The Atari ST was a 16 bit home computer that was very popular in the late 80's and early 90's.
It was the direct competitor of the Commodore Amiga and both machines were based upon the 68000 cpu.
It was first released in 1985 and was very sucessful in the professional music industry due to having MIDI ports as standard.
EstyJS aims to emulate the ST accurately enough to be able to play many of the classic games made for this machine.
The sourcecode for this emulator is available in my github
Work in progress
Currently there are some things not emulated:
- writing to floppies
- Partial keyboard/mouse/joystick
- timer pulse width & high accuracy < 1 scanline
- border effects
Joystick 1 is emulated using cursor keys and ctrl (or a real usb joypad).
