I have using this emulator for a long time now and it’s very good but I have a suggestion like it should have a option to adjust game screens size and it should have skins for iPad landscape mode and it also have some bugs but after all it’s a good emulator And I think you should make free 3DS emulator for IOS iPhone and iPad, I think it might be great to have.
Long time no see

I have been a long time delta user sideloading it with help of Altstore, happy to see it make its way to AppStore.The user interface and ease of use is the best part about this app, it may not be the most feature rich but the Control skins makes up for it.Audio latency could be improved other than that no issues!
Childhood returned

The moment this came out I downloaded it… been playing Pokémon red ever since I really wish there was a donate button or a app charge as the dev deserves to be compensated for this beauty of an app. I will give to their patrion as I know that’s their revenue model Only complaint is the battery drain about 10% per hour of play on my iPhone 15 pro max
Childhood dreams... do come true.

I'm playing a monster-catching game, pika pika, on an iPhone! .This emulator is so easy and top-notch. Thank you devs and designer for this. Adding ROMS is as easy as searching for a game>downloading it>opening it in the app>and revisiting your kid self.This is like Winamp for classic gaming. Beautiful skins to book, has haptics, this is what the developer community can do. Amazing goodness.
