EmuTOS is a replacement for TOS (the operating system of the Atari ST and its successors), released as free software. It's mainly intended to be used with Atari emulators and clones, such as Hatari or FireBee. With it, the use of the old, proprietary TOS versions can be avoided, as they are usually difficult to obtain.

Features and compatibility[edit]

Unlike original the TOS, latest EmuTOS can work (sometimes with limited support) on all Atari hardware,[1] even on some Amiga computers, and has support for features[2][3][4] not available before: ColdFire CPU, IDE, FAT partitions and emulators' "Native Features" support.[5]

Support lacks for some deprecated OS APIs, though most Line-A API functions are included.[4] By design differences on non-documented OS features may still exist. It has only some support for Atari Falcon sound matrix or DSP,[6] and VDI graphics support for 8-bit, not 16-bit resolutions. Therefore, certain old games, demos and applications, and also some Falcon specific software may not work.[7]


Release 0.9.1 brought support for Firebee evaluation boards, 256 colours display for VIDEL systems and XBIOS DMA sound functions. EmuCON2 with TAB completion, and renaming of folders was added. A full-featured desktop is also now included in the ROMs, amongst other changes.

Release 0.9.2 supports SD/MMC Cards, the external IDE connector and poweroff functions on the Firebee platform. CompactFlash can be used, IDE media handling, FAT partition and media change detection were enhanced. Fixes and improvements for EmuTOS-RAM booting, fVDI compatibility and general VDI speed, ACSI and XHDI support (see Atari TOS), are included, plus other changes.
