F-Zero X on Nintendo 3DS(hypnotize.works)

    I’m curious why people have started using the 3DS as the gateway device for ports of games, like Melee and F-Zero X.

    Don’t get me wrong, the 3DS is a gem of a console, and it harks back to when Nintendo put more thought into what they released instead of just another Mario sports game; but since the Switch is so much more powerful, I’d expect ports to that be more of a priority.

      Not sure why others are doing it, but the switch is kind of a boring console imo. You may as well just use one of the million PC handhelds with the same form factor, and persistent hacks require a hardware mod.

      The 3DS is a fun pocketable form factor which a lot of people already own and easy to permanently mod on any firmware version or hardware revision.

        I'm surprised no one has mentioned online: most people don't want to risk console bans, and that immediately makes jailbreaking their Switch a non-starter

        At this point most people getting a 3DS are probably doing so specifically to jailbreak it

    • coffeesoda3 hours ago
      The 3DS has the novelty of 3D. I always wanted to play F-Zero in this form factor and it seemed like a reasonable port to accomplish.

      I would guess the 3DS is far more "jailbroken" than the switch.
      • prophesi3 hours ago
        Jailbroken 3DS scene is usually for modding the console OS itself given how easy it is to run custom firmware. And for ports, and emulation. While the GBA has a pretty dedicated community for custom games and romhacks, people often create games for the platform at gamejams because of how great the dev tooling is. It's a bit lackluster on the 3DS, but I did find the Love Brew[0] framework to be really nice. Even has simulator support[1] for testing your builds locally, though fonts will look much different on real hardware, with likely a bunch of other gotchas. Running out of RAM being a big one.

        edit: compared it to the GBA homebrew scene since it's a large dedicated community to derive pros and cons between the two from. Switch is still receiving updates from Nintendo to brick your system.

      • tourmalinetaco3 hours ago
        It is. Any 3DS can be jailbroken with CFW with a simple Internet guide and no physical modifications. As far as I know, the Switch CFW is locked to only V1 motherboards or modchips, making it far less accessible even if it is more powerful.

      The N64 dev scene seems to be taking off too. If I had to guess, working around limitations in hardware are the fun part for a lot of people.

    Hey, author of the project here! Thanks for posting! It's been a really fun project to work on, and a great way to learn about how to use Claude more efficiently. I'm just a few hours away from posting a big update with:

    64dd on original 3DS

    Local & Online Multiplayer

    QR Code sharing for Custom Courses

    I hope ya'll check out the authors notes, post-morterm, and give it a try on your 3DS.

      Look, I'm gonna say what's been said a lot of times, but bears repeating: when the very first two or three sentences I read are mind-blanketing AI prose breathlessly em-dashing together fragments of stuff I don't care about, it makes me skeptical that there's value perusing the rest of the project. Like, you can't even be bothered to make your lede some form of human-to-human communication.
      • ryan_n3 hours ago
        In the "Read On" section at the bottom it says "Author's notes: The one page written by a human." Seems they're pretty open about everything being written with Claude.

        Get used to it. This is the future. It's okay.
        • CursedSilicon2 hours ago
          I wonder how long it'll take people like you breathlessly chanting "this is the future!" before the slop bots hoover that up into their training data like narcissistic poison

          Tell the slop bot it's wrong about something and it just starts berating you "get used to it!" "I'm the future!"

          All your stuff is vibecoded these days? Or is this a general complaint about negativity in the comments?
      • coffeesoda3 hours ago
        Appreciate it, but the info is there for anyone (or their LLM) to learn about the project in a technical sense. Like others have kindly stated, my notes (written by a human, for humans) are in a separate section.

        The technical notes are dense and interesting in their own right, but I don't expect anyone not already familiar with the N64 to 3DS port scene to care.

    • aculver4 hours ago
      Haven't had a chance to check the project out yet, but wanted to say I love the idea of having a section dedicated to your human-written thoughts. It's the best of both worlds, with as much detail as possible throughout, but also still getting to hear from you personally. Congrats!
      • coffeesoda3 hours ago
        Thanks! As fun as the project is, the scope of it is not lost on me. I wanted it to serve as evidence of the frightening power these recent models have, and make it clear.

    The costings here are based on API pricing, but my understanding is that no one is paying the API pricing and everyone uses the subscription pricing, or even multiple accounts with a subscription each. I'd be interested to know the actual cost incurred here.
    • Yahivinan hour ago
      I’ve found that subscription is ~98% cheaper than API pricing.
    • ivraatiems3 hours ago
      I think the API pricing is a good proxy for "what was the actual physical cost of doing this," but even if you increase it from 5k to 30k or even 100k, it's a huge savings over getting a human to do it, AND it was faster.

