+
+
+
+1.0) Installation
+-----------------
+There are two possible formats to be used: 3DSX and CIA (recommended).
+The 3DSX format is exclusively used by the Homebrew Launcher and its derivatives.
+The CIA format can be installed directly to the 3DS home menu and can be launched
+using any CFW (Custom Firmware) of your choice.
+
+Installing the Homebrew Launcher or any CFW is beyond the scope of this README.
+Look elsewhere to see how to install those if you do not already have them set up.
+
+
+1.1) 3DSX installation
+----------------
+The CIA format is recommended for stability and maximum game support. If that is
+not an option, you will need one of a collection of 3DS titles installed on your
+system in order to properly launch ScummVM as a 3DSX. This is because the
+Homebrew Launcher hijacks other processes to run 3DSX homebrew, and ScummVM is a
+particularly large homebrew that can't be launched with the resources provided
+by standard system applications.
+
+You will need one of the following (installed or physically in cart slot):
+
+- Youtube
+- Monster Hunter 4 Ultimate Special Demo
+- Monster Hunter 4 Ultimate
+- Monster Hunter 4G
+- Super Smash Bros. for Nintendo 3DS Demo
+- Super Smash Bros. for Nintendo 3DS Special Demo
+- Super Smash Bros. for Nintendo 3DS
+
+Once you have one of the above, you need to merely extract all ScummVM 3DS files
+to the root of your SD card so that all files reside in the /3ds/scummvm/ directory.
+
+
+1.2) CIA installation
+---------------------
+The CIA format requires a DSP binary dump saved on your SD card as /3ds/dspfirm.cdc
+for proper audio support. You can search online to find software to dump this.
+Not having this file will cause many problems with games that need audio, sometimes
+even crashing, so this is NOT considered optional.
+
+Using any CIA installation software (search elsewhere for that), you need to install
+the scummvm.cia file. Then, just like what is done with the 3DSX installation, you
+need to extract all ScummVM 3DS files (scummvm.cia excluded) to the root of your SD
+card so that all files reside in the /3ds/scummvm/ directory.
+
+
+
+2.0) Controls
+-------------
+
+2.1) Default key mappings
+-------------------------
+The D-Pad and A/B/X/Y buttons have mirrored usage. So they do the same things
+depending on if you're right or left-handed.
+
+| Buttons | Function |
+|------------|--------------------------------|
+| A / D-left | Left-click |
+| X / D-up | Right-click |
+| B / D-down | ESC (skips cutscenes and such) |
+| L | Use virtual keyboard |
+| R | Toggle hover/drag modes |
+| Start | Open game menu |
+| Select | Open 3DS config menu |
+| Circle Pad | Move the cursor |
+
+
+2.2) Hover mode
+---------------
+When you use the touchscreen, you are simulating the mere moving of the mouse. You
+can click only with taps, meaning it is impossible to drag stuff or hold down a
+mouse button without using buttons mapped to right/left-click.
+
+
+2.3) Drag mode
+--------------
+Every time you touch and release the touchscreen, you are simulating the click and
+release of the mouse buttons. At the moment, this is only a left-click.
+
+
+
+3.0) Supported Games
+--------------------
+The full game engine compatibility list can be found here:
+http://scummvm.org/compatibility/
+
+While all the above games should run on the 3DS (report if they do not), there are
+many games which are unplayable due to the lack of CPU speed on the 3DS. So if
+you play any games that run really slow, this is not considered a bug, but rather
+a hardware limitation. Though possible GPU optimizations are always in the works.
+The New 3DS console has much better performance, but there are still many newer and
+high-resolution games that cannot be played. A list of these unplayable games and
+game engines will eventually be listed here.
+
+
+
+4.0) Compiling
+--------------
+
+4.1) Prerequisites
+------------------
+ - devkitARM (presumably with libctru, picasso and such)
+ - citro3d
+ - Optional: You should compile third-party libraries for the 3ds (commonly referred
+ to as portlibs in the devkitPRO community). Some games requires these to operate
+ properly.
+
+
+4.1.1) Compiling third-party libraries
+--------------------------------------
+Most libraries used can be compiled with same commands and configuration flags.
+
+It is assumed that you have these environment variables defined:
+ - DEVKITPRO Your root devkitPro directory
+ - DEVKITARM Your root devkitARM directory (probably same as $DEVKITPRO/devkitARM)
+ - CTRULIB Your root libctru directory (probably same as $DEVKITPRO/libctru)
+
+In the source directory of the library:
+ - $ export PORTLIBS=$DEVKITPRO/portlibs/armv6k
+ - $ export PATH=$DEVKITARM/bin:$PATH
+ - $ export PKG_CONFIG_PATH=$PORTLIBS/lib/pkgconfig
+ - $ export CFLAGS="-g -march=armv6k -mtune=mpcore -mfloat-abi=hard -O2
+ -mword-relocations -ffunction-sections -fdata-sections"
+ - $ export CPPFLAGS="-I$PORTLIBS/include -I$CTRULIB/include"
+ - $ export LDFLAGS="-L$PORTLIBS/lib"
+ - $ mkdir -p $PORTLIBS
+ - $ ./configure --prefix=$PORTLIBS --host=arm-none-eabi --disable-shared
+ --enable-static
+ - $ make
+ - $ make install
+
+Useful libraries (and special config flags needed):
+ - zlib
+ - libpng
+ - libjpeg
+ - freetype2 --without-bzip2 --without-harfbuzz
+ - libmad
+ - tremor
+ - flac --disable-cpplibs --without-flac
+ - faad
+
+
+4.2) Compiling ScummVM
+----------------------
+ - $ ./configure --host=3ds
+ - $ make
+
+Additionally compile to specific formats to be used on the 3ds:
+ - $ make scummvm.3dsx
+ - $ make scummvm.cia
+
+
+4.3) Warning for 3DSX build
+---------------------------
+The above configuration command will include all game engines by default and will
+likely be too massive to run using the 3DSX format. Until dynamic modules are figured
+out, you should configure engines like this for 3DSX builds:
+
+ - $ ./configure --host=3ds --disable-all-engines--enable-engine=scumm-7-8,myst,riven,
+ sword1,sword2,sword25,sci,lure,sky,agi,agos
+
+Choose whatever engines you want, but if the ELF's .text section exceeds ~10MB, it
+won't be playable unless it's a CIA.
