Exceptional, best vintage emulator on the App Store!

It’s really cool to think how far we have came in terms of gaming in the last 20 years. 7 systems seamlessly on 1 device is just… amazing. This application brings so much joy to me, playing my childhood DS games. I ended up losing all of my childhood games on a flight when i was about 12 years old, and since then had been wanting to play the games again. I ended up loading all the games that I had lost into my library on the application 🥹 There are no bugs and the AirPlay integration is so cool, it just has a bit of an input delay.

One thing I wish was changed: when AirPlay is being used with a controller on DS games, the “lower-half” of the DS screen is not displayed, which is quite annoying. I think the expected behavior should be to have the “top-half” screen shared to the AirPlay device, while the “bottom-half” touch sensitive screen is present on the phone, so it is still able to be used.

Regardless, this app is the best thing to hit the app store and to hit the gaming industry in a really long time, and I’m excited to see how much further the developers can go with it in terms of devices and functionality. I will happily make a Patreon donation to promote the development of this application. :)

Great emulator that just does its job right!

As a new iOS user, I'm glad that you can now use emulators officially without having to sideload, and I think that's awesome! There's not a whole ton of variety though, since at the moment, only Nintendo consoles all the way up to DS (excluding GameCube) are available to use. I was really hoping to be able to emulate Sega Genesis/Megadrive games right off the bat, but as I looked into it, it's still in beta development! I'd love to opt into the beta features, but I'm assuming that's a Patreon exclusive. I hope you guys can add more customization options too! Personally, controller skins are neat, but I'd love it if there was the ability to use filters and such, like an old CRT filter that blends in the pixels and smoothens things out a bit so that the dithering in certain games looks the way it was meant to be, like the Sonic 1 waterfall! Playing games in pixel-perfect integer scaling (so there isn't any weird pixel simmering on the screen) would be great for people who just like even pixels. As far as I know, there isn't a way to change the aspect ratio either. Some games look nicer when they're displayed in 4:3 instead of 8:7, which is the native resolution for both NES and SNES.

Exceptional Emulator with a Slick Interface – Delta!

//1. I've been using the Delta emulator on my device, and I must say, it's an absolute joy. The interface is clean and uncluttered, which makes navigating through settings and games an effortless experience. //2. There are no annoying ads to disrupt the gaming session, and the smooth operation enhances every aspect of gameplay. The convenience of the emulator is top-notch, thanks to its intuitive controls and compatibility with a wide range of game formats. It brings back all those nostalgic moments flawlessly, running classics without a hitch. //3. However, there's one feature that would make Delta even better — expanded cloud sync options. Currently, it supports Google Drive and Dropbox, which works well but integrating iCloud sync would be a game-changer for iOS users. This addition would streamline game data management across all Apple devices, making it much more accessible and secure. //4. In conclusion, Delta is a superb emulator that offers a premium nostalgic gaming experience. If iCloud support were added, it would undoubtedly be the perfect package. Highly recommended for anyone looking to relive their favorite gaming memories on the go!
