 COMPILE
 =======

   Define AUDIO_CALLBACK if you want to use the older audio API using
   callbacks (pre-2.0.4 versions of SDL2 only support this one).

   Define explicitly ZIP_SUPPORT in case you need preliminary ZIP file
   support - only used for opening compressed D64 files for now.

   GNU
   ---

   To be able to compile on Linux, you must have the latest SDL
   package from http://libsdl.org. The recent stable release as of time of
   this writing is 2.0.4. You will also need the development libraries.

   The provided makefile is written for the GNU C++ compiler but can also
   be easily adjusted for other compilers.

   It is very likely that if SDL and GCC are supported on your system, then
   Yape can be compiled and run. Hence, an Android port is also possible,
   and Yape has been succesfully compiled on Windows and 64 bit Linux systems
   as well.

   Once the libraries and header files are installed, you should
   extract the source tarball to a directory, and simply type:

   make

   Alternatively, you can use the provided Code::Blocks project
   file to compile Yape.

   If the compilation finished with no error, you can type:

       ./yapesdl [PRG/P00/T64/TAP/D64/ZIP filename] [-c64]

   to start the emulator, where [] means optional arguments.

   Windows
   -------

   Make sure you install either the Visual Studio or the Mingw version
   of the SDL development library. You can use either compiler
   targeting 32 as well as 64-bit binary builds.

   Note that the 2.0.4 version of the Windows SDL runtime library has a
   serious crash in its DX9 driver. The one included in the Windows
   yapesdl binary package is a bugfixed build.

   Emscripten
   ----------

   Compiling for Emscripten (Javascript) requires a lot of ugly manual
   workarounds. These will be documented at a later stage.

   Under Windows it's best to use the official package that is embedded
   into Visual Studio 2010.

   You might also need to download SDL2 headers separately from here:
   https://github.com/kripken/emscripten
   https://github.com/emscripten-ports/SDL2

   Also download the prebuilt SDL2 libraries required for linking:
   https://buildbot.libsdl.org/sdl-builds/sdl-emscripten/?C=M;O=D

 USAGE
 =====

   The user interface isn't yet ready, so you MUST memorise a couple
   of keyboard shortcuts:

   F12 or ESCAPE : exits the emulator
   F11		: soft reset
   LCTRL + F11	: forced reset (memory remains intact)
   SHIFT + F11	: hard reset (clear memory, reloads ROMs, rewinds tape)

   F5		: press PLAY on tape
   F6		: press STOP on tape
   F7		: save screenshot to BMP file
   F8		: enter the user interface, press F8 again or ESC to quit.
               You can move around in the menus with the arrow keys, press ENTER for selection.
   F9		: quick debugger
   F10		: save current settings to user's home directory

   LALT + 1-3   : set window size
   LALT + L	   : switch among emulators (C+4 cycle based; C+4 line based; C64 cycle based)
   LALT + I	   : switch emulated joystick port
   LALT + M     : enter console based external monitor and disassembler
   LALT + P	   : toggle CRT emulation
   LALT + R     : machine forced reset
   LALT + S     : display frame rate on/off
   LALT + W	   : toggle between unlimited speed and 50 Hz frame rate (original speed)
   LALT + ENTER : toggle full screen mode
   LALT + F5    : save emulator state
   LALT + F6    : load emulator state
   LALT + F8	   : save memory pointed by $2B/$2C and $2D/$2E
   LALT + KPLUS : collate replay frequencies

   Internal disk LOAD/SAVE operations are supported to the current
   file system directory - which is usually '/home/<username>/yape'.
   Any PRG files you may wish to load, should go there, although you can browse the directory tree
   from the user interface, too.

   This means that an exact filename match will load
   the requested program, similarly can you save a file.

   Full ROM banking is supported, currently only via the yape configuration
   file. You must fill in the path for the relevant ROM image you intend to use.
   However, Yape supports some internal ROMs already. These are:

   - 'BASIC' 	 - the ROM image containing the BASIC interpreter
   - 'KERNAL' 	 - the system kernal ROM image
   - '3PLUS1LOW'  - the low bank ROM image of the built-in plus/4 software
   - '3PLUS1HIGH' - the high bank ROM image of the built-in plus/4 software

 KEYBOARD MAPPINGS
 =================

   For the keys at different positions, the emulator relies on SDL, so your
   mileage may vary.

   There are a few keys that need to be mapped to the emulator keyboard
   differently. These are:

   Commodore       emulator
   ------------------------
   Pound 	= END
   Clr/Home	= HOME

 FEATURES
 ========

   YapeSDL features:

   - full, cycle exact MOS 6502/6510/7501/8501 CPU emulation
   - almost full MOS 7360/8360 aka 'TED' chip emulation
   - almost complete MOS 6569 aka 'VIC-II' chip emulation
   - reasonable MOS 6581/8580 aka 'SID' chip emulation
   - somewhat incomplete CIA 6526 aka 'CIA' emulation
   - real 1541 drive emulation (Read/Write)
   - full ROM banking on +4
   - almost full tape emulation (+4 for now)
   - joystick emulation via cursor keys and gamepads
   - PRG, P00, T64, D64 and TAP file format support
   - partial CRT emulation
   - disk LOAD/SAVE to the file system on +4
   - snapshots / savestates
