Intel laptops and handhelds, finally first-class: the open-source Nintendo Switch 2 emulator tuned for the integrated GPU you actually have.
A fork of Lichii (the yuzu, Eden, Eglantine line), GPL-3.0-or-later, built to be easy to contribute to, with or without an AI agent.

No keys, firmware or games included: bring your own, dumped from hardware you own. Not affiliated with Nintendo. Legal.
The proof: on a Core Ultra 9 285H laptop with an Arc 140T iGPU, one shader fix took Ocarina of Time's Hyrule Field from 14.8 to 22.8 game fps with frame generation off (the table). Every number names its machine.
Play Ocarina of Time on your PC
- Play it on a PC or laptop: download, bring your own keys, firmware and game, switch on frame generation. The 5-minute path, with the Intel Arc settings on one page.
- Best emulator, or a recompilation? The emulator runs the game as you dumped it; a recompilation is a separate native port per game. How to choose, including Lichii, Eden and Eglantine.
- Stutter, black screen, crash: a first-visit hitch is shader compilation; uneven motion is pacing. What helps, with numbers.
- ROG Ally, Legion Go, MSI Claw, Steam Deck: none measured by us yet. What to expect and how to send a device report.
- Controllers (Xbox, DualSense, Switch Pro, 8BitDo): setup.
Most Switch emulators are tuned on big graphics cards. Guarana is tuned on the chip most people actually have:
the GPU inside a laptop or handheld, which shares memory and a power budget with the CPU. It aims at
even frame pacing (steady frame times, not only a higher average) and at frame generation that fits an
iGPU's power budget. Intel Arc integrated GPUs get measured data and an Intel-specific preset here, and frame extrapolation
(frame generation without the latency interpolation adds) is opt-in and so far measured on one machine. Every number below names the machine it came
from, and a change ships only with a paired A/B on a verified scene (the rules).
Measured wins
Test device: Core Ultra 9 285H, Arc 140T iGPU, Intel driver 32.0.101.9175, 120 Hz OLED, 32 GB RAM, plugged in.
Game: The Legend of Zelda: Ocarina of Time, unless the row says otherwise. Game fps counts frames the game
renders; generated frames are not included.
| Win | Before | After | Status |
|---|
Hyrule Field, from one shader fix (EDEN_NX2_GM=11) | 14.8 game fps | 22.8 game fps | In v20; on by default for Ocarina of Time only |
| Foliage mesh draw, same runs | 15.7 ms GPU | 5.8 ms GPU | In v20 |
| Frame generation pacing, title screen: frames whose interval is within 2 ms of the median | n/a | 100% (16.7 ms pacing) | In v20.1, opt-in (EDEN_NX2_FLUID=1) |
| Same measure, Hyrule Field | 33-54% | 75% (p5 16.4 ms) | In v20.1, opt-in (EDEN_NX2_FLUID=1) |
| Headless shader warm-up | n/a | 4,515 pipelines in 155 s | In v20.1 (eden-cli --warm-pipelines) |
| What changed | Before | After | How it was measured |
|---|
EDEN_NX2_GM off → =11, frame generation off | 14.75 game fps | 22.83 game fps | Hyrule Field overlook, same spot, switch on vs off |
| GPU time of the foliage mesh draw, same runs | 15.7 ms | 5.8 ms | Same spot, switch on vs off |
| Play config (frame generation 3x toward 60): earlier unreleased build → v20 | 19.6 game fps, locked at 50 ms frames | 26.7 game fps in Castle Town, 28 in the field | Live readings, not a same-spot A/B |
The pacing rows come from EDEN_NX2_SHOWN_STATS, which reports every 10 s how evenly frames reached the swapchain,
generated ones included (docs/switches.md). The pacing work behind them is described in
ROADMAP N1 and shipped in v20.1.
No figure for input latency is published yet, because none has been taken the same way.
