Hello staff, nice to greet you. I'm here to share a video that you may not even see but I'll try anyway, I'm a fan of God of War 3 and I never had a PS3, thanks to you I can play it at a speed and graphic levels higher than the PS3, bravo to you. However, I have noticed a problem that I tried to share in the discord group but for some reason no one could understand me, I think I was a bit insistent about making a video to show what I saw but in the end they ended kicked me from the group unfortunately. Here I share it with you, greetings and thanks to you guys. kzbin.info/www/bejne/aJCnc4Gsltt8fpI

Floating Point Precision for Negative Integer Sequences version 14C-0012 Grouping Numbers Greater than Bitwise Negative Generating 12 Is one of the instructions of all time!! It's used when you need to group 2 buffers (compatible with arrays/lists) of negative integers of size -12.3333... bytes or smaller. It's a rarely used opcode, but can be found in programs that convert 0D Video Renders of 4D Hyperspace Simulations to 3D Videos, make JavaScript actually palatable (Note: Public builds were blacklisted due to the lack of web developer tears), solving web error 418, and Red Star OS to Temple OS compatibility (Not to be mistaken for 21gnbgng2100c41sinppf which is is used for Temple OS to Red Star OS compatibility).

Epxlanation on "disabled for better yields": They basically only expect 7 out 8 to work. No matter if that's the case or not. If all work they just disable one arbitrarily to keep everything consistent. AMD did that too in Desktop CPU during the late 2000s so some times you could get literally free performance (Except for slightly higher thermals and power draw) by re-enabling one. (sometimes required custom bios. But one company actually implemented that in stock for a while. don't remember which one.) Or random crashes if it actually was broken. That's what the 3 cores where.
@Deliverygirl6 ай бұрын
Disabling units is still very much done today, however now instead of disabling them in bios the transistors themselves are lasered off during the triage process when being manufactured. One of the reasons why the chiplet architecture used by AMD is so important is that it allowed to minimize losses from yields, it's a lot easier to manufacture smaller pieces with no defects and glue them together than to manufacture a massive monolithic piece of silicon with no defects.
@Jaker7886 ай бұрын
@@Deliverygirl Aside from large block cores. We also have GPUs that have more compute units or cuda cores but a percentage of them are disabled or were already bad, it's redundancy across much smaller parts of a chip compared to an SPU or CPU core The PS5 and Xbox both have redundant compute units for the GPU part of the SOC, but all of the CPU cores are expected to at least work within the designed operating frequency.

sometimes one core will be slower but not completely out of commission too.

I assume many of the developers back in the day who worked on the PS3 didn't either. A lot of making old software (emulated or otherwise) continue to work is to have things function even if the developer did it the "wrong" way. This runs the gamut from Factor 5's work on Star Wars: Rogue Squadron II, a game that used the Gamecube's RAM in such an unusual (but very efficient for the target system) way that it was one of the last games to run correctly on Dolphin, to downright incompetence like the recent Pokemon Scarlet/Violet releases that were full of major performance issues and visual bugs (which were emulated correctly in Ryujinx). Both Linux and Windows go out of their way to support software written in horrifying ways, because someone, somewhere relies on it.

Now here’s how the game looks/performs after applying an optimization and why.” That would really help laymen like myself get a better picture of what’s actually going on.

Usually these lines of code are performing a small instruction of the whole. Think of how you speak English, and how you don't need to think about the individual letters when you speak. If each word suddenly requires you to spell out every letter and describe its shape before moving onto the next letter, you can realize why that would massively slow down your ability to speak despite not affecting the accuracy or concept of what's being conveyed. If you're looking at stuff on the byte level, you can't boil it down to "a whole" and you have to take things as atomic as possible.

When developing an emulator they don't really need to know how the game engine puts the game together step by step, they just need to make sure the system architecture runs efficiently and (fairly) accurately, and if there are specific things that don't work then they have to find the pain points and fix them.

I literally tested RPCS3 for the first time to experience the original Nier Gestalt after finishing the Replicant remake, and wondered why it ran so good, i imagined some recompilation goodness, but god this video is a CPU geek paradise, thank you!

The same crackhead floating point format as the PS2 uses lmfao
@lpfan44916 ай бұрын
I still love that Dolphin emulator of all things had to implement it because the curse upon this realm that is True Crime: New York straight up ported the PS2 format over to GC because "why not?" And it's entirely worthless too because it is a bad port of an already unfinished game, just pure meme material.

Very topical video for me right now. I'm working on an ARM emulator for x86, so this sorta stuff has been on my mind. I never thought to use LLVM in the context of emulation, but that's actually a great idea. Definitely going to consider letting it handle the IR and native code generation, it'd save me a lot of effort.
@MrWhatcookie6 ай бұрын
The one drawback with using LLVM is that the time to compile code is pretty long. RPCS3 mitigates this by falling back to interpreter while other threads compile the SPU blocks.
@meneldal6 ай бұрын
The good news is it's definitely a lot easier to run ARM (at least the 64b version) on x86 than the other way around, since most of the instructions will have a direct equivalent, and performance is achieved by finding the right instructions to merge together. Old ARM with conditional instructions on the other hand is a lot more painful but you can probably get away with poor performance on most of them since their usage rate is so low.

Man low level programming is just crazy to me, I'll stick to my weird and wacky Javascript frameworks 😅
@jc_dogen6 ай бұрын
you're sabotaging yourself thinking this way. this is far from typical. low level programming is not inherently super hard or anything. even normal assembly code is honestly pretty easy to learn, but almost nobody even goes that low these days.
@Deliverygirl6 ай бұрын
+1 to what jc said, emulation and instruction set micro-optimization is edge case stuff, you can get into low level programming without having to delve into the magic like shown in this video, probably what will throw you off the most is how ugly the syntax tends to be for low level stuff, if you work with high level languages like javascript you'll probably be used to the high abstraction with very descriptive naming schemes for methods and data structures, whereas in low level programming everything looks like magic from everything being an abbreviation of an abbreviation.

Impressive video editing for the first real video on your channel! The only thing I could recommend is that when you put text on screen, add some sort of static or blurred background behind it for easier readability. This info is best digested in the blog format you've already linked, but video is definitely the gateway to a larger audience. Cheers and good luck on finding a job. Commenting for the algorithm!

Excellent video, I learned something about SPUs that got me curious about my own RPCS3 instance as well as why other CPUs (running AMD + nvidia) more advantage
@luigiymario2xd6 ай бұрын
Nice! I just realized my AMD top of the line cpu does have AVX-512 so I can take advantage of this for PS3 emulation 😎

This video is tight. As someone who just started learning the very basics of python I’ve wanted to see how the simple things I’ve learned actually translate to programming in video games. While I don’t quite precisely understand what’s going on it certainly is insightful to see a more in depth and direct explanation of how not only specific aspects of ps3 code functions but the improvements you can make with emulation. Very cool thank you
@mayelop44785 ай бұрын
This just reminds me of my failure of when i tried taking an assembly class and got discourage by all the bit conversion and assembly code you have to learn just to make sure a controller port works in a computer. But I wont lie, this video makes me want to give it another try.

There's so many stuff inside PS3 and I'm amazed how game dev utilize it and also I'm amazed PS3 can be emulated with so many things need to convert to make it work with any current PC hardware. I always thought that emulation development is only need to recreate the PS3 CPU using line of code, but now I understand that it's way more complex than that.
