[@wavefront9221]

Now we need somebody to do the unthinkable and port this to the Sega Saturn

[@davy_K]

@Fat Chocobo Yeah. Will be a tough ask off the PS1 or Saturn without RAM expansion due to the cartridge format's advantage of fast data access. Plus the N64's processor was just under 100MHz which was a big deal back then. Never mind the different architectures re graphical abilities - didn't the Saturn use quads instead of triangles? I don't see the attraction of running it on a console anyhow - seeing it running on a high end PC with brand new remastered graphical assets would be wonderful.

[@BenignStatue71]

@@davy_K The Saturn's "quads" are literally all sprites - hence being quads, as sprites are quadrilateral. You can render a tri by just making one side of the spite have zero length.

[@davy_K]

@@BenignStatue71 Yeah you can....but it looks like shit when you do that. There are a few online articles about PS1->Saturn ports that did just that. It's a moot point anyway since OoT was a cartridge game which would be extremely hard to implement on the PS1 and Saturn simply because of delay is shifting data from a disc. I'm sure an emulated PS1 or Saturn could make a job of it provided it was overclocked and removed any read delays- but what would be the point? It's always nice to see just how far stock consoles can be pushed with modern tricks today..I suspect OoT would be a step too far. M64 and OoT were probably why N64 was cartridge based.

[@BenignStatue71]

@@davy_K Nintendo selected cartridges because it wasn't something you could have just any factory manufacture, unlike a CD - you needed to have each individual cartridge produced by Nintendo or you couldn't release the game. Nintendo gets both an up front manufacturing cost *and* individual sale royalties. Read speed and access times were a side effect of cartridges that provided at least some argument to developers; they were otherwise just an extremely costly medium between the consumer who owned an N64 and their game. The fact that the N64 DD still used a proprietary format makes Nintendo's greed pretty evident - for the same capacity as Resident Evil 2, you could get a diskette that might have been cheaper to produce, but still only Nintendo could manufacture. It doesn't matter if the actual price of manufacturing each cartridge goes down, only Nintendo will make it and they can set the price at whatever they want.

[@davy_K]

@@BenignStatue71 Well. I only partially agree with that. Certainly their publishing and licencing model suited the cartridge format which is what they loved as it made a shed load of money, pushed a lot of risk onto 3rd parties and let them control the release schedule. However , as I guess you know, the CD drive debacle with Sony and Philips is proof that Nintendo experimented with the format. Miyomoto hated loadtimes and Mario 64 and Zelda : OoT would have been, to his mind, (or to anyone else who has really compared the games available across the 3 platforms) heavily compromised by the limitations of the CD media's access speed. If any further proof is needed - no game on PS1 and Saturn came near to those games in terms of 3D world building and the rich control scheme required for accurately navigating them in a go-anywhere fashion. The transitions between levels in M64 and the open areas and dungeon load and transitions of OoT are testament to it. They simply were not possible on those machines, otherwise we would have seen something attempting to recreate them. The best they could do was create environments made of corridors that gave a limited (albeit clever) illusion of 3D, but very little else.

[@seanmcgroty2248]

> Surprised that decompilation without a written spec and a second clean team is considered beyond legal challenge It's not, people are saying this because they want it to be true and their understanding of copyright law is colored by that. You're absolutely right that it is a derivative work. The definition of "derivative work" under US law is very expansive: "a work based upon one or more preexisting works, such as a translation, [...] or any other form in which a work may be recast, transformed, or adapted." Binaries (object code) are protected because they are themselves derivative works of the source code. It's possible there is a fair use exemption here for educational and commentary purposes, but as with any other fair use claim, it is something that can only be definitively evaluated in court.

I can only imagine the 2D backgrounds becoming 3D models and HD textures, as well as importing the 3DS remaster models, with modern controller support (to make free camera movement on temples and open fields) with support to Widescreen and 60FPS. Maybe even Raytracing... one can dream.

the same engine thing is also not really true. oot may have started as a fork of sm64 in the very beginning, but with both games decompiled its pretty clear that the code is not very similar at all. audio is the closes thing and that was probably somewhat of an external library already

[@arnox4554]

Now it's time to decompile Perfect Dark and see if it can possibly be optimized any further. I doubt it since OG Rare were absolute fucking chads at development and pushed that system to its absolute limit.

one thing this should be brilliant for is making a well balanced hard mode - such as making the monsters take more hits, move faster, etc. This game is so good, it would be really fun to reexperience but with a harder twist.

Theyre working on mario kart 64 and a lot of other games.

[@aaroninkinen521]

it would bring me sooo much joy to see this game come back full swing skyrim levels with this modding capability

[@SolTheCleric]

Before opening the video I was like "I can't wait to see how many times MVG will pronounce Ocarina as Ocaryner". I was not disappointed. 😄 I'm curious to see how many glitches and in-game exploits will still work with this version and how many of them will be "patched" as a side effect.

[@Ashe_S_]

If they do the version the speedrunning glitches are done on like they did this one, with matching hashes, then it *should* behave exactly the same. The only reason it wouldn't is if some weird hardware bug was causing any of those, which I don't think should be the case.

[@user-yr1uq1qe6y]

“Ocarina-r-of” Lol, this is exactly what went through my head when I read the title!

[@beardalaxy]

If I remember right, the debug version is very similar to the GameCube version? Just running on an N64 instead of a GameCube. So whatever glitches are present in that will be present here. Someone could theoretically fix them, but OoT glitches are usually things that need to be triggered on purpose so it's hard to imagine anyone actually doing it.

