EmuTOS

EmuTOS is a replacement for TOS (the operating system of the Atari ST and its successors), released as free software. It is mainly intended to be used with Atari emulators and clones, such as Hatari or FireBee. EmuTOS provides support for more modern hardware and avoids the use of the old, proprietary TOS as it is usually difficult to obtain.

Features and compatibility

Unlike the original TOS, the latest EmuTOS can work (sometimes with limited support) on all Atari hardware,EmuTOS documentation

Support lacks for some deprecated OS APIs, though all Line-A API functions are included. By design, EmuTOS lacks support for non-documented OS features. It has some support for Atari Falcon sound matrix, including DSP support since version 1.1, and while VDI supports 1-, 2-, 4- and 8-bit interleaved graphics modes, support for Atari Falcon (or Amiga) 16-bit resolutions is completely missing. Therefore, certain old games, demos and applications, and also some Falcon-specific software may not work.
