Revolutionizing N64 programming! (SM64 Audio Optimization) (SOURCE CODE Download)

[@KazeN64]

100 points to whoever can tell me what this technique is actually called because I'm pretty sure I'm not the first to invent this.

[@abowden556]

Why is it all the big dick programmers are doing their best work on ancient hardware? More of a challenge? It used to be 8 bit, at least they are now doing it on 32-64 systems. I do wonder if this 'cache blocking' technique is worth applying to modern systems though... In principle I don't see why it wouldn't be, not having to got from L1 to L2, or L2 to L3, and especially L3 to RAM is always a huge boost.

[@jjbirb9596]

its called blockingcache obviously

[@Rubbe87]

Holt Kazed

[@LunaTheFoxgirl]

It's a data locality optimization, a lot of games especially bigger AAA titles that use streaming also need to heavily optimize to avoid cache misses, which you do by putting stuff so that they can be fetched in 16 KB blocks (on x86_64, on arm you can go as high as 64k blocks).

[@Kniffel101]

@@abowden556 You can be rest assured that engine developers of any of the big game studios, heck even many Indies, do constantly think about hitting the cache as much as possible. Otherwise games wouldn't look and run as well today as they are. It's likely that it's not as "hard core" as Kaze is doing it, but that varies from studio to studio. Also on modern systems the caches aren't the only bottleneck.

as someone who makes custom music for MM Rando, I've actually used quite a few of the unused functions when creating sequences. it's always amazed me just how much stuff just never got used in _any_ "ASEQ"-based game. this code goes mostly unchanged and contiues to have the same functions in every first party game up to and including Dobusu No Mori (the original Animal Crossing game for N64), and every single one continues to use only the most basic of the music functions. the only thing that any of the games do that even comes close to being an interesting use of the format is how OoT deals with Hyrule Field's music.

[@Bonezones]

What does OoT do with Hyrule Field?

[@angeldude101]

Are you saying that if Kaze isolated just the audio subsystem improvements, it would be able to be ported to other N64 games like OoT and MM?

[@darkychao]

@@Bonezones OoT's Hyrule Field is not just one continuous song, it's a bunch of separate sequences and they transition from one to the next procedurally depending on the situation. so, when you're moving around the field it plays adventurous music, when you're standing near the water it plays more calm music, when you're near an enemy it starts playing suspenseful music, and when you defeat the enemy it plays triumphant music.

You're doing absolute wizardry with the code. I'm sure at least some of the original programmers on the N64 have been watching - and saying they could have done it if they had more time. Just think what could have been done on these old systems if everyone was as talented and had the time (or budget for a released game) as Kaze.

[@AstorEzequiel]

And don't forget the current knowledge available. Back when they made games for the N64, all programmers had basically small knowledge about this new system and the engines

[@HerbaMachina]

@@AstorEzequiel any in house developers at Nintendo would definitely have had access to documentation files denoting the features of the architecture and engines, it's not like this was some magic new thing that popped into existence without a designer.

[@AstorEzequiel]

@@HerbaMachina Point taken! Still, I think there's a vast difference of knowledge between the programmers and the +20 years of knowledge that we have right now. One example of that are the speedrunner community and their exploits! And let's not start talking about the TAS!

[@Quaker763]

Just FYI, the term you're looking for with "performance lottery" is actually known as "Code Locality" :P GCC actually has a few function attributes you can attach to instruct it to put "hot" functions into a special section to improve the locality and cache friendliness. Excellent work btw

[@Cyberfoxxy]

The Ocarina of Time and Mario 64 decompilation projects are the greatest gift in decades. I recently found that Jak and Daxter has been Decompiled too. "Project Jak".

[@AROAH]

I wonder if this is the same technique used in Conker’s Bad Fur Day. The dev commentary videos they did, years ago, mentioned that someone had written a way for the audio to run on “a very fast part of the N64 that was very small.” Sounds a lot like the instruction cache.

[@darak2]

Your whole series of videos is extremely inspiring and I wish more programmers would know about it. Especially, the notion that compiler optimizations can and will sometimes work against you is eye-opening: compiler writers often make assumptions about the target architecture that may not represent it accurately, and this is especially true of compilers like GCC or LLVM which target a large number of architectures. I'm sure a lot of programmers will be fast to dismiss those facts, arguing that the N64 architecture is just weird and those kind of problems would be no issue in a modern, sane architecture. That would be a fatal mistake. If anything, RAM access is MORE expensive nowadays (compared to register ops) and, in fact, modern processors are even more exotic, as the fastest implementation for many problems usually involves using extremely specific wide vector ops the compiler may not even know how to emit outside of an intrinsic. At the end of the day, the compiler is not a magic wand.