[@NFITC1]

I've been involved in a similar project for Final Fantasy VII (PC 1998). It's legal as long as two things are observed: 1) don't use that code for any commercial project (anything you make a profit off of) 2) don't use any of the original assets in the packaged game. I can make new models, textures, SFX, music, etc. to represent the original content, but I can't use anything on the discs it came with. Utilizing these restrictions you can recreate the game for use in any OS and even optimize performance and fix bugs.

[@sr.alligator7569]

I've always been fascinated with decompilation and reverse engineering projects in older video games, I hope to see PC ports of the original PS1 Spyro games one day.

[@TrevorAvrett]

The youtube video, "Super Mario 64 RT: Full ray tracing" by Digital Foundry does a decent job showing off the potential here. Can't wait to see recompiled Ray Tracing done with OOT

[@saricubra2867]

I'm more excited for +30 fps, the original N64 zeldas are unplayable by that extremely low framerate.

[@MegaManNeo]

Thanks for explaining why they went with a z64 ROM of Master Quest, that part confused me. I am actually not a huge fan of OoT but given what is possible with Mario 64 also, I'd love to see a 16:9 60fps version with HQ models and potentially a dedicated VR version either for SteamVR or the Quest/2.

[@abdelll9737]

You’re one of my favorite KZbinrs. I wish you uploaded more videos.

[@danceswithmetroids162]

This kind of work is so important for game preservation. The copyright holders have an unfair amount of power to dictate the manner in which legacy content is available, if at all, and these kinds of projects ensure we don't have to put up with anti consumer practices and vault-keeping. Now let's decompile DK64 so we can access the Tag Barrel from the start menu

[@SockyNoob]

Copyright and DMCA laws need to be revised to include games as historical media. The US government already has books, music, and films in archives after a certain age. Video games are nearing that age

[@heliusuniverse7460]

It would be hilarious if someone found and fixed the memory leak that made the expansion pak necessary in DK64

[@Criticmasterz]

Excited for more decompliations

[@wilsonicsnet]

This is great. I can see the randomizer community benefiting from this one greatly.

[@beardalaxy]

Digging the SH2 shirt! I might actually mess around with the code, it's the first time I've seen someone lay out how to do something like this so easily instead of just saying "just build the file bro" so thanks for the succinct tutorial :)

[@RC2225]

I think those reverse engineering projects are the best way to bring old games to modern hardware and be independent from emulators. I know not every game can get such treatment and a bad or good remaster. For some old games if a publisher or dev would release the source code its still possible to sell the assets and have maybe an active community which maintains the underlying code. They could even sell an optional High Res DLC which requires the fan port.

[@Wyatt_James]

So basically what Id did with Doom and Quake. Decouple the engine from the assets, release the engine under opensource later.

[@SockyNoob]

I wish more old games had their source code released tbh.

[@Matanumi]

Its also not possible with more advanced games

[@Wyatt_James]

@@Matanumi Sure it is.

[@pearz420]

Those assets are really all they have. Companies sell assets when they go bankrupt.

So cool! There is a huge fan base for emulation and Zelda. I'm sure one of these awesome community members will have interest in porting on Android 😁

[@RadikAlice]

Heeeeyyyy, this is awesome! Big ups to the team! And thank you for covering it MVG

[@GiuseppeGaetanoSabatelli]

Seeing as there are just under 400 N64 games, I would find it interesting if we eventually decompiled and ported all of them before emulation got to a perfect state.

[@MrMoon-hy6pn]

I dunno if Hot Wheels Turbo Racing needs a decompilation

[@GiuseppeGaetanoSabatelli]

@@MrMoon-hy6pn Really? Game is lit.

[@handle.setUsername]

It took oot 2 years to be decompiled. I doubt anybody is gonna decompile random unpopular games.

[@diegog1853]

Hope this awesome work eventually leads to a (hopefully) much easir decompilation of majoras mask, so we can have the ultimate pc ports for both games, and with the already available awesome texture packs that they have, this could look breath taking.

[@gradearawk]

[@DeusGladiorum]

9:15 someone at Nintendo manually wrote line breaks for each dialogue box in the game? Bruhhhh

[@DeusGladiorum]

@@ANJK-eu7xf I know, right? I wonder why they didn’t have a function compute line breaks at runtime. Aside from the manual route being tedious, I’d also imagine it’d take up way more memory compared to a function, and I’d also imagine memory was really limited back in the N64 times

[@DeusGladiorum]

@Lukas von das Eis Just crazy to see compared to today when all software/games are built to be ongoing services. Probably made it both very freeing and very confusing when every aspect of our code didn’t need to be these well-defined, reusable components

This project is NOT cleanroom. If you view commit 6136ee6debd570a63fc695a6f4664553303f2324, and navigate to include/PR, you will find SDK header files from a leak some years back. While the work they have done is really impressive, it cannot be called cleanroom. All of the other N64 decompilation projects use these headers too, unfortunately.

So I wonder if this will make it possible to institute the open world system that was originally going to be in the game. Getting rid of the specific loading routines and making the game stream the data the way Windwaker does. That and cutscene skips would be nice.

[@KopperNeoman]

No need for data streaming unless you're running insanely HD models, textures, and sounds. Just load the whole thing in one go and be done with it.

[@VulpesHilarianus]

@@KopperNeoman Well that's the thing. Once the data streaming's in place, it opens up the game for better implementation of those things. I for one would really like real HD models, instead of the weird bad plastic mould looking ones from the 3DS ports.
