    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.

    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).

    @@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.

    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.

    the main change is usually panning. basically, any code that says "pan this code by [x] amount to [y] direction" will be modified to exaggerate or reduce the panning intensity depending on developer intention. some games also add phase inversion to some sounds in headphone mode (not sure about n64 titles, but i've heard it in GBA titles) on one of the channels to create a fake "surround" sound.

    that 562mb/s is something they came up with by calculating how much the RAM could transfer under ideal conditions, i've been told. in practice you will never be able to write/read that many bytes though. reading from the zbuffer and filling pixel colors for a whole 320x240 RGBA16 screen takes the RDP just over 4ms. that'd put the actual practical speed you could get under ideal conditions within the whole system somewhere around 60MB/s unless there is a faster way to move bytes that i'm not aware of.

    Actually, yeah it would be. I do compiler development myself, and given that the N64 is an unchanging target, being mindful of these limitations during optimization time would be important in the design of the backend. It's not impossible to do either, but it would likely look a little unorthodox.

    That's pretty insane that you were able to get so much out of the audio processing time. Impressive as always-- and I find it very cool that you're able to diagnose what the original programmers did with the source code, such as running it through that source-to-source optimization, just based on the decompilation. I'd love to hear a bit more about all those unused features in the audio library. Was it perhaps a library that they ported in from somewhere else, or was there just an audio guy at Nintendo with really big ideas, or maybe they just wanted to have all that extra functionality for just-in-case future-proofing? Very interesting. It seems to me that if there's one part of game engine code that might have survived through many years and into future development libraries, the audio code is a pretty good candidate, so I think the most likely reason for all that extra bloat is that they had written a comprehensive library to use going forward in many other projects into the future, but that's totally a shot in the dark. Thanks for the video!
