Hello everyone, this is Super Asurada 77.

Meet the RG34XXSP, a retro handheld console in a clamshell (foldable) design with a 3.4-inch screen —
absolutely perfect for portable gaming on the go.

You can toss it casually into your bag without worry and still enjoy your favorite classics anywhere.

The build quality is excellent — and it even lets you have fun with stickers and color customization.
Yes, I tried decorating mine with some stickers too!

---

It weighs only 180 grams, which makes it incredibly lightweight and easy to carry around.

---

The D-pad and ABXY buttons are fairly quiet — not silent, but quiet enough.
In a library, you might hear a faint click,
but in a noisy environment like the subway, it’s barely noticeable.

Note: The RG35XXSP doesn’t have an analog stick,
but the RG34XXSP does. So keep that in mind!

---

If you’ve used any of the Anbernic OS devices before,
the interface here will feel instantly familiar.

---

You can decorate your game list with cover images,
but unfortunately, video previews aren’t supported.

---

You can adjust the screen angle like this —
but honestly, it’s a bit awkward while gaming.

---

The TF1 slot holds the microSD card that contains the operating system.

You can store your games on the same card,
or insert a separate game card into TF2,
but I recommend using TF1 for both OS and games.

If you load from TF2, the system will always ask
“TF1 or TF2?” every time you browse games — it gets annoying fast.

You can adjust the volume using the dedicated side buttons.

---

Here are the shoulder buttons (L1, L2, R1, R2) —
they’re not loud, which is nice.

Charging is simple: just plug a USB Type-C cable
into the USB/OTG port.

---

You’ll find the power and reset buttons here.
If you press and hold the power button while the clamshell is closed,
it’ll turn on automatically.

If you ever find it powered on inside your bag,
it probably got triggered by pressure on that power button.

The TF2/EXT slot is where you can insert another SD card for extra games.

The LED indicators show charge status:

• Bottom LED lights up during charging
  • Red = low battery
  • Orange = mid charge
  • Off = fully charged
• Top LED shows battery level while in use
  • Green = good
  • Red = low battery warning

---

The headphone jack is located on the bottom.
It doesn’t get in the way while gaming.

Performance-wise, it handles PS1 and below flawlessly.

PSP games also work —
especially 2D titles like Super Robot Wars, which run quite smoothly.

Performance is on par with other Anbernic RG35XX series devices.

After about an hour of play, the console gets slightly warm —
nothing to worry about.

---

The stock Anbernic OS includes a music player app.
You can load MP3s and listen even with the clamshell closed.

However, be careful —
if the shoulder buttons get pressed while it’s in your pocket,
it might skip, pause, or restart your track.

Also, there’s no resume function —
once you exit the app, it won’t remember where you left off.

---

You can also play old encoded video files —
the OS includes a built-in video player.
Even with the lid closed, playback continues.

---

Both 3-pole and 4-pole headphones work perfectly —
sound output is clean and strong.

---

When charging, always use a 5V 1.5A or 5V 2A charger
with a KS certification mark (or equivalent safety approval).

⚠️ Important Safety Tips:

• Do NOT use 9V fast chargers or mixed 5V/9V adapters —
  they may damage the board.
• Avoid 5V 1A chargers as well; they can overheat.
• Always turn off the device before charging.
• Never leave it charging unattended while you sleep.

You never know what might happen — safety first!

Final Thoughts

If you’re a beginner looking for a clamshell-style retro handheld mainly for PS1-era or older games,
the RG34XXSP is a great starting point.

It’s compact, durable, and easy to carry —
a perfect travel companion for quick retro gaming sessions.

I personally use it all the time for on-the-go gaming.

Enjoy your retro gaming life!
