Hatari
 Hatari is an Atari ST
and STE emulator. The Atari ST was a 16/32 bit computer system which
was first released by Atari in 1985.
Hatari tries to emulate the hardware
of a ST as close as possible so that it is able to run most ST games
and demos. It supports more graphics modes than the ST and
does not require an original TOS image (as it supports EmuTOS).
Hatari is an adaption of the WinSTon source code to the SDL
library, using the portable UAE CPU core
instead of the original, non-portable assembler CPU core.
There is also very experimental hardware emulation of the
Atari Falcon, a personal computer released in 1992, and the TT.
Features include:
- 68000 - 68040 emulation via the UAE CPU core
- Support for all known TOS versions (including EmuTOS)
- ST RAM size variable (from 512kiB up to 14MiB are possible)
- Optional cartridge images for the ST ROM port
- Most of the ST specific hardware
- ST Shifter with ST-High, ST-Medium and ST-Low resolutions,
overscan effects for all borders in color resolutions
- 512 color ST palette
- Many raster effects
- Scaling of ST-low resolution by factor two
- Interleaved lines rendering of ST-medium and (scaled)
ST-low resolutions for the TV "monitor type"
- Blitter chip emulation (not very accurate)
- PSG YM2149 emulation (soundchip) including STFM samples
- Printer emulation on GEMDOS and Hardware level (print to
file)
- Experimental support for RS232
- Experimental MIDI output support (no MIDI input/through
support)
- Mega ST real time clock
- IKBD emulation (keyboard, mouse and joystick) with custom
keyboard mapping
- Joystick emulation via cursor keys and joystick emulation
via a connected PC joystick
- FDC emulation using floppy disk images in standard formats
(*.ST, *.MSA and *.DIM)
- Support for packed disk images (PkZip and Gzip)
- Optional write-protection for disk images
- Partial ACSI emulation for harddisk support
- GEMDOS interface driver to mount a directory as a harddrive
- Support for memory snapshots (save whole system state)
- Driver for extended VDI resolutions
- Recording of sound as .WAV and .YM files
- Screenshots in .BMP format
- Animation capturing
- TOS versions 1.00, 1.02, 1.04 and 2.06 can be used in ST
mode.
STE hardware emulation
- Horizontal and vertical hardware fine scrolling
- Split screen techniques / in-screen video address
manipulations
- (STE specific) right border opening
- 4096 colors STE palette
- DMA sample sound ("microwire" audio balance support missing)
- STE joypads
- TOS versions 1.06, 1.62, 2.05 and 2.06 can be used in STE
mode
