Anbernic RG405M Review 2025: Premium Metal Handheld for Retro Gaming

I’ve spent the last 30 days putting the Anbernic RG405M through its paces, testing everything from NES classics to demanding PS2 titles. This metal-bodied handheld represents Anbernic’s push into the premium segment, offering Android 12 flexibility with Hall sensor joysticks at a competitive price point.

The Anbernic RG405M is the best budget-friendly metal handheld capable of playing PS2 and GameCube games with decent performance, thanks to its Unisoc T618 processor and premium aluminum construction.

After testing over 200 games across 20 different emulators, I can tell you exactly what this device excels at, where it struggles, and who should actually buy it. This isn’t just another spec sheet review – this is real-world usage from someone who’s owned 15+ retro handhelds.

For context, I paid $149.99 for my unit from the official Anbernic store, which includes a 128GB SD card preloaded with 3,172 games. That’s about $25 more than plastic alternatives like the RG353M, but the metal build and Hall sensors might justify the premium for some buyers.

RG405M Specifications at a Glance

Build Quality and Design: Premium Metal Construction

The first thing you’ll notice about the RG405M is its weight – at 10.6 ounces, it feels substantial in your hands without being heavy. The aluminum alloy CNC chassis gives it a premium feel that plastic handhelds just can’t match. After three weeks of daily use, I haven’t noticed any flex or creaking, even when applying pressure to the chassis.

The button layout follows Anbernic’s proven horizontal design, with SNES-style face buttons positioned perfectly for my thumbs. The shoulder buttons aren’t stacked (unlike some competing devices), which actually works better for long gaming sessions – no accidental L1/L2 presses during intense moments. The D-pad uses a membrane design that’s responsive but not clicky, which might disappoint fighting game fans.

Hall sensor joysticks are the standout feature here. These magnetic sticks offer smoother, more precise control than traditional potentiometer sticks. I tested them extensively with FPS games and noticed zero drift even after 50+ hours of play. Customer photos validate the build quality claims, showing the precise machining and attention to detail that Anbernic put into this device.

Port placement is thoughtful – USB-C charging on the bottom, headphone jack on top, and SD card slot on the left side. The device measures just 4.45 x 2.99 x 0.63 inches, making it about the size of a Nintendo DS but thinner. I’ve carried it in my pocket for hours without discomfort, though the aluminum can get warm during intensive gaming sessions.

The only design flaw I’ve noticed is the 4:3 screen ratio, which isn’t ideal for PSP games or Android titles designed for widescreen displays. However, this ratio is perfect for classic retro games, which is clearly the device’s focus.

4-Inch IPS Display: Perfect for Retro Gaming

The 4-inch IPS display might seem small by modern smartphone standards, but it’s actually perfect for retro gaming. The 640×480 resolution scales beautifully for classic games, and the 4:3 aspect ratio matches the original format of most retro consoles. No black bars or stretched images – just pixel-perfect retro goodness.

Screen brightness peaks at 350 nits, which is adequate for indoor use but struggles in direct sunlight. I found outdoor gaming sessions challenging on bright days, though indoor lighting poses no problems. Color reproduction is decent with 70% NTSC coverage, but don’t expect OLED-level vibrancy.

Viewing angles are solid thanks to the IPS panel, with minimal color shifting when viewed from the sides. This matters when friends are watching you play. The touchscreen is responsive for Android navigation and light touch games, though you’ll primarily use the physical controls for gaming.

One minor issue is slight backlight bleeding along the bottom edge, noticeable only in completely dark scenes. This doesn’t affect most games but can be distracting during dark loading screens. Overall though, the display strikes a good balance between clarity, battery life, and retro game compatibility.

Android 12 Experience: Freedom and Flexibility

The RG405M runs a clean version of Android 12 with minimal bloatware. This is a huge advantage over Linux-based handhelds – you get full Play Store access and can install any Android app or game. I downloaded Steam Link, Xbox Game Pass, and various streaming apps without issues.

Anbernic includes their custom frontend launcher, which organizes your games by system and provides quick access to settings. It’s functional but basic – power users will want to install Daijisho or another third-party launcher for better organization and customization options.

Button mapping works well for most Android games through the Android keymapper pre-installed on the device. I successfully configured controls for Fortnite, Minecraft, and various touch-only games. Some modern games don’t recognize the controller properly, but that’s more of an Android limitation than a device issue.

The Android experience isn’t perfect – some apps don’t scale well to the 4:3 screen, and performance varies widely depending on optimization. But the flexibility to install emulators, streaming services, and productivity apps makes this much more than just a retro gaming machine.

Gaming Performance: Unisoc T618 in Action

The Unisoc T618 processor is the heart of the RG405M, and it’s surprisingly capable for its price range. This octa-core chipset (2x Cortex-A75 at 2.0GHz + 6x Cortex-A55 at 1.8GHz) with Mali-G52 GPU handles most retro systems beautifully. The 4GB of RAM helps with multitasking and prevents most apps from reloading during switching.

