Audio Problems / LagI had some problems with this emulator when attempting to play Luigi’s Mansion Dark Moon. Just loading the title screen had so much lag, but I was kind of expecting and willing to compromise on it. What I couldn’t was the audio. It was just a buzzing sound. No matter how much I changed the audio settings and closed the program and app to make sure that it was applied, nothing changed, so I gave up, considering that this costs money unlike the other emulators, I expect a bit more, however as of now, this is the only emulator I could find that can do 3DS on IOS. The game did in fact load. I didn’t want to bother past the title screen albeit. But it is possible. I hope the money that this app gets will be reinvested back to itself to improve itself..Version: 1.13

❤️👍Take All the Time U NeedLook i paid for the app yes and i appreciate being able to play 3ds games on my phone at all i am also very patient and to be honest for years AppStore never had any emulators only way to get them was slightly difficult it is easier to get them now and appreciate it and i love it and this emulator possesses a-lot of potential but work takes time from the dev and takes patience from the user so i understand i don’t care about the problems every emu started out having a decent amount of problems at the beginning as long as even 3 or 1 game i play on the 3ds emu is working and functional i am happy i have hope that this app will be a great 3ds emu don’t let the others get u down they are just impatient and expect everything to get done quickly without any side effects or problems u just u do u.Version: 1.10

Good, but some problemsSo look, Folium is a wonderful emulator, with the ability to play 3DS games being really cool, but while it's a technical marvel, there are a few bugs. The first one is simple, Folium's D-pad, whilst you should be able to change from pressing right to pressing left like a regular d-pad, Folium's won't let you make that quick change in direction, this is a big problem for 2D platformers like Super Mario Bros, in which you should be able to switch directions in a flash. The next problem is how Folium doesn't import 3DS & NES games on the fly, while you should be able to import those games like the DS, instead, you need to drop the roms into the emulator's ROM folder. And finally, on my iPad, when using landscape, it stretches out the DS & 3DS screens, I don't know why it does this, but it's kind of weird that it happens. So yeah, those are all my complaints..Version: 1.10

Dude, get some help.I understand needing a mental health break, take all the time you need. That being said, I paid for this app and have been disappointed update after update. Each update seems to fix one problem but cause three more. Can’t play with Backbone as on screen buttons still persist. It just kind of irritated me seeing you celebrate this last update as a success when the app is nowhere near state where I would even consider trying to use it, and now I’m just left waiting again. Get some other developers or something. Either that or pull the app until it’s actually ready. Please..Version: 1.10

Great For Pokemon (15 Plus)With a little tweaking, and some internet digging, this app is everything I need it to be. Sure my phone heats up a bit and the game crashes every so often, but I’m sure those things will resolve with time and updates. But if you’re considering this app to play Pokemon, it certainly gets the job done. Just be sure to do your research! There’s Reddit and Discord-goers that would happily help refine your experience. Kudos to the developer for constantly putting in the effort. Making something like this for iPhone ain’t easy folks!.Version: 1.10

One more update to “perfection”This recent update (sometime within the last few days) + previous update boosted performance a lot!! For context, I have 13 pro max, usually play pokemon omega ruby & ultra moon & occasionally Spider-Man edge of time (purely to test max performance). Only problem is now when I try to use backbone controller the screen goes black. Before, it would show on screen controller with this plugged in, and before that controller-functioning was perfect but the games lagged. So basically the update was 2 steps forward, 1 step back. I’m thinking one more update to fix controller compatibility will make this emulator close to perfect..Version: 1.9

FoliumIv been playing omega ruby and been looking up ways to add cheats to the emulator. Not sure why cheat engine would be removed but the cheat folder is still available to add files to! I do still play the games and enjoy the emulator. I just wish that things wouldn’t be added and then taken away. Still a great platform and I’ll continue to use. Just wish the cheat option would return to make it more user friendly instead of spending 20 hours off and on trying to figure out what I’m doing wrong and why the app is not working only to find out the option was taken away!!!.Version: 1.10

