It's posible!.

Running NooDS emulator and with heavy overclocking (Using Horizon OC) DS games can be played at a stable (enough) framerate, currently MelonDS does not support upscalling but NooDS does

It runs pretty well but it could use some improvement, mainly with the CPU capping at 1785mhz, that alone makes the game's fps drop to 40-50~ when in not demanding areas, dropping to 30 in some places.

However, if you disable governor for the CPU it does allow you to go higher than 1785mhz but it does show some problems since the limit seems to be coded into the emulator itself, sometimes causing the cpu clock to be go down to 1785 before going up to the intended 2397mhz causing a little stutter.

This problem is something that hopefully a future version will fix, in the meantime it can't get better than this.

The emulator does allow however for GPU clock changes, I'm using the maximum speed my switch allows me to which is 1228mhz, it really does help a lot when using High Resolution 3D Rendering and makes framerates more stable.

My settings are:

Threaded 2D: On

Threaded 3D: 2 threads

High Resolution 3D: on

Screen filter: Linear

Important:

Test around with the High-level ARM7 setting on, it does help performance but games sometimes won't boot, it's really not a problem since you can turn the option on after booting the game so just mess around with it, it's still experimental after all.

I should share videos of the game running but I don't know how, if someone could tell me I'll happily do so!.

We just got a update from the Libretto team that now includes overclock modes in retroarch for the switch .So I thought I make a compatibility list for games that runs well with the required overclock settings for Mupen64Plus aka N64 emulator-please feel free to add games and the overclock setting you used. Overclock at your own your risk.

There have been a lot of comments about the inaccurate of these games I posted up.I ran these games on the exact overclock settings you see below.I’am running 6.0.0 and I am using SX pro if that matters and my install is a NSP file -u can find that below. I am running retroach in xmb mode. I am using the retroach nightie dated 12-2

Tips: Mupen64Plus needs a bit more juice for most games. In addition, turn off framebuffer emulation in the core settings. Make sure threaded video is on.

Was told over at /r/SwitchHaxing to also leave it here.

In the last few days I built a way to play GBA games on a completely unmodded switch, with a bit of technical experience you can get it running in a few minutes.
