Hey fam 👋
If you’ve ever booted up a Retroid Pocket 5, AYN Odin 2 Portal, or any Android-based handheld and thought, "Okay, now what?" — you’re not alone. Setting up your system to feel smooth and console-like can be confusing, especially when words like frontend and backend get thrown around.
So let’s demystify it all 👇
🤖 What’s a Backend?
Think of the backend as the engine under the hood. It’s the actual emulator or player that does the work of running your game. It doesn't care what it looks like — it just focuses on performance, accuracy, and features.
You don’t really “see” the backend unless you’re launching it directly. Most people don’t dig into its menus — they just use it to boot up a game.
🔧 Popular Backends – Pros, Cons & Why It Matters
Backends are the powerhouses of gaming on your handheld. These emulators are responsible for running your games, and the right backend makes a world of difference in performance and compatibility. Here’s a breakdown of some popular backend options:

🎨 What’s a Frontend?
Now the frontend is what you see. It’s the user interface — the menu system, artwork, game lists, console logos, and smooth transitions. The frontend helps make your device feel like a proper console rather than a messy folder of apps.
You use the frontend to browse your games, choose systems, and maybe even scrape box art or trailers.
🎮 Popular Frontends – Pros, Cons & Setup
Let’s break down the top frontends and why you might (or might not) want to use them:

✅ Pegasus Frontend

🧩 How They Work Together
You don’t have to choose just one — in fact, you’re supposed to use both.
For example:
You open ES-DE (frontend) and scroll through your gorgeous library of games.
You pick a PS2 title.
ES-DE silently launches AetherSX2 (backend) behind the scenes to play the game.
This makes your handheld feel like a plug-and-play console. Just power it on and go straight into gaming, no menus, no apps, no confusion.
🌟 Why the Frontend Experience Matters
Here’s the thing — the frontend is what most people interact with. If it's confusing, slow, or ugly, it makes the whole experience feel frustrating, no matter how good the emulator (backend) is.
RetroArch is a good example: it's an incredibly powerful tool (supports shaders, save states, achievements, multiplayer, and more), but its menu system — especially for newcomers — feels like a maze.
That’s why many people use RetroArch only as a backend, launching games through a more intuitive frontend like ES-DE or Daijisho.
🕹️ How to “Consolize” Your Handheld (Set a Frontend as the Launcher)
Want your device to boot straight into your frontend, skipping Android entirely? You can do that!
Steps to set a frontend as the default launcher:
Install your chosen frontend (e.g., ES-DE or Daijisho).
Press the Home button → Go to Settings → Apps → Default Apps.
Choose Home App / Launcher.
Select your frontend.
Now every time you power on your device, you’ll land directly into your beautiful game menu — just like a console.
Tip: Some devices (like Retroid Pocket devices) let you choose launcher behavior at boot — others might need a 3rd-party app like Launcher Manager.
💬 Final Thoughts
Setting up your Android handheld with the right frontend and backend combo is like unlocking its true potential. Whether you’re a tinkerer or just want something that works and looks awesome, there’s an option out there for you.
So ask yourself:
Do you want a console-style experience when you power on?
Are you okay spending 10–20 minutes tweaking a frontend?
Do you like visuals like box art and trailers?
Are you running older games or newer consoles like PS2/Wii?
There’s no wrong setup — only what feels right for you.

Until next time, happy handheld gaming, fam 🎮
