Hey everyone! 
After months of work, testing, and a few sleepless nights, I’m proud to present a new version of my Dolphin project for muOS. This isn’t just an update of the old core — it’s a complete rewrite that takes the best of what came before and pushes it to a new level.
This is
DOLPHIN RT:CORE for muOS - v11.5.00 ‘Triptych’
and this is Flavour I: Comfort Zone.
What is Comfort Zone?
Comfort Zone is the streamlined edition of Dolphin Rt:Core. The idea is simple: no useless menus, no settings to fiddle with, no bloat. You assign the core to your ROM folder, pick a profile, and play.
Everything happens through the muOS Content Explorer, exactly like any other emulator in the system.
Finally — A Working Exit Hotkey!
Let’s start with the headline news, because this one deserves it.
Comfort Zone finally ships with a working exit hotkey: START + SELECT.
You press it, Dolphin quits, you’re back in muOS. No more rebooting the device.
For anyone who has spent time with GameCube or Wii emulation on these handhelds, you know exactly how painful this was. You finish a session, you want to try a different Profile, or you want to test another title — and the only way out was to reboot the entire device. Every single time.
Thankfully muOS has extremely fast boot times, otherwise this would have been an absolute nightmare. But even with fast boots, it was a real gap in the experience — and it was felt. Now it’s gone.
The exit is clean:
-
START + SELECTsends a properSIGTERMto Dolphin -
The launcher catches the signal and shuts everything down gracefully
-
You’re back in the muOS frontend in under two seconds
No menus. No overlays to dismiss. No combos to memorize. Just press and you’re out.
What’s Included
Seven Ready-to-Use Profiles
Every profile is tuned for the H700, with JITARM64 forced (CPUCore = 4) and async shader compilation (ShaderCompilationMode = 3). Compared to the previous version, CPU-bound performance improved by 50% to 300%.
| Profile | Description |
|---|---|
| performance | Daily driver, balanced |
| compatibility | Accuracy first, slower |
| rintromping | Maximum speed |
| speedhacks | Extra hack flags enabled |
| blackscreenfix | For games that won’t boot |
| sweetspot | Custom-tuned balance |
| default | Baseline reference |
Available for GameCube (upright) and Wii (upright + sideways).
Automatic Bloom Removal
The “All Games Bloom Removal” mod is always active for every game. It’s the single biggest FPS gain on H700 (+2–5 FPS on most 3D titles). Zero configuration needed.
Per-Game DOF Removal
For the heaviest titles, we’ve added Depth of Field removal — already active and targeted only to those games:
Crash Nitro Kart · Crash Tag Team Racing · Crash: Wrath of Cortex · DBZ Budokai 1/2 · Super Mario Sunshine · Scaler · Metroid Prime · Super Smash Bros. Melee · Mario Smash Football
Curated GameSettings
12 per-game overrides for problematic titles (NFS Most Wanted, Crash, DBZ, Mario Sunshine, etc.), each documented with region, reason, and expected FPS.

Usage
-
From muOS, open the Content Explorer
-
Navigate to your GameCube or Wii ROM folder
-
Press X → Assign Core
-
Select Nintendo GameCube or Nintendo Wii
-
Pick a profile from the list (7 available)
-
Launch any game — the core is now assigned to that folder
Compatibility List
The community-curated compatibility list with 200+ tested titles is available here:
silvercrow2323.github.io/Dolphin-Core-for-MuOS
Each entry includes: star rating, FPS range, recommended profile, and known issues.
Honest Note on Performance
The H700 is not hardware for Dolphin. This is a technical demonstration, not a plug-and-play emulator. Realistic expectations:
-
Lightweight 2D games: 30–50 FPS -
Medium 3D games: 15–25 FPS -
Heavy 3D games (NFS, Crash, Zelda): 5–15 FPS
If you want smooth GameCube performance, you need a device with Snapdragon 8 Gen 2 or better. But if you want to squeeze every last drop out of the H700, this is the closest you’ll get.
We Want Your Feedback
This project lives and dies by community testing. If you try Comfort Zone, please share your results — whether they’re good, bad, or ugly.
Specifically, we’d love to receive:
-
Test results — which titles work, which don’t, and at what FPS
-
Winning configurations — profile + GameSettings combos that made a game playable -
Useful mods — any Graphics Mods or texture packs that improved a specific title
-
Sources and links — Dolphin forum threads, community spreadsheets, anything useful
-
Bug reports — if something breaks, tell us exactly what happened
Post them in this thread, or open an issue on GitHub:
github.com/SilverCrow2323/Dolphin-Core-for-MuOS/issues
Every report helps. Every config gets folded back into the next release. This is a community project, and the community makes it better.
