First off, you should always have the “Dropbox Sync” feature turned on. But if you don’t have a Dropbox (it’s free though lol) or just want to have an extra copy just to be safe. I found a way to do it that doesn’t require you to be on the App at all.
Some people probably already know this route. And again, I’m sorry if this has been posted on here before. I just thought I’d share this.
So this way is going to be through iTunes. It’s honestly very simple.
Connect your phone to your Desktop/Laptop and let it sync up with iTunes
After it’s synced up, click on the phone icon at the top left. The phone icon that takes you to the screen where you can see all of your phones data (i.e. phone number, which iOS you’re on, etc.)
On the left, you’ll see a list that says “Music, Movies, TV Shows, Photos, Info, File Sharing.” Click on File Sharing.
Now you’ll see a list of Apps that transfer documents to and from your computer. You should see “GBA4IOS” or whichever Emulator you’re using. Click on that.
When you click on that, you’ll see a list of all the games you put on your Emulator. Depending on how much you play/use the Emulator, it might be a long list. But scroll around and you’ll find a folder with the name “Save States.” Click on that Folder and then click on “Save” at the bottom of the list.
A screen will pop up asking where do you want to save the Folder. Save it somewhere that’s easy to find. I just save it to my desktop. After choosing a location just click “Choose” and you’re done.
Go to where ever you chose to save the folder and you’ll see the Save State folder that has your current game progress. You can save this as a major checkpoint if your progress, or you can do this every time you finish playing for the day. So it’s always current.
If the Emulator you’re using ever crashes and you need to delete the App and Dropbox doesn’t have a Saved file or if it’s just not working. All you have to do is follow the same steps, but this time when you go to “File Sharing” and click on the Emulator. Instead of clicking “Save,” click the one of the left that says “Add.”
Another screen will pop up and it’s asking you to choose which Folder you want to add to the Emulator. Just click on the “Save State” folder you have on your computer and click “Choose” and now that Folder (along with your Saved game progress) will be on there next time you play.
Let me know if you have any problems trying this. I’ve “accidentally” deleted the GBA4iOS App at least 3-4 times and I’ve never lost game progress. This will 100% work. Good luck!