Ok, for nowEach game i have seems to crash after playing for 15 minutes (only one out of seven does not), so maybe the next update will fix this? I also should mention some of them completely freeze in very specific spots of gameplay. Also, what kind of emulator does not have save states? I guess it can be to prevent cheating, but with all these crashes, it would sure be helpful. Also also, i know it will not happen, but i would like a gamecube and wii emulator from here? Of course, JIT is required for these systems, but it would be nice to have a option..Version: 1.10

Interface is not workingI just bought it and literally the interface is mot working at all. I was super excited when I heard this app supports 3DS games, but I don’t even know if I can use the app if it won’t load anything at all. 😭😭😭 Edit: I’m now aware that there’s a reason why, and that a new update is coming soon, so hopefully that gets released and fixes any bugs on iPad! 🙏.Version: 1.12

Great but has some problemsThis app had been a great experience and I’m glad it runs some of my favorite games well. But hears the bad news when I try to plug in my backbone controller into my iPhone the screen would automatically go to black which is unplayable when not visible, secondly the layout options for how the screens look has now suddenly disappeared which was really nice to have. I really hope this gets fixed soon, I was really looking forward to playing games with my controller..Version: 1.9

Can’t import aes_key files anywhere on here.I love the idea of the emulator and now that I have a beans new iPhone 16 I really want to try and get it up and running. Problem is, I know when I had it on my old phone, it asked me to import aes_key files in order for 3dd games to run. Since getting it again on iPhone 16 I see no alert for the files, nor anywhere to import them to the app. This means I can successfully add 3ds games to my library, but I can’t even get them to play..Version: 1.10

I believe in you!!While I haven’t put substantial time into this application, it so far can run the few games I sought to play on my Iphone (Etrian Odyssey Nexus, puyo tetris). This is the only genuine 3DS emulator on the IOS appstore without having to go through the round about process of side-loading. For the sake of accessibility and shear potential this application has, I would recommend it to anyone whose willing to be a little patient with setup and updates. You got this dev!!.Version: 1.12

Worth the money now!Before the update that came out a few days ago I would have said that this was not worth $5, but now that this new update has come out I would definitely say this is worth buying. The only bad thing I have to say is the layout but I know the developer has said they will be fixing it any day now..Version: 1.7

UpdateAfter this app received an update the Cytrus core now works properly! I have been enjoying Pokémon Omega Ruby and One Piece Great Pirate Colosseum. Adjust the core settings to fit your specific device. The core still isn’t fully optimized, so my phone can’t play Pokémon or other large games. However, my iPad which is newer can support almost any game..Version: 1.10

Accomplishes what it needs to.It’s not going to work on older devices, but I understand that it probably takes quite a bit of power to run the emulator. It has bugs, and sometimes, there’s game-breaking updates, but it works. If you expect it to work flawlessly, maybe just get an emulator on your PC. This is the best way to emulate 3DS games on iOS as of right now though..Version: 1.13

Really improved!There are a lot of negative reviews from the early days of this emulator, but it has come a long way. I can play most of my games at normal speed and with the addition of multiplayer, I’ve played a certain fighting game with randoms, and traded pokemon as well. It is way cool and I definitely believe it is worth the $5.Version: 1.12

Improved performance!!So I’ve happily played about 25 hours of Animal Crossing New Leaf already, but this new update (9/8) really fixed every problem I was having! The game runs a lot smoother and no more slo mo or glitchy audio. 😎 The settings panel is more streamlined, and the buttons have haptic feedback now. Thanks Jarrod! ✌🏻.Version: 1.7

Good investmentGot the app awhile back the games were unplayable if you could make it past the loading title screen the recent update makes them “functional” super excited to see what future updates will bring.Version: 1.10

Unrealistic expectationsMany of these reviews are from people who don’t understand the state of emulation on IOS, and the constant battle this developer is at to just have this app up and running through Apple. There is ABSOLUTELY room for improvement just like any other emulator. The problem is not folium, it’s apples reluctance..Version: 1.11

SlowUpdate 1.12 made it so that every time I try to start the app it crashes on iPad M2 iOS 18.1 beta but 1.13 fixed it and I understand that performance is low but by changing some settings and being patient, it is playable.Version: 1.13

