 2) What is Hatari?
 ------------------

Hatari is an Atari ST/STE/TT/Falcon emulator for Linux, FreeBSD, NetBSD, macOS,
Windows and other Systems which are supported by the SDL2 library. Unlike most
other open source ST emulators which try to give you a good environment for
running GEM applications, Hatari tries to emulate the hardware as close as
possible so that it is able to run most of the old Atari games and demos.


 3) Compiling and installing
 ---------------------------

To build and use Hatari, you first need to install its dependent libraries.


 3.1) Installing Hatari dependencies

Required:
- The SDL library v2.0.6 or newer (http://www.libsdl.org)

Optional:
- The zlib compression library (https://zlib.net/)
- The PNG image library for PNG format screenshots and to decrease
  AVI video recording file sizes (http://www.libpng.org/)
- The GNU Readline library for Hatari debugger command line editing
- The Xlib library to support Hatari Python UI window embedding on
  systems with the X window system (Linux and other unixes)
- The PortMidi library required for MIDI device support on macOS and Windows
  (http://portmedia.sourceforge.net/)
- The udev library for NatFeats SCSI driver media change detection
- The IPF support library
  (http://www.softpres.org/download & https://www.kryoflux.com/?page=download)
- The Capstone library (version >= 4.0) for traditional disassembly output
  in the debugger (https://www.capstone-engine.org/)

Don't forget to also install the header files of these libraries for compiling
Hatari (some Linux distributions use separate development packages for these
header files)!

For compiling Hatari, you need a C compiler that supports the C99 standard
(preferably GNU C or Clang), and a working CMake (v3.3 or newer) installation,
see http://www.cmake.org/ for details.

On RedHat based Linux distributions, you get (most of) these with:
	sudo dnf install gcc cmake SDL2-devel zlib-devel libpng-devel \
	  readline-devel

And on Debian/Ubuntu based ones with:
	sudo apt install gcc cmake libsdl2-dev zlib1g-dev libpng-dev \
	  libreadline-dev


 3.2) Configuring and compiling

CMake can generate makefiles for various flavours of "Make" (like GNU-Make)
and various IDEs like Xcode on macOS. To run CMake, you have to pass the
path to the sources of Hatari as parameter. For example, run the following
command sequence to configure the build of Hatari in a separate build directory
(assuming that the current working directory is the top of the source tree):

	mkdir -p build
	cd build
	cmake ..

Have a look at the manual of CMake for other options. Alternatively, you can
use the "cmake-gui" program to configure the sources with a graphical
application or "ccmake" to configure them with ncurses UI.

For your convenience we also ship an old-fashioned configure script which can
be used as a wrapper for running cmake. Type "./configure --help" to see the
options of this script.

Once you have successfully configured the build settings, you can compile
Hatari with:

	cmake --build . -j$(getconf _NPROCESSORS_ONLN)

If all works fine, you should get the executable "hatari" in the src/ sub-
directory of the build tree. You can then either run the executable from
there, or install the emulator system-wide by typing:

	cmake --install .

Note: This only works with CMake version 3.15 and later. On earlier versions,
you have to use the install command of the generator program instead, e.g.
"make install" if you are using the classical "make" for building Hatari.

 3.2.1) Configuring and compiling with emscripten

	mkdir -p build/files
	# Copy your tos.img to build/files/
	cd build
	emcmake cmake ..
	cmake --build . -j$(getconf _NPROCESSORS_ONLN) hatari

The resulting hatari.html can't be used directly, you must provide it via
a webserver to your browser (use Chromium, it currently works better than
Firefox). A simple way is to use "python3 -m http.server" as a minimalist
webserver for testing it locally.


 3.3) IPF support using capsimage library

While Hatari has built-in support for IPF images, the related code is
still experimental and cannot load all types of IPF images. Thus
Hatari can use the optional capsimage library to access IPF and CTR
files. Those files are created using the Kryoflux board and allow to
record MFM exact copies of original games, including the protection.

Hatari supports version 5.1 of the library (previous support for older
version 4.2 was removed as it is not used anymore)

Refer to the "User Distribution" section on http://softpres.org/download or
the "SPS Decoder Library" section on https://www.kryoflux.com/?page=download
and get the corresponding file that matches your OS.

For version 5.1, you should have the following files in your include path :
/usr/local/include/caps/
	CapsAPI.h
	CapsFDC.h
	CapsForm.h
	CapsLibAll.h
	CapsLib.h
	CapsLibVersion.h
	ComLib.h
	CommonTypes.h

You should also copy the libcapsimage.so* files in your library path,
for example in /usr/local/lib/caps/


 3.4) Notes for Linux distribution packagers

TOS tester in tests/tosboot/ directory can be used to verify that
Hatari was built fine enough that it's able to boot all tested TOS
versions in various different HW configurations and run some GEMDOS
based tests.  For EmuTOS, use the latest released 1024k version to
get best test coverage.

If Hatari package will have two application menu entries for Hatari,
one for the Python UI embedding Hatari, and another one for the plain
SDL version, the latter could open also a terminal window for Hatari
command line debugger and its console messages:
x-terminal-emulator -T "Hatari debugger, invoke with AltGr+Pause" -e hatari

tools/hatari-tos-register.sh is a minimal example of Linux init script
registering Hatari as a (binfmt_misc) handler for TOS binaries.

Alternatively one could add a mime type for TOS binaries with xdg-mime:
  http://portland.freedesktop.org/xdg-utils-1.0/xdg-mime.html
But registering handlers for mime-types seems desktop specific.


 4) Running Hatari
 -----------------

For information about how to use the running emulator, please read the file
doc/manual.html. Here are just some hints for the impatient people:

* Before you can run the emulator, you need a TOS ROM image.  If one
  named as "tos.img" is neither in the data directory of the emulator
  (DATADIR variable in CMake configuration), or in the current
  directory, Hatari will ask you to select one.

  - Hatari binary packages ship unmodified EmuTOS ROM image with them
    (renamed as tos.img), but you may need an original Atari TOS ROM
    image for better compatibility.  For more information on EmuTOS,
    see doc/emutos.txt.

* While the emulator is running, you can open the configuration menu
  by pressing F12, the F11 key will toggle fullscreen/windowed mode.
  Pressing ALTGR-q will quit the emulator.


 4.1) Known Windows (SDL) issues

On Windows, Hatari console output doesn't go to console like on other
platforms. This is because Windows SDL v2 library discards all that
output by default.

To see Hatari help/warning/trace output, and to interact with Hatari
debugger, there are two options:
- Run Hatari with "-W" option, or
- Compile Hatari with "-mconsole" option (as last --linker flag) to
  build Hatari for the Windows console subsystem

Because these cause separate console output window to be opened (in
addition to the Hatari window), they are not enabled by default. 


 5) Hatari tools and their run-time dependencies
 -----------------------------------------------

While Hatari installs few binary tools binaries:
- hmsa (converts between MSA & ST disk images)
- gst2ascii (outputs debug symbol table contents for Atari binaries)

Most of its tools are Python and shell scripts.
Their main run-time dependencies are:
- python (hatariui, hconsole, hatari_profile, atari-convert-dir)
- python & gtk3 (hatariui)
- mkdosfs (atari-hd-image)
- mtools (atari-hd-image / zip2st)
- unzip (zip2st)
