Frequently Asked Questions:
As with any app, there are always some questions that get asked frequently:
- How Do I Install Delta Emulator?
Not from the iOS app store. Right now, Delta is in closed beta and, as such, there isn’t a way of downloading it from the Apple AppStore. Right now you can download it from the links above on the Emus4U appstore.
- Is My Device Supported?
Delta Emulator is supported on all iOS devices on iOS 10 or above, and the app has been specially optimized to support the iPhone X series of devices.
- What About Adding Games to the Emulator?
Right now, there are three ways to do this:
- Open any web browser on your iPhone or iPad
- Open a search engine and look for the game ROM’s you want to download ( what is a ROM ) make sure it is from a reputable site
- Download it and, when it has completed, find and right-click the file
- Select Open With and choose Delta; the game will open in Delta Emulator
- Download any ROM you want onto your computer
- Connect your iPhone or iPad to your computer and then open iTunes
- Choose your device and then click on Apps (top of the screen)
- Click File Sharing and then click on Delta
- Drag the games you want into Delta
- Open Delta and click on Add ( top-right ); choose iTunes as your import source
If you have Delta ROMS already stored in Dropbox, Google Drive or any other cloud storage, you can enable syncing on your iPhone or iPad; any ROMs, cheats, saves and save states will automatically download.
- My ROM Won’t Import Properly, What Do I Do?
Riley Testut has produced a guide on each system, and you can check it out here. If all the guidelines are met and the ROM still won’t import, there is a good chance the ROM is corrupted. Find a new source an make sure that the ROM has been correctly zipped – it should only be the ROM, not a folder that contains it.
- Can I Delete Games?
Yes. Find the ROM image that you want deleting and long-press on it; tap on delete and confirm on the popup window. This will not remove any ROMS that may be stored in cloud storage.
- How Do I Transfer Files Between my Computer and Device?
Quite easily, but be aware that only ROMS and save states will work with another emulator.
- Connect your device to your computer and open iTunes
- Click on your device and then click Apps
- Click File Sharing > Delta and drag the Database folder onto your desktop – this is where all your data is
- Will I Lose my Data If I Delete Delta?
Yes. Copy all your data into the Database folder on your desktop and then reinstall the app; the data can be dragged back to it. If cloud syncing was enabled when you delete the app, any data stored in the cloud is safe and, if you reinstall Delta, you can sync it.
- How Do I Switch Fast Forward on?
While you are playing any game, tap Menu and tap Fast Forward; alternatively, if you have a keyboard or MFi controller connected, configure a button so fast forward is enabled when you hold it down.
- What About Sustaining a Button?
Again, while in gameplay, tap on Menu>Sustain Button. The controller will come up, and you can choose the button. If you are using an MFi controller, configure any button to go into Sustain mode when it is pressed. Then tap on the button you want to sustain or press where there is no button if you want to cancel it.
- I want to Change the Graphics Filters – How Do I Do It?
There is no support for this yet; it is expected in a future update
- Can I Use My iPad?
Yes. Delta has full support for the iPad and also for the split-screen view so you can multitask efficiently.
- I Want to Link Two Devices so I Can Trade – Is This Possible?
This is not yet supported, but saves can be transferred to your desktop and then linked together. Use a program like VBA-Link to do this. We expect this feature in a future update.
- How Do I Create Save States?
When you are playing, tap on Menu>Save State. A new menu will appear, tap on any General save state if you want to overwrite it or, to add a new one, tap on the Plus button. To identify the save state, a time signature and snapshot of the game is also saved. You cannot override autosaves or locked save states.
- How Do I Load Save States?
In gameplay, tap on Menu > Load State. Choose the state you want to load, and the game will start at that point. If you force-touch on a game and swipe up, you can load the most recent save state. Long-pressing and tapping on the Save States will allow you to load a specific state.
Note: when you do this, an autosave state is created, allowing you to go back to where you were if the load was an error. Plus, no changes are made to your save file when you load or create save states, so make sure you save when you can.
- Can I Give Save States a New Name?
Yes. When you are playing, tap on Menu > Save or Load State. Tap and hold on a state (not an autosave) and tap Rename on the new menu. Type the name and tap Rename. You can do the same thing from the main menu in Delta by long-pressing a game.
- Can the Save States be Protected From Accidental Overwrites?
Yes. Follow the steps for renaming a save state and, when the menu appears, tap on Lock/Unlock. Tap on Lock, and the state is moved to that section. These cannot be overwritten but can still be loaded or deleted. To unlock, tap, and long hold on a state and tap on Unlock.
- How Do I Get Into the Cheat Menu?
During gameplay, tap on Menu > Cheat Codes.
- How Do I Enable or Disable Cheats?
When you bring up the Cheats menu, you can toggle each individual cheat on or off by tapping it
- What Cheats Are Supported?
Riley Testut has drawn up a list of the accepted cheats, and you can find them here.
- How is Syncing Enabled?
From the Delta main menu, go into Settings and tap on Cloud Syncing. Then tap on Enable Syncing. Delta gives you the choice of signing into Google Drive or Dropbox; choose and sign in, and your data will be synced to your cloud service.
- After I Enable Syncing, My Games are All Marked as Conflicted – Why?
Because there is already a save file for the game in your cloud drive. Delta cannot tell which save the file you want to use, so it marks it as conflicted, and syncing is disabled. That way, the right file doesn’t get written over accidentally.
- How Do I Remove a Conflict?
Open the Syncing menu and tap on the game name. A new view loads showing you the local and any cloud files for the game. Choose one to use on all devices and then toggle on the switch (top of the screen). The save file will be synced to all devices and syncing re-enabled.
- Can Syncing Be Enabled or Disabled for an Individual Game?
Yes. Open the Syncing menu and choose the game you want syncing enabled or disabled for. Tap it and toggle the switch on the new view off.
- Can I Sync to More Than One Cloud Service?
No, this is not supported at the moment. It may be added in a future update.
- I Chose The Wrong Save File for Syncing on a Conflicted Game. How Do I Restore the Previous File?
Open the Syncing menu and choose the game you want to be reverted to a previous save file. On the net window, choose the version you want to sync with.
- How Do I Change Skins?
Yes, you can customize and add new skins to the controllers. We have a detailed step by step guide to download and install Delta Emulator Skins.
The development team for Delta Emulator does not condone piracy in any way. It is illegal to download any ROM from the internet, and we urge you to buy your own games and dump them. The legality, or otherwise, may also include downloading ROMS for games that you already purchased.
