Having Trouble with Mic in Delta

For me, it’s always just worked, maybe make sure the app has mic permissions given?

If you have an iPhone with a Dynamic Island, look for a little orange dot when playing DS games. For me, if I have a DS game open that is using the mic like Phantom Hourglass, I always see a little orange dot in the middle-right area of the Dynamic Island letting me know the app is using the mic.

Another thing, you have to be quite a bit louder than the actual DS mic since the iPhone has noise canceling so some things like blowing out the candles in Phantom Hourglass you gotta blow hard directly into the mic.

Pro Tip: If you just move the folders correctly into the Delta app, the audio works now!

Also, try restarting your iPhone, sometimes, this simple fix also solves your issue.

  1. I can’t verify the app it says “Failed to verify code signature” “The executable was signed with invalid entitlements.” does anyone know how to fix this?

  2. Hey, I have a different experience of crashing – I can add & play roms/games through the delta emulator.
    However, it keep crashes in 5-10 minutes when playing the game.
    Is there any solution to fix this?
    Thank you very much.

    My device : iPhone X iOS 12.3.1

  3. I’m playing Pokémon Fire Red, and it keeps crashing in 5-10 minute intervals. I’m tired of having to backtrack. Please fix this.

  4. running v0.8 and ios 12.4 iphone x
    crashes also after about 5 mins , n64 or snes games
    any ideas on solution or when an update is due ?

  5. So I’m having an issue where I’ll play a game for about 5min and then it crashes. I tried multiple games to figure out if it was a specific one or not. But it happens on all and all the consoles. Is there an update coming out soon for this fix?

  6. Game installs and plays without error up to 30 seconds then app closes. This is using iPhone 6 Plus with iOS 12.4. Any solution

  7. Hi, for me my delta emulator will not open because it says unable to verify app. This happened a bit after I had been playing for a while and whenever I try to verify it in settings it doesn’t work.

  8. Had it downloaded and it was working fine and then today on lunch it said i had to verify the app so I did and it just wouldn’t open at all after that.

  9. Downloaded Delta in my iOS 13.2.3 (Iphone SE) (Not Jailbreak)
    Downloaded Resident Evil 2 ROM, the main screen works but
    into the actual gameplay it doesnt show the characters but the inventory screen works perfectly fine, this made me worry, any fix?

  10. When I boot it up, it crashes before even getting past the logo. I am an SM64 Machinmist so this is very troubling as I cannot run my channel without a safe Emulator capable of running SM64 on iOS.

  11. My delta emulator won’t even open when I tap on it it shows the sign and sends me right back to the main screen and I have tried everything from reinstalling it to turning my device off

  12. As soon as i open the app, it closes it directly. I tried all the solutions but none helped me? I’m willing to pay to get it fixed tho….

  13. Ds ROMs will load but not having a .sav file stops me from playing, any help? ROMs load without issue and show in library but can’t play. Otherwise no issues for GBA/GBC ROMs 🙂

  14. So I’ve successfully downloaded and played one game on delta but no matter what roms I try from any site I cannot get a second one to work the rom downloads and converts from .zip to .gba/nds/etc and the file gets the delta icon but it refuses to actually open and play in the delta app, I really enjoyed playing the first game so if there’s any fix it would be appreciated

  15. Try fix the save state. That when you load the state where you save, it become crashed so pls fix the save state it can sometimes happen if the error coding when saved after when you leave the app.
    And add log so to see a error log.

  16. When using delta with airplay and a controller connected on the DS emulator then the second screen of the DS (the touch area) disappears completely which doesnt let you play the games.
    If you dont connect to a controller then you can see the second screen and controls on the phone and only the main screen is being broadcasted to the airplay device.

  17. When I load save files that were used in Drastic on Android, I encounter errors.

    While some save files import successfully, others result in errors.
    For example, this issue occurs with the game ‘Kirby: Squeak Squad.’
    Even changing the file extension from ‘dsv’ to ‘sav’ doesn’t resolve the problem. Is there a way for me to fix this?”

  18. Hey so there’s currently a problem with the n64 emulator where it doesn’t seem to regocnise tilting left on R3 with the backbone, I know it isn’t just the left c-button that’s the problem because I tried mapping it so somewhere else and it worked as well as mapping another button to left tilt R3 and the left tilting doesn’t seem to work. I also know the stick isn’t broken because it recognises when I tilt left with R3 it registers when I map buttons, so I think it would good to look into it in case it’s also affecting other controllers.

    • Also when I tried to send this to your “contact us”, the CAPTCHA Wouldn’t show me the image so I can’t send it to your mail seemingly so Idk if that’s something you guys can fix or what but I figured that I’d tell you that.

  19. Ahoi there! I noticed a critical issue that prevents me from playing for example Super Mario World and other games alike which might not be obvious to the average user at first: When you are holding the “Y” button in order to run faster and then hit the “B” button to jump while simultaneously still holding down the Y button at the the same time, the emulator acts as if the Y button was released when the B button was pressed and as soon as the B button is released again it re-presses the Y button. This leads to for example not being able to “hold” the red turtle shells while running fast and jumping and so on. It also leads to Yoshi always snapping his tongue once you try to run fast and jump and so on. I hope I could explain what I mean :D. Same with Contra. You should be able to hold down the “fire” button while at the same time being able to jump. I would even go as far as deeming this a game breaking bug if you try to play any of these two classic games seriously in Delta. I am also startled that nobody else has noticed this till now, since I literally came across this problem the first 10 seconds of playing. The solution would be to let multiple buttons be pressed at the same time and also released individually without influencing the other buttons. Thank you very much for your efforts and the awesome app! Love it! All the best 🙂 !
