  He also provided patches for Audio Sculpture's custom IKBD program
  and MacOS screenshot dir handling.

- Thorsten Otto: improvements to the code that patches the TOS ROMs,
  support for Pure-C long symbol names, a.out symbol table, MINT+ELF

 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:
  https://emutos.sourceforge.io/

- Most of the original ST hardware emulation came 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 current CPU & FPU cores have 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 and FPUs.
  (http://www.winuae.net/)

- Parts of the NCR 5380 SCSI emulation are based on code from WinUAE, too.

- 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, SCC
  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.
