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

The Lakka Switch website has been updated with the new version: https://lakka-switch.github.io/documentation/

Please note that you can't dual boot Ubuntu and Lakka Switch for now (it will always boot Ubuntu).

Interestingly the synchronization section on audio settings was just completely removed. I guess it not working would explain why I can't get stable frame pacing on say Genesis or anything else.

Edit: also I forgot how to boot from Lakka straight back into hekate? The reboot option just starts Lakka again, the shutdown option goes into RCM mode. I have hekate rebooting itself already with a reboot_payload.bin in my root directory that is itself hekate.

to cancel hekate's auto boot, hold "minus" volume button when rebooting... also, that framepacing issue is not a lakka's problem iirc, it's nvidia's drivers that they have been promising to fix since long ago but never actually did

 

[bad361]

Has anyone tested if this Lakka version runs gamecube games with better performance?

you won't get any performance boost until lakka's dolphin core gets proper care, it's very far behind and need a lot of optimizations and updates compared to its standalone version

Auto boot is disabled. My issue is that when I'm done using Lakka, I want to exit directly back to Hekate. I thought I could do this in 3.0, maybe there was some setting that I've forgotten, or other place where reboot_payload.bin has to go. Right now it's in the root folder and hekate does correctly boot when choosing restart from within Atmosphere.

I could've sworn I had reboot to payload in a previous setup, but I just had to redo my SD card, installed 4.1 and now it just reboots Lakka. I guess I could be imagining things or confusing it with Android, which I was also using and definitely has reboot to Hekate, but I really don't think so.

What is happening is hekate's auto boot which boots you directly in lakka. Gavin made that change not long ago... Now everyone (me including, tho i guess i was the first one to ask) asks how to get to hekate during reboot instead of lakka. HOLD "vol -", it will cancel autoboot and you'll get to hekate. You can change that behavior back to how it was before by editing uenv.txt in lakka folder.

Thanks, I edited lakka/uenv.txt and changed "reboot_action=bootloader" and it works as expected now.

Well, reboot is (and always was) expected to just reboot lakka, not to launch some other payload . So now its considered as expected but whatever, i personally like the way it is now more.

hello there, what's the best settings to get fullspeed ?
I've turned vulkan but there's other settings to do?

depends on the core, but usually overclocking should suffice (if not, then probably there's not much you can do)

 

[wakabayashy]

saturn mostly, I've put "maximum performance", I've to do another thing?

 

[Andorin]

Hi there.
Can someone explain quickly what is Lakka ?
Can you tell me what is it useful for ? (Emulation I guess ? How good is it for emulation (PSX, Gamecube, etc...))

Thanks !

yeah, saturn struggles to run both in hos and in lakka..i don't use it myself, only tested sega rally some time ago, but iirc it needs vsync to be off (or on lol, i don't remember, something with vsync), and full oc of course. Sega rally was fullspeed

Google exists for such questions.. go to www.lakka.tv and read what it is. Performance wise, psx is perfect with swanstation, dolphin is usable but don't get your hopes up, a handful of games are truly fullspeed, most of the others need frameskip to be playable (many are unplayable at all). Pretty much anything up until gc can be emulated really well in lakka (excluding saturn i guess).

@bad361 Any chance of getting MMJ R ports of Dolphin on lakka?

I'm not a dev, i can't port shit, how could i know.

 

[wakabayashy]

how can I pair the pro controller?

 

[bad361]

how can I pair the pro controller?

just pair it in bluetooth settings in lakka, it should just work...get the controller into pairing mode and scan for devices in lakka

it's ok, thanks to you, it's paired

 

[knightowl]

Can't access quick menu with L3+R3 as of the new update

EDIT: Nevermind! Fixed by deleting retroarch.cfg from my setup and launching Lakka afterwards

 

[MG4M3R]

It's Just me, or is the docked mode broken on Lakka's last stable release?

Image keep flicking on screen like if it was changing modes every second
