Pretty decent app. I just got it and I’ve been playing it for the past two hours. That definitely says something about the quality. The layout is organized, also I like the customization options, and how many different emulators there are. Of course, there are always downsides when it comes to apps like these. The controls are fine, but occasionally unresponsive, even when I’ve hit it on the right stop. I also want there to be a Sega CD emulator to be added, since I absolutely LOVE Sonic CD and for some reason can’t play it on the App Store anymore. Definitely one of my top 5 best emulators apps.

One-Time-Purchase Option and future possibility of 3DS Emulation.

A terrific emulator, however one critic. It would be nice to have a non-subscription option for those who don’t want a subscription but still wish to support the developers. I want to buy it so that I can better encourage the devs to look into 3DS Emulation as that is currently the most challenging to complete but still possible. Provenance before the update that attempted to merge Azahar and EmuThreeDS into one core was the best current 3DS emulator. But I think there is a chance this emulator could fill that spot and charge money for it as a result.

Beautiful, but Flawed

It is great they are showing love to Sega. Also, the design and Interface is a worthy competitor to something like Delta. However, at the time of writing this review, the app has a fatal flaw. When switching to another app and switching back to AD Boy, the emulator crashes. You have to close the game and re open it to play it, and the autosave might not save you either. I had the same behavior on Sega Genesis and NES testing. I have also seen other reviews concerned about slowdown, but I did not see any in a quick session with Sonic 3 on my iPhone 12 Pro Max. This is a really well made app with great systems, but needs a few bugs ironed out.

Amazing for SEGA games but small issues

Hi! I love that you added support for genesis, game gear, and master system, but there’s 3 issues that keeps it from 5 stars, 1: crashes after trying to import a SEGA CD game, 2: Not being able to play SEGA 32X games, 3: the game you’re playing freezes when you turn off your phone, so please fix this and add controller support!

Really want Controller Support

I’m not sure how difficult it would be to implement but at least on iPhone whenever you have to double tap and hold, the text selection magnifier comes up. That causes none of the buttons to work for a second. Nothing awful, just annoying. Controller support would be awesome, otherwise the app works great! Hopfully Apple doesn’t take this one too lol

Remove controller interface

Looks like controller support is there, as it works with my Backbone, with the exception of the control stick; only the D-pad works for movement. Also, recommend there be an option to remove the controller interface on the screen, especially for when the user is using a controller.

Solid, but a ton of baggage.

The emulation is okay, it runs just fine. I didn’t test anything too gimmicky, so i am unaware of the limitations, but i hate how you need to disable Low Power Mode to actually properly play it. Also, when i opened the app, everything was gone?! My games, my data, all of it was erased..? I’m too lazy to re-add all the games again, so i just never used this app again. Don’t necessarily recommend.

Slow, use other options

This emulator is incredibly slow. Out of all the games I tried, none of them run at full speed. Alternative for Nintendo stuff: I would recommend Delta for retro Nintendo roms of many varieties. Alternative for Master System: If you want to play Master System roms on your phone, I would recommend using Eclipse. It’s not on the App Store, but you can install it for offline play using the “Add to Home Screen” function in Safari. If you want to play. Master system games don’t always play sound on Eclipse, but that’s better than the sound This thing puts out! If you need sound in your Master System games, you can use a tool for PC to convert them to GBA format and run them in the “GBA” section in Delta, though these may drain the battery slightly faster due to the use of a nested emulator.
