    Homebrew Unofficial 3DS RetroArch builds

    It's been a long time since I last tried it, but I seem to remember that Threaded Video caused performance drops and bad video pacing in some cores, even though it made a big difference in pcsx_rearmed. Threaded features also caused deadlocks on the old 3ds, I think because it could only spawn a...

    pcsx_rearmed is all software-rendered on 3ds. I was able to get some speedup on lighting/blending a while ago by dropping to assembly and avoiding some redundant instructions: https://github.com/libretro/pcsx_rearmed/pull/397 There might be more performance improvements to do there, but it...

    Yep, everything's good! A lot of my original motivation for working on this stuff comes from wanting to play a game that's not working well. I just haven't been playing a lot recently.

    If I remember correctly, core 2 is mostly reserved for the system, but user apps can create a single thread on it. When I tried using the system core for the rendering thread on New 3DS (so I could have 3 cores running code), it seemed to compete with the kernel for time and slowed everything...

    I’m not too surprised it crashes — I think I ran into something like that a while ago. It was something like the main core of the 3ds will only allow a certain number of threads to run at once. Since CD Access Async is also threaded, it makes sense that would crash too. Even if it could run, I...

    Nice!! When I was pinging the idea around in my head, I was thinking that it might be easiest to hook into the overlay system and display custom overlays on the bottom screen. They could provide extra buttons, hook into save / load state, etc. It might also allow less-technical people to...

    I spent most of the last month working my way through Dragon Quest XI, so... not really :-) I did add auto-frameskip to snes9x 2010 (https://github.com/libretro/snes9x2010/pull/139) -- you'd usually still want to use a 2005 core, but this at least makes some games playable that don't work in...

    I just grabbed the latest nightly build -- this is great! It's going to be a totally different experience having a bunch of cores available, but just installing / updating the ones you actually use.

    It's possible, but has not been done. I always thought it would be cool if you could use both screens for vertical games, or add a couple virtual buttons to the bottom screen, or even a soft keyboard. Since it would only be valuable for 3ds, though, I don't think it's had much attention. Just...

    Oh, I wonder if the old buildbot got turned off. May have to wait until they start building again.

    No idea, unfortunately. I never got into mame.

    Maybe, I haven’t looked into what it would take yet.

    Wanted to call attention to this announcement: https://www.libretro.com/index.php/coming-soon-retroarch-for-opendingux-release-gcw-zerorg-350etc/ Because the list of improvements at the end _also_ mostly apply to the 3DS, and make a big difference. Auto-frameskip is especially a great...

    I did see that, and yeah, I don't think it'll work on 3DS. It may work on very small games. I think he's talking about something similar to what I'm doing with the Async CD access. It would actually be nice to get that into libchdr -- that way, we'd be able to use it in Sega CD / TG16-CD, etc...

    Thanks for letting me know! This should be fixed in the next nightlies.
