Hello everyone, this is Super Asurada 77.
The Anbernic RG40XX H is the latest evolution of the RG35XX H,
upgrading from a 3.5-inch screen to a 4-inch display with a true 4:3 aspect ratio.
It’s designed for retro gamers who love that CRT-era feel with a bit more screen real estate.
As always, the packaging is classic Anbernic — clean and familiar.
Hmm… this time, there’s no protective film included in the box.
The 4-inch 4:3 screen looks fantastic — bright, crisp, and easy on the eyes.
At first, you might think,
“Half an inch bigger? That’s nothing!”
But once you play, the difference is surprisingly noticeable.
When compared side-by-side with the RG35XX H,
they may look similar in photos,
but in real life the visual comfort is night and day.
Your eyes will thank you! 👀
At just 201 grams, it’s lightweight and comfortable even for long play sessions.
For RPG lovers, this handheld is perfect —
the 4:3 screen feels natural,
and your wrists won’t get tired after hours of gameplay.
The small green indicator light at the top isn’t distracting when playing in the dark.
When I first pressed the power button,
I couldn’t even tell if it registered —
it’s that subtle.
Once you get used to it, it’s fine,
but people with larger hands might find it slightly awkward to press.
The analog stick is placed very close to the D-pad,
so occasionally you’ll feel some interference when using the D-pad —
especially during platformers like Super Mario.
It’s a minor annoyance, but noticeable.
The user interface is identical to the RG35XX H.
If you’ve used any of the previous models, you’ll feel right at home.
GBA games automatically adjust to a 3:2 aspect ratio,
and the system adds bezel borders for you,
so there’s no need for manual tweaking.
In terms of performance, I recommend playing PS1 and below.
Some Dreamcast titles are playable,
but you’ll experience lag in demanding games like Dead or Alive 2.
For Super Famicom (SNES) titles like Yoshi’s Island:
if you stretch the image to full screen, you’ll notice frame drops.
However, if you play with a 1:1 aspect ratio and bezel on,
it runs smoothly.
For NDS games:
turn off High Resolution Mode and set Frame Skip to 0
for the best results.
For example, New Super Mario Bros. runs fine —
even with High Res enabled, only the map screen slows slightly,
while in-game performance remains smooth.
PSP games are mixed:
3D titles like Ridge Racer will stutter,
but 2D games such as Super Robot Wars A Portable
run well even at 2× resolution.
For charging, use a 5V 1.5A or 5V 2A charger
with proper safety certification (KS or UL).
⚠️ Important Safety Notes:
- Do NOT use 9V or hybrid 5V/9V fast chargers — it can fry the board.
- Avoid 5V 1A chargers — they can overheat.
- Always turn off the device before charging.
- Don’t fall asleep with the charger plugged in.
You never know what might happen — safety first!
If you want a lightweight, 4-inch 4:3 handheld
that’s perfect for PS1 and older retro games,
the RG40XX H is an excellent choice.
Clear visuals, comfortable ergonomics, and great nostalgia value —
it’s a solid upgrade from the RG35XX H.
Enjoy your retro gaming life!
