Miyoo Mini V4 OnionOS Handheld Game Console 2.8-inch 750*560 IPS Screen Miyoo-mini v4 Onion-System with Portable Case T-Black

I have about a half dozen of these handheld emulators. I tried to pick up the Miyoo Mini about a year ago, but due to shortages I was never able to get one. I moved on and got an Anbernic RG35XX. I found myself hardly ever using the RG35XX and I'm not really sure why. It still has the stock OS so I think that has something to do with it. On Black Friday, I saw a sale on the Miyoo Mini and somehow justified a purchase even though I've got several vertical handhelds. I heard good things about OnionOS so I decided to spend a little extra and get the one that had it right out of the box. That was a mistake. Don't get me wrong OnionOS is great, but I've since got a new micro SD card and you can't just copy the OS from one card to the other, so I had to install it from scratch, and it was so easy it is not worth it to pay more for a card with OnionOS installed. I recommend when you get your Miyoo Mino to take the card out and back it up somewhere so you have all the roms it comes with. Then throw that card in a drawer because it's not a very high quality card and will likely fail. Get yourself a good 128GB Sandisk, Lexar, or Samsung micro SD Card and use that as your starting point. Next, Google "miyoo mini retro game corps". The guy that runs the site Retro Game Corps, Russ, has lots of great informative videos and instructions on how to install OnionOS and it couldn't be easier. Once you have OnionOS installed, then transfer your roms and bios directories over from your backup to your new card and you should be good to go. I now find myself playing this handheld more than any other, and not just because it's new to me. The OnionOS experience is great, and I think that has a lot to do with it. The size, while small, is perfect for certain games. The Miyoo Mini is fully capable of playing PSX games, but depending on the game it's a little rough. I don't recommend this if you primarily play fast pace action games that use the shoulder buttons. I find myself mostly playing older RPG games that I missed out on. It's easy to even play one handed. So far, I haven't had any issue reading any text in games. The screen is crisp and the colors are vibrant. My only knock against it is the green LED on the translucent model bleeds through the plastic and it's very distracting. It's too bad it couldn't be turned off via a setting, but I guess that's impossible. It would take opening the case and painting over the LED, which is certainly doable, but I had to replace a screen on the RG35XX before and I broke off a few clips in the process, so I am a little hesitant to do anything like that now. What makes the Miyoo Mini so great? It's small but still comfortable. The controls are great (except for the shoulder buttons). Onion OS is an absolute game changer and sets the bar on how good an experience with these types of devices should be. It is just so easy to slip into a pocket there is no reason not to take this with you just about everywhere. I would love to see a v5 with wi-fi and Bluetooth, along with brilliant OnionOS support for these features.

Oh my goodness, this thing has changed my life! Retro gaming at any time anywhere! It's so portable! I've tried other retro consoles in the past but this one quickly became my favorite due to it's comfort, size, customization and "GameSwitcher" ability. It turns out I like switching out my games constantly and frequently! It's been absolutely perfect for Pokemon and Final Fantasy games, buttons can be mapped to be used one handed. There's an activity tracker as well if you are into that. System feels smooth and comfortable in one hand although, screen is not the best quality, I personally do not like using overlays on the Mini because I feel it makes the game look much too dark. The first thing I did though was obtain a brand new 128GB micro SD and install a fresh version of OnionOS since I've heard horror stories of SD cards packed with these retro consoles. After OS install, I was able to add over 3,000 retro games from Arcade to PlayStation to Wonder Swan Color! I loved it so much, I ended up buying a Mini Plus because you can switch the SD cards back and forth, the key difference being the Plus has wifi and the Mini does not. Customization has been a delight on this thing, there are many enthusiets that sell custom buttons, stickers and shells for these to truly make it your own. I've been using the Mini for on the go travel and the Plus for home. You can't go wrong with either!

Such a cool little console. It's not a hardcore device, but its great for travel. Airports etc. Great battery life.