[@vyor8837]

Ehh, a lot of this wouldn't be an issue due to how much more cache CPUs have now. The MIPS architecture is also rather unique in that unrolled functions, even those tgat fit in the cache, are slower than inline ones. This isn't the case on modern architectures thanks to their out of order nature.

Learning about technical quirks of the N64 like the slow-ass RAMBUS really hammers home why it was hard to develop games for and why so many games had low framerates. You must be a really skilled programmer to do this, Kaze.

[@Vextrove]

Optimize by removing all the audio code. You don't need music!

[@Mante_killa]

Love you and thank you for your dedication to the n64

[@donchill2k]

i grew up with the n64, please never stop optimizing, i wanna replay most of the games at one point

[@eliteteutonicknight1]

Amazing stuff as usual, Kaze. ❤

[@steelplasma256]

Imagine loving a game so much you rewrite the entire source code better than the programmers could ever.

[@eelkir]

You're the first person I found that acknowledges the headphone mode! Always wondered what it did exactly

[@Arthurtilly]

I don't understand why you keep hooking your PC up to a CRT monitor in order to show off your mod footage. Aren't you just ruining the graphical advantages you get from using the PC Port? Seems like an odd choice to me.

[@CeIIHunter]

This is satire right

[@CeIIHunter]

I can only assume it's not so let me just say he didn't hook his computer up to a CRT doofus. He's running his rom hack on an actual N64 to show off the performance. Y'all need to listen better

[@linuxization4205]

1. That's connected to a Nintendo 64. 2. This was only a couple times, it shouldn't bother you. 3. He also showed PC footage, now quit whining.

[@Arthurtilly]

@@CeIIHunter No, if you were a true Kaze fan you would know that his rom hack is on the PC Port.

[@CeIIHunter]

@@Arthurtilly you never know these days man

[@user-vq2gq2hk2b]

Thank you so much for everything you've done for the sm64 community Kaze! And for keeping my favorite game of all time alive. You are a legend bro

[@crumpet_]

Such great videos! I love romhacks and the homebrews, seeing what you're doing is fascinating. Lots of problem solving and patience obviously goes into your work. Thanks for these vids 👍

[@brookestephen]

looks like lots of functionality in the game is now considered architectural today. I'd love to see the game ported to X3D or Three.js, where lots of sound and motion functionality is provided by the rendering engine.

[@harmhoeks5996]

I think the .c is way more low-code

[@zenbyo]

I love programmers who go back to really push the limits of these machines. These videos you've made and the programmer who made his own R-Type (turbografx) modifications to get R-Type running on SuperGrafx are so cool.

[@Kaimas7]

Sorry for my ignorance but has anyone ever before tried to reverse engineer N64 games before (for optimization purposes)? This is so cool. This is so amazing to watch. Danke for your work!

[@Candlehyde]

I know the tinkering done to the code directly goes back into expanding the game further via improved visuals and all, but I honestly really like just hearing, or reading, about people putting in the work, cleaning up and optimizing what's already there. Prefer that over things like new features, bigger worlds etc. It takes a lot of learning, patience and care, and I have nothing but respect for that.

[@RENhoekLOUD]

Solo puedo decir una cosa de una sola palabra GRANDE, eres un grande.

[@sammlerkiste7970]

My god whats next? How i optimized the n64 hardware? Like always a crazy job man and a big thumbs up!!!

[@monorail0]

Love that your voiceover audio also got an upgrade this video

[@death-disco]

I love your videos so much. I'm also into 'retroversing', but in a different way, for different platforms (long story). If you had a subscription service that went into detail about everything you are doing, I'd sub in a heartbeat.

[@Yoshistar95]

I love the funny images passing by when you just keep talking about what you have done optimising code, keep at it!

[@lpfan4491]

Honestly, this is really the most amazing thing I have seen in years. If even a fraction of the potential optimizations to SM64 apply to other N64 games in a diffrent form, then I can imagine 30 FPS games(Or heck, 20 FPS in rarer cases like OOT) will never framedrop ever again. Some people claim that decomping doesn't matter outside of romhacks, but lord were they off the mark.
