## Delta Reviews in United States

### ***** "Great emulator"
Best I’ve played on a Apple device just wish it supported 3ds roms
-- pg502282, 2025-11-10

### *---- "Waste of time"
Was in the middle of a pokemon battle and it just deleted my whole save file out of nowhere. Don’t download waste of time. Scam
-- Phill Mahooters, 2025-11-10

### *---- "Lost half my progress on Pokemon Emerald"
Don’t get this, I lost half of my progress on Pokemon emerald, I’m scared it will happen to my other games.
-- Waldo time and rare, 2025-11-09

### ***** "Help me"
My touch screen and controllers aren’t working for the game, 5 stars over all but I need some help
-- Theorangeditto, 2025-11-08

### ***** "What website is safe"
What website is safe to download roms now days?
-- KiddHaco, 2025-11-08

### ****- "Crashing"
I love this emulator so far but sometimes when pulling up the menu for save states and cheat codes the app freezes and crashes and if you don’t do the in game save first just in case you can lose a lot of progress.
-- Bnbband11, 2025-11-07

### ***** "Best emulator on the App Store"
Everything runs smooth and nice and Ive played pokemon games from firered to soulsilver and they all run extremely well, top emulator easily
-- Reininja0526, 2025-11-05

### ***-- "Huge keyboard issue regarding keyboard cases"
I would rate it 5 stars but the keyboard seems to not work at all on any of the games. It’s also set as the default control method so any time I open the app I have to go into the settings to change the control scheme back to touch screen. I also can not switch apps mid pay sessions because it runs the risk of resetting the control scheme to keyboard, soft locking me in the app, the pause menu I can’t come up because there isn’t one on screen for keyboard mode. From what I can tell when I look online, it seems to only be an issue with the keyboard cases on iPad, but hooking up an actual keyboard to an iPad is super unconventional and most people, including me, don’t have an external keyboard for an apple device. Again it wouldn’t be an issue if the app didn’t want to only ever seem to run on keyboard controls as the touch screen is sufficient for most games
-- Hoi90000, 2025-11-05

### ***** "Phenomenal Emulator"
I've always wanted an easy way to play my favorite retro games and ROM hacks, and Delta has absolutely delivered! It's full of features that make the experience awesome, with save and load states, fast forwarding, and cheat codes.
One feature I think would make Delta truly perfect is rewinding. Maybe the app could take a snapshot of the game RAM every second or two, so players could instantly jump back to fix a mistake or replay a great moment. Even a simple button in the menu would add plenty of convenience and fun.
There is also a bug where using the fast forward feature can mess up the audio of the emulator. Fixing this bug would mean a lot to the people that use your emulator.
Delta is already an incredible emulator. Adding rewind and fixing the fast forwarding bug would make it practically unbeatable!
If you need anymore info, I play Delta on an iPhone 16 version 26.0.1.
-- Thick Bun, 2025-11-05

### ****- "This is the best app, but a little problem"
I really like this app because you can play Nintendo switch emulator games such as Mario kart DS and super Mario 64, but I really like it if it was GameCube emulator or Wii emulator and the Wii u emulator too
-- MarioPro2016, 2025-11-04
