You can run VCMI on iOS 12.0 and later, all devices are supported. If you wish to run on iOS 10 or 11, you should build from source, see How to build VCMI (iOS).
The easiest and recommended way to install on a non-jailbroken device is to install the AltStore Classic or Sideloadly. We will use AltStore as an example below. Using this method means the VCMI certificate is auto-signed automatically.
i) Use AltStore Windows or AltStore macOS instructions to install the store depending on the operating system you are using.
If you're having trouble enabling "sync with this iOS device over Wi-Fi" press on the rectangular shape below "Account". Windows example from iTunes shown below:
ii) Download the VCMI-iOS.ipa file on your iOS device directly from the latest releases.
iii) To install the .ipa file on your device do one of the following:
If you bought HoMM3 on GOG, you can download the files directly from the browser in the device.
Launch VCMI app on the device and the launcher will prompt two files to complete the installation. Select the .bin file first, then the .exe file. This may take a few seconds. Please be patient.
Once you have installed VCMI and have the launcher opened, select Settings on the left bar. The following Video settings are recommended:
Together, the two options should eliminate black bars and enable full screen VCMI experience. Enjoy!
To run on a non-jailbroken device you need to sign the IPA file, you have the following aternative options:
your.bundle.id with something like com.MY-NAME.vcmi. After that use the above signer tool.The easiest way to install the ipa on your device is to do one of the following:
Alternatively, to install the signed ipa on your device, you can use Xcode or Apple Configurator (available on the Mac App Store for free). The latter also allows installing ipa from the command line, here's an example that assumes you have only 1 device connected to your Mac and the signed ipa is on your desktop:
/Applications/Apple\ Configurator.app/Contents/MacOS/cfgutil install-app ~/Desktop/vcmi.ipa
Note: if you don't need in-game videos, you can omit downloading/copying file VIDEO.VID from the Data folder - it will save your time and space. The same applies to the Mp3 directory.
To play the game, you need to upload HoMM3 data files - Data, Maps and Mp3 directories - to the device. Use Finder (or iTunes, if you're on Windows or your macOS is 10.14 or earlier) for that. You can also add various mods by uploading Mods directory. Follow official Apple guide and place files into VCMI app. Unfortunately, Finder doesn't display copy progress, give it about 10 minutes to finish.
If you have data somewhere on device or in shared folder or you have downloaded it, you can copy it directly on your iPhone/iPad using Files application.
Place Data, Maps and Mp3 folders into vcmi application - it will be visible in Files along with other applications' folders.
You can also upload files with Xcode. You need to prepare "container" for that.
You can start game directly (avoiding the launcher) by changing setting in iOS Settings app - VCMI.
