading the code and debugging Demon’s Souls, and finally getting it to boot for the first time. Oh and Red Dead Redemption also went to the main menu thanks to this, and some graphics improvements by kd-11. This showcases one of the most important strengths of RPCS3 being free and open-source software and it is very likely that more and more people will join the project in the future and contribute changes both big and small.
Since the last progress report, approximately 17 authors have made 115 commits with 6,831 lines of code added, and 4,471 lines of code deleted. And some significant improvements are still in the pipeline but have yet to be merged.
The progress report is mainly split into three different parts. First we will take a closer look at what each pull request this month did, and show a few practical examples. Thereafter we will take a look at a selection of some interesting games that were improved this month, though this is just a small slice of the hundreds upon hundreds of games that received small or significant improvements this month. Lastly we will take a look at some of the upcoming changes before rounding of this monthly progress report.
It finally happened! The PlayStation 3 emulator RPCS3 has launched one of the most iconic games on the platform: Demon’s Souls. Are you curious to know how it all happened? What the developers went through? Welcome to this first of hopefully many to come developer logs where we will now tell you everything.
It all began in our Discord channel where a user going by the nickname, Numan approached us with some interesting news. He claimed to have conducted a detailed investigation of what Demon’s Souls was trying to do when it was crashing one second after booting. He drew the conclusion that the game was trying to allocate memory pages of different sizes, access levels, and different attributes. When the game then tried to access a specific memory address, it crashed with an access violation. Consequently, these discoveries lead to a more accurate implementation of the function sys_memory_get_page_attribute() which was responsible for this particular crash. Suddenly the game booted up in RPCS3 for the first time ever and showed a loading animation!
February 2017 was one of the most eventful months in RPCS3 history. Earlier this month we reached the first Patreon goal of $500, thus ensuring that Nekotekina can continue to work on RPCS3 full time for the time being. A total of 17 authors have pushed 127 commits to the master branch, with 9882 lines of coded added and 6575 lines of code deleted. This represents several hundred, if not thousands hours of work on the project, and it really shows.
In this progress report we will take a look at what each person has been working on for the past month, and highlight some of the more noteworthy changes. This is however far from a complete list of contributions and improvements. Several people in the community have tested hundreds of games, reported several issues, made YouTube videos and supported people on Discord. Nekotekina, kd-11, and the rest of the RPCS3 team would like to thank everyone for their contributions to the project.
A lot of things happened in January, specifically the second half of the month. As you all know, veteran RPCS3 developer Nekotekina had the opportunity to launch a Patreon with the goal of working on RPCS3 full time, and right now he is doing so.
At the time of this post and since the 1st of January, Nekotekina has made 54 commits on GitHub with various changes and improvements. In total, for the past 31 days, there were 82 commits with 6,726 lines of code added and 4,867 deleted by 11 authors. For example:
