 Contributors:
 -------------

Following people contributed code or patches to this projects and/or
helped to find bugs in Hatari (listed in random order - and if someone
is missing here, please remind me!):

- Jean-Baptiste Berlioz <tobe at freemind-tobe.com> : Cycle accurate
  Blitter emulation.

- David Savinkoff : More accurate printer emulation, LMC1992 emulation
  patches, IIR/Low Pass filters and many improvements to the YM2149 model
  to get a close emulation of the circuit used to merge and filter the
  output of the 3 YM2149 voices.
  Great work to enhance the sound quality.

- Matthias Arndt <marndt at asmsoftware.de> : Wrote the original version
  of the Hatari user manual, fixed the printer emulation functions.

  "man" page of Hatari and maintained the Hatari Debian packages until
  Hatari was included into Debian.

  running many tests programs and providing the source code for some
  non-working demos.

  and options for controlling how the output looks.

- Deniz Turkoglu: Patches for the Max OS X GUI.

- Markus Heiden: SCSI class 1 (ICD) command support for drives > 1 GB

- nash67: tested hundreds (!) of games from various CD compilations
  and reported the non working ones on atari-forum.com. Huge thanks for
  that tedious work, it helped tracking down some less common cases
  not used in demos (keyboard, joystick, FDC, tos, ...).

- Gilles Fetis: fixes to MMU emulation (from NeXT emulator project
  using Hatari code).

- Peter Putnik (Petari, AtariZoll): Helped tracking the
  cause of the crash in Microprose Golf (FDC emulation). Also wrote
  some useful tools to handle floppies (flofor, floimg), as well as
  opcovat.tos to report valid/invalid opcodes with a real CPU and
  under emulation by testing all possible opcode combinations.

- Jean Louis Guerin (DrCoolZic): 'Panzer' program, very useful
  for testing some FDC behaviours and timings on real hardware and to
  compare them with the emulated system. Also wrote some nice docs on
  WD1772 and methods commonly used for games' protections.

- Christer Solskogen: Set up an automatic build script on his site,
  providing up to date Hatari binaries for Linux and Windows in 32
  and 64 bit mode. Very useful for end users wishing to try the devel
  versions of Hatari, and lots of interesting build logs too for
  various cpu architectures. See http://antarctica.no/~hatari/latest

- Max Böhm: host <-> Atari filename encoding conversion routines and
  related changes needed to gemdos.c.

  accuracy, tested & gave feedback on Hatari CPU & DSP profiler
  features, debugged Hatari DSP emulation issues.

  including I/O memory access & TT emulation (timer-C, video).  Ran
  some test programs on real hardware and wrote some test programs
  himself.

- Jorge Cwik (Ijor): creator of Pasti STX disk image. Reverse-engineered
  some decapped STF chips (GLUE, MMU, Shifter) and many low level description
  of the STF inner work, very useful to improve emulation accuracy.

- Paulo Simoes (ljkb): made some of the first descriptions of wakestates,
  as well as documenting all positions where hi/lo and 50/60 switches
  can create specific lines' length.

- Troed Sangberg (Troed of Sync): accurate description of the GLUE state
  machine for STF/STE in all wakestates (display signal, sync signal, ...)
  and the resulting lines' length used in overscan / hardscroll. Coder
  of the '{Closure}' demo which makes huge use of these techniques.

- Christian Zietz: recovered many original ASIC schemas for Atari's chips
  and helped in reverse-engineering the behaviour of those chips.


 Code from other projects
 ------------------------

As a true open source project, Hatari also uses some code from other
projects which we would like to acknowledge here:

- Hatari binary releases include latest version of EmuTOS:
  http://emutos.sourceforge.net/

- Most of the original ST hardware emulation comes from the WinSTon
  source code which has been written by Paul Bates.
  (http://www.sourceforge.net/projects/winston/)

- The original CPU core has been taken from UAE which has been written
  by Bernd Schmidt and others. (http://uae.coresystems.de/)

- The new alternative CPU core has been taken from WinUAE which is
  maintained by Toni Wilen. Huge thanks to Toni for accepting ideas
  and patches not specific to Amiga emulation, as well as keeping on
  improving the accuracy of 68000/20/30 CPU. (http://www.winuae.net/)

- Some parts have been taken from the emulator STonX that has been
  written by Marinos Yannikos and Martin Griffiths.
  (http://stonx.sourceforge.net/)

- A lot of code (e.g. the scancode keyboard mapping, Videl, NVRAM and
  DSP emulation) has been adapted from the sources of the emulator
  Aranym. (http://aranym.atari.org/)

- The code for decompressing ZIP files (unzip.c) has been taken from
  Gilles Vollant's miniunzip program.
  (http://www.winimage.com/zLibDll/unzip.html)

- The routines for saving and loading the ASCII configuration file
  (cfgopts.c) have originally been written by Jeffry J. Brickley.

- The new sound core uses (or used) some code/ideas from the following GPL
  projects :
  * 5 bits volume table and 16*16*16 combinations of all volume are
    from Sc68 by Benjamin Gerard.
  * 4 bits to 5 bits volume interpolation from 16*16*16 to 32*32*32
    are from YM blep synthesis by Antti Lankila.
  * Since Hatari 1.7, volume table based on measures by Paulo Simoes

- The IDE hard disk emulation is based on code from QEMU.
  (http://www.qemu.org/)

- The MMU emulation for the 68030 has been taken from the NeXT emulator
  Previous (thanks to Andreas Grabher!). Since Hatari 1.9, this is now
  taken from WinUAE which uses the same code base.
