This platform rivalry was often reflected by the owners and was most prominent in the Demo Scene. The ST was primarily a competitor to the Apple Macintosh and the Commodore Amiga systems. It was also the first home computer with integral MIDI support.

It had an innovative single-chip graphics subsystem (designed by Shiraz Shivji) which shared the full amount of system memory, in alternating clock cycles, with the processor, similar to the earlier BBC Micro and the Unified Memory systems that have become common today. The Atari ST was the first computer with a fully bit-mapped color GUI. Although the Macintosh was the first widely available computer with a graphical user interface (GUI), it was limited to a monochromatic display on a smaller built-in monitor. It was similar to other contemporary machines which used the Motorola 68000, the Apple Macintosh and the Commodore Amiga. MaxYMiser FM v1.The Atari ST was a notable home computer, based on the Motorola 68000 CPU, with 512 KB of RAM or more, and 3½' floppy disks as storage. We Were HD version under GEMDOS HD (file handle access) See doc/release-notes.txt for the full changelog. Hatari now defaults to the SMALL_MEM build option, using less RAM during emulation Improved cycle accurate YM2149 emulation, supporting new effects (syncsquare in maxYMiser v1.53)īetter value for MFP GPIP bit 7 (STE DMA sound and Falcon sound)įor SCSI, improve 'Mode Sense' and 'Report Luns'įor IKDB, better emulation of commands $A and $Bīetter MIDI using PortMidi (Linux/Windows/macOS) Improved VBLANK position in 50 and 60 Hz mode More accurate MFP emulation, combined with the new internal timers Various CPU improvements (FPU, IPL timing)įaster CPU emulation for 68000 in cycle exact mode (speed up emulation by ~7%)

Major rewrite of the internal delays/timers, speed up emulation by ~10% on average Hatari is open source software and is distributed under the terms of the GNU General Public License (GPL). Unlike many other Atari ST emulators which try to give you a good environment for running GEM applications, Hatari tries to emulate the hardware of a ST as close as possible so that it is able to run most of the old ST games and demos. Using the Motorola 68000 CPU, it was a very popular computer having quite a lot of CPU power at that time. The Atari ST was a 16/32 bit computer system which was first released by Atari in 1985. Hatari is an Atari ST/STE/TT/Falcon emulator for GNU/Linux, BSD, BeOS, Mac OS X and other systems that are supported by the SDL library.