Keep goingWhile with every new update may come a new error or something wrong, with the consistency of the updates I can definitely tell your trying your best to make it as good as possible, keep trying eventually folium will be amazing.Version: 1.13

Awesome, but wanna tell some people stuff.So, I’ve been seeing people rate this app like it’s really bad. It’s not the folium devs fault. Stupid apple won’t allow JIT for iOS, for those who don’t know without JIT emulators don’t run very well. Please stop writing bad reviews it’s not the folium devs fault..Version: 1.11

Well worth the money now.Newest update made a lot more games playable, I’d still recommend a controller because the built in buttons aren’t good (I’d recommend a controller for all emulators anyways) I still love delta and will use delta for Ds and snes emulation but for 3ds folium is really good. I love playing shovel knight on my phone!.Version: 1.7

The app is the best 3rd gameHowever they do need to fix some error with the gameplay but if you just close the app and open back up it will work but some of the game won’t or some of them will glitch so yeah pls update pls make it better.Version: 1.11

Bring back the cheatsI’m willing to pay for you to bring them back like a premium feature or something.Version: 1.10

WORKS FINE WITH CORRECT SETTINGS I WAS ABLE TO PLAY POKEMON SMOOTHLYI was upset at first because Pokemon was running bad but I google some settings to tune the emulator and it’s running like an actual 3ds and now I can enjoy Pokemon thoroughly best 5 dollars I’ve spent in awhile.Version: 1.10

Works goodIm on iPhone 14 Pro Max and it works pretty good. It’s a little laggy every now and then but it works fine. The only thing I don’t like is that my phone gets hot and drains battery very quickly. I lost 20 percent in 40 minutes..Version: 1.10

The apps okayIt’s a little laggy on older iPhone it’s perfect when you optimize it to your phones need but it gets a little laggy.Version: 1.10

Hoping the dev fixes up the bugsHas a lot of promise. But the last update won’t let me enter in any of the games… plus I now have triplicates of each game. I’ve heard good things about the recent update but as of then…. My iPad will have to wait..Version: 1.9

I love the emulater BUTThe issue is any type of controller I try to connect even a backbone the screen goes back the game runs smoothly and everything but I’d prefer to play with a controller and it’s not allowing me to do that could you please fix.Version: 1.9

Not perfect but shows potentialIsn’t running the best but I can totally imagine it getting better over time, also hoping for when smt 4 will run 🙏.Version: 1.11

Needs work but pretty good for what it does.It won’t play certain games without just-in-time support. It can play some though, like Pokémon oras or fire emblem awakening. Needs cheat options though..Version: 1.10

It’ll eventually become perfectTake your time bro no need to speed up the process just creates more bugs.Version: 1.10

Good, but need more changeThis is the best emulator without JIT on ios, hopefully there is a way to get jit.Version: 1.14

Only option on iOS for 3DS games. Need save state feature ASAP!!!Cons: - No Save/Load State option - Low Performance on default settings (Audio & Video lags/ stutters every now and then) when using iPhone 12 Pro Pros: - Can play Nintendo 3DS games Summary: Not as good as Delta emulator but only option on iOS for 3DS games..Version: 1.13

This is trashI can’t even add aes keys since the new update and the game keep crashing please fix it and make it playable like delta Emulator and the cheats doesn’t work like that either ..Version: 1.14

This is actually really good!Although people say that it is awful for 3DS emulation without JIT but i think otherwise. If you have the right device and you experiment enough with settings you can achieve great performance. I truly think this emulator is absolutely wonderful for 3DS emulation without JIT and i cannot wait to see where it goes on the future!.Version: 1.13

Lags a lot even when cpu is 5Only choice for 3Ds games which I’m very grateful for, but would be wonderful if you can improve the system, especially the sound and improve the laggy gameplay. Used on iPhone 15.Version: 1.13

UI needs updatingOther than the horrible UI everything is good. The UI doesn’t even have the proper controls for the 3DS. It looks like a teenager just learning coding tried to make the UI.Version: 1.1

It won’t work?!?I’m trying to launch 3DS games and all I see is a black screen (UPDATE) some apps don’t work sadly like Mario 3d land but gonna give a better rating tho.Version: 1.10