      I don't think the productivity gains from AI can be ignored for contexts like this. It's what they're best at.

      I just hope it goes to good uses (more ports of fun games, more interoperability and opennesS) instead of bad ones (firing humans instead of retasking them), and that hope feels faint.

      • Gigachad3 hours ago
        In no way am I suggesting that doing this without AI would be more practical. What I want to know is roughly how much is Anthropic subsidizing this stuff through the subscriptions currently and how much we can expect the real price paid to go up in the future.

      • coffeesoda3 hours ago
        Yep, I agree. Further in the notes it's mentioned this probably would've taken a handful of Senior Engineers anywhere from 6 months to 2 years. The range of budget on the project is like $200 to $500k. This was done for peanuts in my spare time. I share both your optimism and pessimism, depending on the day, lol.

          > This was done for peanuts

          If you don't have a real dollar cost then can you tell us how much it actually cost in peanuts?

      • bakugo3 hours ago
        > it's a huge savings over getting a human to do it

        This of course assumes it's something anyone would consider worth paying a human to do (it's not).

          It was, 15+ years ago, when porting N64 games to 3DS was a lucrative market for hired guns. We have the magic 'port' button and this tech just showed how easy it is with severely different architectures & constraints.
  • kingofspainan hour ago
    Well this is interesting to see. I was thinking of porting my game to 3DS which is based on my memories of playing F-Zero X (mainly trying to make it as fast as possible!)

    Now I’ll have to do it and see how they compare. I purposefully avoided playing it again during development so it’ll be most curious.

  • matthewfcarlson2 hours ago
    I’m almost done with a port of two games from the original Xbox to modern platforms. While having a good background in assembly and understand of why x87 is problematic and SSE makes life a little easier to understand what it’s doing. And I’ve offered a few suggestions that I thought were useful but it’s been shockingly hands off
  • sara_kumodeck2 hours ago
    how are u planning to handle netcode for online muktiplayer on the 3ds?
    • coffeesodaan hour ago
      It's already done. The race sim is fully deterministic so the consoles exchange controller inputs and run off the same seed. It uses the underlying VS. mode for the scaffolding but changes the screen render to full for each player.
  • peggigulgow3 hours ago
    The 3DS fillrate budget is the interesting constraint here. F-Zero X was already doing a lot with the N64 T&L pipeline; mapping that onto a tiled GPU without dropping the 60fps target is the part I'd want more numbers on.
    • coffeesodaan hour ago
      Good instinct, the bottleneck is on the CPU side though. The PICA200 is an immediate-mode GPU not a tiler.

      Other F-Zero X ports feed the N64 display lists to an interpreter, command by command, with the T&L on CPU. Pre-v1.0 of this port took that approach but did some double buffering on another CPU core.

      When porting to Old 3DS, that other core wasn't an option, so we had to make better batch calls to the GPU. It ended up being that now we walk that list the first time and group triangles that share the same material, and moved the position & rotation transformations to the GPU too.

      Rather than creating the mesh for tracks out of the spline on the fly, it also precomputes at the start of the race.

      I'm fairly certain this is a pretty novel implementation for a N64 to 3DS port.

      Most of these optimizations are just for race elements, which is why some of the menus are still pretty laggy.

    I wonder how many years it would take to slopport every ROM-available game on every viable piece of hardware /s
    • pizzathyme3 hours ago
      we are going to find out very soon
    • echelon3 hours ago
      > slopport

      Screw that word.

      This took effort.

      I don't want to share the internet with this bombastic negativity.

      I wish anti-AI folks would find usenet or something and leave us to reinventing the web back into a magical place.

      This is the Web 1.0 Wild West again. And it's beautiful.

      • opan28 minutes ago
        Is there a reason you've decided the current Web belongs to the pro-AI crowd? Why can't they start their own community of only AI lovers and leave the Web as it was? I hear lobste.rs has changed course on their AI stance, removing the relevant tags and deleting anti-AI comments recently. Compared to HN then I would think lobste.rs is like a safe haven for AI projects.

        I am doing a lot of LLM writing and porting; and am still calling it slop. Even though it saves me a bunch of time at work and in hobby coding.

        Not sure why online forums attract this kind of permanently grumpy person whose only contributions are complaints and nitpicks and snark, but I’m happy to shame, downvote, and flag them every time.
        • woozlewuzzle2 hours ago
          I've noticed social media in general tends to be filled with posts by people like this.

          I'm guessing well-adjusted level headed people are off doing more productive things.