UPDATE: I’ve been keeping this in my EDC bag. It fits where my MM+ does not, meaning I’ve actually ended up using this a little more than my Plus to my surprise. It is in fact good for RPGs, but I’ve also played Mario and Donkey Kong on it without issue. Overall, I’m pleased. Just keep the poor QA in mind before purchasing. EDIT: I have ultimately decided to keep the white Mini v4 after spending some more time using it. For whatever reason I can’t bring myself to part with it even though it’s pretty impractical (and only about $5 less than the MM+). I definitely wouldn’t want it as a standalone device. You need something a little larger to comfortably play at home, but the v4’s compact size is too appealing and pocketable to ignore. I can see myself potentially taking it with me out and about, but we shall see. It’s supposedly perfect for RPGs. Even if I don’t use it regularly, it’s still a decent-enough back-up if something goes wrong with my Plus. I may even end up selling the v4 in a few years after the remaining stock is gone, and they’re difficult to find. Side note: it’s very easy to spend 3x the price of the actual handheld on modifications. The mod products are rather pricey in relation to the cheap price of the device. I spent $35 on the upgraded buttons for my MM+ alone. Just keep that in mind. A microfiber sunglasses sleeve works well as a thin layer of protection for the Mini, and even the MM+, depending on the size of the sleeve. It’s not a perfect fit length-wise, but the Goodr one I have is spot-on for the width. If you have one lying around, give it a try. You can’t beat free. FURTHER EDIT: After a few returns, I have received a quality device. Whew, a lot of trouble, but I really wanted one of the minis. Ended up with a white unit. It’ll do. Turns out the white and yellow have the same type of finish on them, matte, not as sleek or shiny as the transparent models. I initially thought the yellow one I received from a different seller seemed off due to the texture and overall feel of the unit, but that’s just how they are. I am so relieved I managed to get a good-quality v4 before they’re all sold out so I could really see what it’s like to play, but truthfully, I’m not all that impressed. Let’s be real; it’s more of a novelty item at this point. If you didn’t buy one when they were first released, you’re probably not going to appreciate it as much because there are “better” alternatives available now for about the same price (MM+ for example). The Mini is really almost too small for comfortable two-handed play. The Plus is much more ergonomic with a larger screen while still being portable. It feels better in my hands, and overall it’s just more enjoyable to play. It’s honestly the perfect beginner device. I’ve even modded the buttons which has given the cheap device a more premium feel. I’d recommend the Plus over the Mini for most situations. I have attached a photo of the v4 next to my MM+ for reference. Spend your money more wisely unless you are a long-time lover of the Mini or have extra cash sitting around begging to be spent; it probably won’t cut it as a standalone handheld for the majority of people just entering the retro gaming scene in 2025. I now kind of understand why Miyoo made the decision to discontinue the Mini. Those who wanted one, bought one when they were released, and they are probably the only people still consistently buying them to replace their old ones out of some kind of sentiment or because they’re just used to it. Well, them and people like me who wanna get in on the action, and then end up disappointed because it doesn’t live up to the hype. The customer-base for this particular model is probably drying up at this point. It’s a buy-it-just-to-have-it thing for me, something that may not get a whole lot of use, but the sheer cuteness of it makes it hard to give up. I say that as a newcomer to retro gaming. The sentimentality of the mini is lost on me because I simply just wasn’t there. As someone who isn’t blinded by the novelty of the mini, the MM+ is truly a much better device in almost every way. The only true difference is the larger size which doesn’t allow you to slide it as effortlessly into a pocket. Some women’s pockets are a concern as usual. That’s not something I’d probably do or recommend anyway, however, considering these devices are notorious for being fragile. The larger-yet-still-small size is actually a benefit. If you buy one of these as your only handheld in 2025, you’re kinda crazy. Buy the MM+ if you’re only in the market for one device. EDIT: Changing my initial rating of 5/5 to 4/5 due to the inconvenience of ordering and returning so many devices in an attempt to get one of good quality. I seem to be experiencing a QA problem with the devices I’m receiving, or maybe Miyoo devices are truly just poor quality in general. After flipping through menus and setup for a few minutes on one of the mini v4 units, I noticed the dpad is a bit janky; it doesn’t always respond. It wiggles a bit too much in its shell cutout, little too loose. It also looks like all of the screws are stripped, like someone considered modding it before deciding to return it. That could actually be what’s wrong with the dpad. Unfortunately, I will be returning the black one. I ordered a purple Miyoo Mini Plus from FINGEREVO before ordering two of the Minis. After learning that Miyoo was discontinuing production of their Mini v4 devices, I decided I should probably order a couple of them to see what all of the fuss was about. They come highly recommended by the retro gaming community, of which I just recently became a member. I had some FOMO and ultimately succumbed to the pressure of the shrinking inventory. The yellow, blue, and retro gray are becoming increasingly difficult to find, and if you do manage to find them, they cost more. I decided to buy the black and white from FINGEREVO. I still don’t quite understand the hype, but they are very cute and pocketable. You can literally take this device anywhere you wish. The MM+ is great too (better in most cases), but the Mini does scratch a certain itch for some. There’s something about the size and functionality of it that will really hit the sweet spot for a particular type of person. I feel like a giant playing games on this thing. It’s both good and bad. If you’re unsure, just order it because once the stock is gone, it’s supposedly gone for good. You can always return it easily through Amazon if you decide you don’t wanna keep it. I returned and reordered multiple devices trying to get my hands on a good-quality unit. Fourth one was the charm.

Love the mini v4, perfect for everyday carry even tho I have a RP3+ and rp5 I still seem to keep coming back to my mini 4v

La mejor consola, chiquita, bonita, los botones se sienten bien y le puedes poner OnionOS.

My kids young/ old they love it!

When I powered the device on for the first time it showed white scan lines and it wouldn't boot up. I was worried that I got a defective product but then I found out that the 64gb sd card it came with was corrupted. I wasn't expecting to use the original sd card though and ordered a 128gb one prior. It works fine after removing and replacing the original sd card. I got the normal non-onion os version because it was cheaper; installing onionos on it took like 10 minutes. It's perfect and I'm more than satisfied.

I thought the small form factor was what I wanted. It's just too small to be enjoyable for me to play. It's cute, but I know I will rarely use this. If it was meant to be my one and only handheld, l'd probably keep it. But it's not. And not worth the eye strain. I am tempted to keep it as a 'collectable' but I'll most likely return it. The miyoo mini plus is more or the 'mini' form factor I was looking for. Thankful Amazon accepts returns.