Nothing else like this but the recent update has issuesIt’s the only app to emulate 3ds at the moment but the recent update makes it not work on my iPad. My iPhone 12 works and has gotten a performance uplift from the this update though.Version: 1.9

Good, but needs a few thingsThis runs pretty smoothly when you apply the right settings (Reddit helps) on a 15pro. After 1.6 update, the app crashes every time you apply a setting change. One more star if we get save states and button transparency control..Version: 1.6

Great to see 3DS on iOSIt runs pretty great on the 15 Pro Max. Pokémon games run at near full-speed (very playable), and I’ve had a good time playing Ocarina of Time for 3DS too. If you’re on an older device, your mileage will vary, but Apple is pretty lenient with their refund policy, so keep that in mind if you’re concerned about wasting any money on the app. As far as UI goes, it’s pretty basic and missing some basic features like returning to the Home Screen or layout screen options, but I’ve got it on good authority to say that these are being worked on and will hopefully be added in the coming weeks!.Version: 1.1

Keyboard glitch and freezingI’ve been trying to play tomodachi life on folium and have been so excited for folium to be released but I can’t get passed the making mii stage without my game freezing on the keyboard. The keyboard also overlaps and puts what was typed from the past into a box I’m trying to write in. I really want this to be fixed..Version: 1.2

So far so good!Seems to run pretty well on my 12 pro max so far, but with the only frame drops coming from texture loading from what I can tell. UI needs work for sure, but it’s serviceable. Played with a backbone and the controls were on the screen still so I don’t know if that was just a glitch, but if not I would definitely like to see the ability to remove the controls from the screen in the future when an external controller is plugged in..Version: 1.3

Near perfect!Runs well on iPhone 13! Little glitchy but it’s to be expected. Only thing missing is an easy way to use cheats! Other than that, it’s perfect!.Version: 1.3

Smooth Gameplay i14ProMaxOn the 1TB i14ProMax and its working well!.Version: 1.3

Great start for an IOS 3DS emulatorSeems to play well on iPhone 15 pro max. really hope a fix comes so when you switch to a different app you don’t have to load the entire game again. Make sure you save, or you’ll be sorry haha. i hope this emulator is only a beta stage, and will be worked on. Need more customization like moving controls and a touch joycon, skins, a button to slow move for Pokemon ultra sapphire..Version: 1.1

3DS support sucks on MacWindow can't be resized, you need to go to settings to enable keyboard and mouse, and there are no in-app settings, only MacOS settings for the app. As the app is not properly configured for MacOS, its file management is kind of odd and it is not particularly fast. Crashes are rare, but stretched or cropped, sometimes completely invisible windows or game screens, are not. You will need to relaunch the app many times before it works. but it's probably good for non-3DS games, looks like it doesn't focus on 3DS.Version: 1.1

Its okayIts a real emulator, lots of 3DS games crash on launch however Controller UI is pretty bad.Version: 1.1

WowI refuse to believe the same person who made delta made this.Version: 1.1

Black screenThe emulator is amazing but some 3ds games, I can’t play as it just a black screen.Version: 1.1

GreatAwesome to have 3DS emulation officially on the App Store. However the developer should mention in the app description that 3DS emulation will only run smoothly on newer higher end devices, especially since the app is paid and someone could waste their money buying it when all they have is an older iPhone..Version: 1.1

Could be betterPlaying on iPhone 15 pro almost nothing plays at full speed tones of room for quality of life improvements.Version: 1.1

Great start - some rough edges to work on🏆 I applaud the developer for the work to bring it to the App Store! 🥇 It runs games wonderfully on my M4 iPad Pro 🥈 It runs less well on my iPhone 15 Pro 🥉 Runs .cia (not .3ds) files great 🚧👇- areas needing attention - 👇🚧 ⚠️ Sound glitches common ⚠️ No in-app help/docs ⚠️ No iPad OS UI (iPhone UI only so far) ⚠️ Only video filters, no other customizations.Version: 1.1

Smooth and fast (iPhone 15pm)Best emulator so far especially since it has 3ds support!.Version: 1.1
