L4T Lakka Switch - now with audio and Vulkan

logonav.png

Lakka Switch, L4T edition
I am proud to finally release the L4T version of Lakka Switch!
New kernel, new logo, new drivers, audio... everything is fresh and clean.

Did I mention Rayman 3 was full speed on Dolphin? ( ͡° ͜ʖ ͡°)

General system updates
  • New Linux kernel and underlying operating system, based on Linux4Tegra and Jetson Nano drivers
    • mainline kernel has been deprecated
    • system features should now be on par with the L4T Ubuntu distribution, except for dock support
    • Bluetooth was lost in the battle and needs some rest to come back stronger
  • aarch64 is now the default and mainly supported architecture
    • arm has been deprecated since L4T doesn't support it
  • New logo made with the help of jaames and the R:S community
New features and improvements
  • Audio now works through the internal speakers and headphones
  • The new GPU driver supports both Vulkan and OpenGL
  • RAM is now locked at full speed (1600Mhz), was 800MHz before
  • The system is now way more stable and should boot for everyone with a decent SD card (no more black screen of death)
  • RetroArch has been updated to add menu widgets (fancy onscreen notifications)
  • Overclock profiles have been updated :
    • Renamed all profiles
    • Added more overclock profiles
    • Added underclock profiles
New cores
  • mupen64plus-next (N64 emulator)
    • The core is full speed, even on aarch64 thanks to the new dynarec
    • Includes the updated version of the GlideN renderer
  • picodrive (various Sega consoles)
    • The core replaces Genesis Plus GX (Game Gear support has been dropped)
  • Beetle PSX HW (PSX emulator with OpenGL and Vulkan renderer)
    • The core performs worse than PCSX ReARMed for now, even with Vulkan
  • reicast (Dreamcast emulator)
    • The core is full speed on all commercial games, no visual glitches
    • The OIT renderer works (better accuracy), speed is still good on 1x resolution
    • The core needs the Dreamcast BIOS files to be placed in /lakka/storage/system/DC
    • WinCE games are currently not supported - there is a WinCE version of the reicast core in the works but the aarch64 dynarec is too slow for the games to be playable (for now)
  • Yaba Sanshiro (Saturn emulator)
    • The core is full speed on all commercial games
    • Yabause and Kronos were also added but both perform worse than Yaba Sanshiro
  • theodore (Thomson MO/TO emulator)
Updated cores
  • Dolphin : Vulkan support
    • With Vulkan, Dolphin runs decently - some games are playable, some are full speed... see for yourself, try it and experiment with different games and settings!
  • PCSX ReARMed : Switch optimizations and CHD support
  • PPSSPP : doesn't crash anymore when closing content
Removed cores
  • mupen64plus
  • parallel-n64
  • Genesis Plus GX
  • Ishiiruka
    • It might come back once the core is updated with the (beta) Vulkan renderer

Well, for my Switch running L4T 1.3 (1.3.1 wasn't released when I went to bed), it was at 81% when I put it in standby. When I got up (about 5, maybe 5.5 hours later), it was at 41%. I'll be trying 1.3.1 tonight. Hopefully 1.3.1 has less dropoff than that (seems like it'd last less than a day to me, based on a 40% battery loss in 5-5.5 hours).

--------------------- MERGED ---------------------------

FWIW I'm pretty sure you'd also have no sound, because that's all drivers that are tied in together... unless you are okay with BT audio.

In which case, you can use the previous Lakka build, which supported only wireless joycons :)
Except that the old version couldn't run Gamecube games. The L4T based Lakka has significant speed and efficiency improvements.

As for audio, I bought a bluetooth speaker specifically for Lakka, so no, bluetooth only audio doesn't bother me. However, more importantly, if that were true, then audio would be broken in either L4T or Lakka. Since it's working in both (and bluetooth isn't), I can't see it being likely that implementing bluetooth (and losing wired joy-cons) would break audio.

I have some inside knowledge of when its released :) June 15th from what I heard
Well better then nothing I guess. Hope its sooner but hey lakka has improved so much already I can wait a few weeks. Hell even months at this point. Ape escape with no issues is worth it alone.

Can I ask though (to anyone who may know) how S2idle compares to horizons sleep mode? Will battery drainage be much different? Can it be left in its sleep/suspended mode for days as done in Horizon?




Hope this helps ;)

Ya same settings i use :P 60%, I think aswell(although haven't tested too thoroughly) you can get a smoother performance if you hold B on startup(sometimes you need to keep mashing it) and change from 60Hz option to NO(At nintendo logo). Game runs more smoothly at 50Hz. I use Threaded Video in the settings also.
I have a feeling the dolphin emulator version itself plays a part in the performance too(specially audio), I seem to be able to up the EFB scale to 2X(much nicer resolution) with the above settings and the game in the opening village runs almost perfectly, with just occassional audio stutters.
this worked wonders!! thanks dude

Wish I could get this to work, but all I get is a blackscreen or if it does boot up it freezes on menu :/
So I managed to get it to work 2 different ways but both in the end what made the difference seems to be the partition table type (note that I am on Ubuntu).

- The easiest but longest is to write the L4T Ubuntu image on your card, deleting the ext4 partition, extending the fat32 partition, deleting all files on the fat32 partition and then copying lakka the same way you would usually do (do not forget hekate).

OR

- Download GParted, delete all existing partitions on your sd card then create a msdos partition table type, then create a fat32 partition.

For some reason by just doing that it worked on all my sd cards where it was not working previously! Hopefully it will help someone else!

Did you try that? Worked for me and a couple others here!
