To everyone still having problems with PSP games, use this RetroArch package and the PSP core that I've attached.

It works perfectly with firmware 21.1.0 and Atmos 1.10.1.

Place your ppsspp_libreto_libnx.nro core it in the file path like so


RetroArch\cores\ppsspp_libretro_libnx.nro


set your Retroarchswitch.nro in the switch folder like so


switch\RetroArch_switch.nro


Then last but not least set your RetroArch folder to the root of you sd card!

Where did this core come from?

Is it possible for some to do the ship of Harkinian?

OOT ship of Harkinian has already been don if you take some time to read the thread you will find it or search for it in the github Harbour Masters. I just updated to libnx v4.10.0 I shall try and recompile MM 2ship after i get some sleep..... most annoying thing is having the artifacts expired but i have it backed up on my old computer

I will not provide any information about that. Why do you want to know?

Because GPLv2 license should allow us to review the source it was created from. In turn, why are you unwilling to provide those details and making it feel a touch sketchy?

Look at page 1 Retroarch: MODDED by drizztbsd for FW 21.0.0

That's the PPSSPP file I got it from.

It seems the scene is mostly dead (understandably since you can get most things through L4T Ubuntu anyway) but I've been considering downgrading to 1.9.5 to avoid the mess of waiting for further updates.

But if I do this, will updated .nro's work with the downgraded firmware? If it's a non-issue I'm just gonna do it.

How's L4T running for you? I have LineageOS (latest build) on my Lite and the performance is absolutely terrible. Like even GBA emulation is lagging. I even have the ram OC'd, mSD optimizations on, and the option for the lower Mariko voltage on. It's still decent for web browsing and video playback but everything else is pretty abysmal.

Haven't tried GBA but I was playing the first 3 hours of Twilight Princess on Dolphin and it's 100% speed 90% of the time without downgrading any settings.

I use Kubuntu Noble. I think it gives slightly more headroom than Ubuntu. It can also play many parts of KH1 on AetherSX2 at high speeds, and play certain PC games downloaded over GOG through Wine.

Again, I haven't tried GBA. Maybe it's just bad. I wouldn't use Retroarch with it, personally. Dedicated emulator builds for Arm64 seem to be the way to go. But I want to stop relying on Ubuntu because at least when emulating PS2 the console powers off with "OC All" at random times. I have a V1 Switch so maybe that's why but it makes the console fully unportable because I'd have to reinject Hekate.

Well if GC runs decently GBA sure would. Although the OC options are way more limited on the Lite due to heat and battery limitations. But GBA really doesn't need particularly fast hardware. It's pretty baffling that it manages to lag on Lineage no matter which emulator you're using.

 

[Esurient]

I will not provide any information about that. Why do you want to know?

To know where to go for future updates?

Also because this version matches exactly with the buildbot core, which makes me question, how exactly is this modded?

Hello Team,

First of all, I want to thank all the people who shared the adapted homebrew apps versions to make them work under FW 21.1.0 and AMS 1.10.1

Secondly, I just wanted to share that I managed to make all this stuff work under the already mentioned FW 21.1.0 and AMS 1.10.1 (thanks to all of you ):

OVL Suff:
emuiibo.ovl
ovlEdiZon.ovl
ovlmenu.ovl
ovlSysmodules.ovl
Status-Monitor-Overlay.ovl
sys-clk-overlay.ovl
sys-patch-overlay.ovl

Homebrew Stuff:
aio-switch-updater
AmiiboGenerator
appstore
Awoo-Installer
botw-unexplored
daybreak
DBI

Goldleaf
haze
JKSV
Linkalho
melonds
nx-titles-list-dumper

retroarch_switch
soh (with HD textures, really cool)
sphaira
switch-cheats-updater
switch-time
Switch_90DNS_tester
sys-clk-manager
totk-unexplored
tinfoil (it starts but gives an error at exit and stores won't download anything).

Retroarch Cores:
All, including these ones: flycast_libretro_libnx.nro and ppsspp_libretro_libnx.nro, which gave me some problems, except the following one:
-> citra_libretro_libnx.nro

Does anyone know whether any development or updates are being performed regarding the RetroArch citra_libretro_libnx.nro core for Nintendo Switch FW 21.1.0 and AMS 1.10.1 onwards? I have been told something about a Patreon under which someone is making some developments.

The previous version of citra_libretro_libnx.nro worked well enough with the games I wanted, and that is what I want to recover.

Could someone share that mentioned Patreon URL??

Thanks in advance,

Best regards,
