+# ScummVM for iOS 7.1+ #
+
+This is a quick fix of the latest ScummVM (1.8.0) for iOS 7.1. It has been tested on real iPhone 6S+, and iPad Pro, and also on all the available Xcode simulators.
+
+I tried to use all the latest iOS features to replace the old code. For instance, it uses gesture recognizers most of the time, it supports the new iPhones 6 / 6+ / 6s / 6s+ resolution, and you can copy your game files using iTunes.
+
+## Compilation ##
+
+First, clone the repository:
+```
+$ git clone -b ios-fix --recursive https://github.com/bSr43/scummvm.git
+```
+
+### Compilation from Xcode ###
+
+This is the recommended way to compile ScummVM, and the only one which makes it possible to run ScummVM on a non-jailbroken device!
+
+The next step is to compile the **create_project** tool. Open the Xcode project you'll found in the **devtools/create\_project/xcode/** directory. Once compiled, copy the binary somewhere in your *PATH*, and create a **build** directory somewhere on your harddisk. It is recommended to create this directory next to the cloned repository (they share the same parent).
+
+Execute the following commands in a terminal:
+```
+$ cd path_to_the_build_directory
+$ create_project path_to_scummvm_repository --xcode --enable-fluidsynth --disable-jpeg --disable-bink --disable-16bit --disable-mt32emu --disable-nasm --disable-opengl --disable-theora --disable-taskbar
+```
+
+This will create an Xcode project for ScummVM, for both the OS X, and the iOS target.
+
+Now, download the external libraries from http://bsr43.free.fr/scummvm/ScummVM-iOS-libraries.zip. Unzip the archive in your **build** directory. Please make sure that the **lib**, and **include** directories are at the root of the **build** directory, not in a subdirectory.
+
+Now, your **build** directory should contain:
+* a generated **engines** directory,
+* a generated **scummvm.xcodeproj** project,
+* an **include** directory,
+* a **lib** directory.
+
+You are ready to compile ScummVM: open the **scummvm.xcodeproj** project, and build it.
+
+### Compilation from command line ###
+
+For jailbroken devices, it is also possible to compile the project from command line. You'll need a working toolchain, and some tools, like **ldid**, to fake the code signature.
+
+Here is a script to download, and compile all the required tools. This script has been wrote for Debian 8.2, and should be run as root.
+
+```
+#!/bin/bash
+
+if [ $UID -ne 0 ]; then
+	echo "This script should be run by the root user"
+	exit 1

+
+Now, in order to compile ScummVM, execute the following commands:
+```
+$ export SDKROOT=/usr/share/ios-sdk/iPhoneOS8.1.sdk
+$ export CC=ios-clang
+$ export CXX=ios-clang++
+$ ./configure --host=ios7 --disable-mt32emu --enable-release
+$ make ios7bundle
+```
+
+At the end of the compilation, you'll find a **ScummVM.app** application: copy it over SSH, and reboot your device.
+
+## Usage ##
+
+The game data files can be copied on the iOS device using iTunes. Once done, add your games in ScummVM as usual.
+
+Here is a list of the in-game gestures:
+
+|Gesture|Description|
+|-------|-----------|
+|Two fingers swipe down|Display the ScummVM menu for loading, saving, etc.|
+|Two fingers swipe right|Enable / disable the touchpad mode|
+|Two fingers swipe up|Enable / disable the mouse-click-and-drag mode|
+|Two fingers tap|Simulate a right click. You should tap with one finger, and then tap with another while keeping your first finger on the screen.|
+|Two fingers double-tap|Skip the cinematic / video|
+
+The iOS keyboard is visible when the device is in portrait mode, and hidden in landscape mode.
