# Handheld streaming and homebrew — Artemis-Switch, moonlight-N3DS, sm64coopdx-switch

> PC game streaming on Nintendo Switch with Artemis (Apollo/Sunshine), Moonlight on New 3DS, and a Switch port of sm64coopdx — three homebrew repos and what each one does.

- Author: Antoine Boucher (https://antoineboucher.info/CV/index-en.html)Three repos I maintain on the side: **[Artemis-Switch](https://github.com/antoinebou12/Artemis-Switch)** for Apollo/Sunshine streaming on Switch, **[moonlight-N3DS](https://github.com/antoinebou12/moonlight-N3DS)** for GameStream on New 3DS, and **[sm64coopdx-switch](https://github.com/antoinebou12/sm64coopdx-switch)** as a Switch build of cooperative Super Mario 64. They share the same itch — run something interesting on hardware that was not designed for it — but the stack and constraints differ.

## Artemis-Switch — PC streaming on Switch

[Artemis-Switch](https://github.com/antoinebou12/Artemis-Switch) is my fork of [XITRIX/Moonlight-Switch](https://github.com/XITRIX/Moonlight-Switch), wired for **Apollo** (Sunshine) hosts instead of classic NVIDIA GameStream. I stream Steam Big Picture from my desktop (`AntoinePC`) and use the in-app overlay for quick host shortcuts and a live performance panel.

![Artemis quick menu — host shortcuts and keyboard presets while streaming Steam Big Picture](https://antoineboucher.info/CV/blog/posts/handheld-streaming-homebrew/images/artemis-quick-menu.png)

The **Quick** tab exposes window-management shortcuts (`Win+Shift+Left` / `Right`), keyboard presets, and Apollo host scripts without leaving the stream. Handy when the host is a Windows box and the Switch is just the display.

**Performance** shows bitrate (~12 Mbps in this capture), Switch Wi-Fi bars, and receive / decode / render timings. Render is usually the bottleneck on Switch; sub-millisecond receive and decode means the network and decoder are healthy and the frame budget is mostly compositing.

Repo: **[github.com/antoinebou12/Artemis-Switch](https://github.com/antoinebou12/Artemis-Switch)** (★ 12). Upstream Moonlight-Switch work also shows up on my CV as [merged toolchain fixes](https://github.com/XITRIX/Moonlight-Switch) for newer devkitPro toolchains — separate from the Artemis fork, same Moonlight lineage.

## moonlight-N3DS — GameStream on New 3DS

[moonlight-N3DS](https://github.com/antoinebou12/moonlight-N3DS) tracks [zoeyjodon/moonlight-N3DS](https://github.com/zoeyjodon/moonlight-N3DS), a GameStream client for **New 3DS** (extra RAM and CPU vs OG 3DS). My fork is where I experiment with build fixes and integration; star count on **my** repo is still low — the community interest lives on upstream (~300★), which is the right place to look for installs and issues.

Constraints are brutal: 400×240 top screen, software decode, Wi-Fi on a 2015 handheld. Expect lower bitrate and higher latency than Switch; the win is having *any* Moonlight path on 3DS at all.

## sm64coopdx-switch — co-op Mario 64 on Switch

[sm64coopdx-switch](https://github.com/antoinebou12/sm64coopdx-switch) ports [coop-deluxe/sm64coopdx](https://github.com/coop-deluxe/sm64coopdx) to Switch homebrew. sm64coopdx is the continuation of sm64ex-coop: online co-op, Lua mods, and QoL the decomp scene added over years.

**Legal note:** like every SM64 port, you must supply your own **legally obtained ROM**. The repo builds the port; it does not ship game assets.
