I have just started playing and the app was so easy to use, all you had to do was download your own rom and insert the file and youre all set, the app does literallly all the rest for youUPDATE: alright after a while using this app its really solid and amazing app, only complaint is that it sometimes slows down the gameplay whenever anything external happens(eg. text message recieved or call recieved) but otherwise its a great appUPDATE 2: This is probably gonna be the last time i update but the app has way better features now and its smoother than it was before the update but i still freeze a lot when i open an external app/browser, good thing is theres autosave so there no real complaints aside from that
3DS works pretty well! Few issues though
MageEspeon
I got this to revisit the 3DS Pokemon Mystery dungeon games as the battery in my old 3DS went pillow-shaped a few years ago and the whole thing had to be disposed of. I tried out a couple emulators and this one has significantly less audio popping and crackling, though it does occasionally stutter, especially in parts of the games with a bit more going on. My phone being at lower battery also seems to mess with this, even if low power mode isn’t turned on. I’ve encountered a few crashes, which definitely could be annoying, especially with the fact that the only way to have more than two save states is to buy the premium version, and the quicksave button will always try to make a new state instead of replacing the last quicksave. Still, this emulator works decently well and is easy to set up. It also supports tilt controls in games that have them! It can’t do anything for features that required the 3DS camera as far as I could tell though. A couple other things to note are that this emulator will run down your phone battery pretty fast, and personally I’ve felt my phone get physically quite warm in my hands while playing. Also, while the simple settings menus and such are easy to understand, there aren’t as many options as other emulators might offer. I haven’t seen any sort of “advanced settings” dropdown or anything
Good For Casual Gaming
MothTheFirst
I got this since I was bored and wanted nostalgia anyways it’s good none the less if you want 2x speed it’s kind of laggy but it’s good at regular stuff (gb 3ds are the ones I tryed) but they don’t tell you specifically that you need to save and how to go to normal speed (you have to hold the speed button till a thing pops up) but if you know that it’s good there aren’t any ads or stuff and it’s good for casual play idk if it works offline or not but still fun so if you want casual games it’s fun (btw you have to download the game if you did not know its ez to just try not to get hack and try to find the smallest file [less than 2g is good but more it might not work] since bigger files tends to not work hopes this helps bye)
Overall good

The games run decently, the best emulated console in this emulator is (in my opinion) tied between Game Boy advance and PlayStation Portable, I’ve played these 4, 3ds: laggy and not very good. Dreamcast: descent just not very powerful when playing sonic games, especially adventure 2, the frame rates drop to about 18fps and i feel like the main fps is 30, and the audio is horrible. This applies to all Dreamcast games. I exceptionally love how there is no ads, if there were, that would drastically decrease my interest. And change the rating. And the other consoles: PSP: works well (audio is GREAT) except PPSSPP is much better. Game boy advance: Works EXCELLENTLY with great audio and gameplay performance. If you consider adding GameCube to the list, (it would have to work well) I would give this 5 stars, or if you improved audio performance and fps functionality.