For classic systems (NES, SNES, Genesis, GBA), performance is flawless with 100% speed and no frame drops. N64 emulation runs most titles at full speed with some minor graphical glitches in demanding games. The real question everyone asks is about PS2 performance – and here’s where things get interesting.

PS2 emulation using AetherSX2 is game-dependent. Less demanding titles like Final Fantasy X and Kingdom Hearts run at 40-60 FPS with minimal settings tweaks. However, demanding games like Shadow of the Colossus struggle at 15-20 FPS even with aggressive underclocking. You’ll need to experiment with settings for each PS2 game.

GameCube and Wii emulation using Dolphin shows similar results. Games like Wind Waker and Super Smash Bros. Melee run at 30-45 FPS with occasional slowdowns during effects-heavy scenes. You can achieve better performance by reducing internal resolution to 1x and disabling certain enhancements.

The Hall sensor joysticks really shine in 3D games. The precise control makes aiming in FPS games and navigating 3D environments much more enjoyable than with traditional sticks. Customer images confirm the premium build quality that supports this precision control system.

Thermal management is decent – the aluminum chassis acts as a heatsink, spreading heat across the entire device. During intensive gaming sessions, temperatures reach 40-42°C, which is warm but not uncomfortable. The device never thermal throttles during my testing, maintaining consistent performance over extended play sessions.

Emulation Capabilities: What Can You Actually Play?

Let’s break down exactly what you can expect from each system, based on my testing of 200+ games:

• NES/SNES/Genesis (Perfect): 100% compatibility with full speed, no issues
• N64 (Excellent): 95% compatibility, most games run full speed with minor glitches
• PS1 (Perfect): 100% compatibility, enhanced rendering options available
• DS/3DS (Very Good): 90% compatibility, some 3D games may have slowdowns
• Dreamcast (Good): 85% compatibility, most games run 40-60 FPS with tweaks
• PSP (Good): 80% compatibility, demanding games require settings adjustments
• GameCube (Fair): 70% compatibility, lighter games run well, demanding titles struggle
• PS2 (Fair): 60% compatibility, requires per-game configuration and patience
• Wii (Poor): 30% compatibility, only very light games playable

The 3,172 preloaded games on the included 128GB SD card cover most popular titles, but many are in Japanese or have compatibility issues. I recommend building your own ROM collection for the best experience.

Emulator performance depends heavily on settings. For PS2 games, I found underclocking the CPU to 50-70% and reducing resolution to 1x native significantly improves frame rates. GameCube benefits from disabling EFB copies and using async shader compilation.

The device handles 2D systems flawlessly – even CPS3 and other demanding arcade platforms run without issues. For arcade fans, this is one of the best handheld experiences available, with perfect MAME performance and the right screen ratio for classic games.

Battery Life and Thermal Performance

The 4500mAh battery provides solid endurance, though actual runtime depends heavily on what you’re playing. Here are my real-world measurements over 30 days of testing:

• 2D systems (NES, SNES, Genesis): 8-10 hours
• N64/PS1 games: 6-7 hours
• Dreamcast/PSP: 4-5 hours
• GameCube/PS2: 3-4 hours
• Android games/streaming: 5-6 hours
• Standby: 48+ hours

Charging takes about 2.5 hours via USB-C, and you can use the device while charging. The battery holds its charge well when not in use – I found it only lost 5-10% charge over a week of standby.

Thermal performance is better than expected. The aluminum chassis distributes heat evenly, preventing hot spots. During intensive PS2 gaming, the device reaches 42°C but remains comfortable to hold. There’s no fan, so operation is completely silent.

One concern I noticed is battery drain during sleep mode – the device sometimes uses more power than expected when idle. A quick reboot usually fixes this issue, but it’s worth monitoring if you’re concerned about battery life.

Final Verdict: Who Should Buy the RG405M?

After 30 days of intensive testing, I can confidently recommend the Anbernic RG405M to specific types of users. This isn’t a one-size-fits-all device, but for the right audience, it offers tremendous value.

The RG405M is perfect for retro gaming enthusiasts who prioritize build quality and want a premium-feeling device. The aluminum construction and Hall sensor joysticks make every interaction feel satisfying, and the Android flexibility opens up possibilities beyond just retro gaming. If you’re tired of plastic handhelds that feel cheap, the RG405M’s metal chassis is a game-changer.

It’s also ideal for users who want an all-in-one device that can handle retro gaming, streaming, and light Android gaming. The ability to install Netflix, Steam Link, and various emulators makes this a versatile entertainment device that goes beyond just retro gaming.

However, you should skip the RG405M if you’re primarily interested in PS2 gaming or want the absolute best performance for demanding emulators. The device struggles with some PS2 titles and can’t match more expensive options like the Odin Lite for modern Android gaming.

At $149.99, the RG405M hits a sweet spot between build quality, performance, and price. While there are cheaper options and more powerful devices, few combine premium construction with decent emulation capabilities at this price point. For retro gaming enthusiasts who value quality over raw performance, the RG405M is an excellent choice that should provide years of enjoyment.
