There was only one change, to fix a major bug in EmuDesk: if a desktop shortcut for a file/folder was dragged to the trash or a disk icon or an open window, then all the folders at the same level as the selected file/folder were included in the operation, causing unwanted deletes/moves/copies.

EmuTOS version 0.8 released

We are happy to announce a new public release of EmuTOS:

EmuTOS 0.8 --- May 30th, 2005


EmuTOS is a single-user single-tasking operating system for the 32 bit Atari
computers and emulators. It can be used as a replacement for the TOS images
typically needed today for using emulators and it is also running on some
real hardware, like the Atari Mega STE. All the source code is open and
free, licensed under the GNU General Public License (GPL).... read more

Second Beta Release of EmuTOS

Dear Atari Community!

We are happy to announce the second beta release of EmuTOS.


EmuTOS is a singleuser singletasking operating system for the 32 bit Atari
computer emulators. It is thought as a replacement for the TOS-images you
usually need today for using emulators and it is also running on some real
hardware, like the Atari Mega STE. All is open and maybe it is also running
on totally new machines in the future.... read more

EmuTOS has harddisk support


I'm proud to present you the EmuTOS harddisk support. See, what Petr the developer said about this:

I just commited a much cleaned up code that does the bus scanning. It scans for all available drives on ACSI, SCSI and also IDE interfaces. If
a drive is found it is scanned for partitions and all partitions are added. GEM and BGM partitions are also added to the drvbits.

I also added two XHDI functions that I needed for disk scanning. More XHDI fns will follow soon and at one moment I'll add the XHDI cookie and
MiNT filesystem drivers can start working...... read more

EmuTOS Release 011023 out

You can now download the first public release of EmuTOS. It is still very alpha. But it may be enough for some testing with STonX.

Posted by Martin Döring 2001-10-23

New video driver

There is a new fast asm coded bconout function. It supports most of the things we missed, like cursor, invers video, different modes... It is nearly the original atari's driver. And there are some bugs... ;-)

Posted by Martin Döring 2001-10-10

You want to help?

EmuTOS is a very young project. We try to create a free TOS compatible OS for to let it run on Atari ST emulators of all kinds. In the moment it is just tested on SToNX. We could need help at the following points:

- implement XBIOS calls
- implement screen handling better and in assembler
- one should not have to type "make clean ; make" each time one changes a file.
- would be nice, if .o files would be in archived libs for each subdir
- add argument specifications in function prototypes
- merge identical headers, and put them all in an include directory
- cleaning function prototypes, checking compiler warnings.
- complete vt52 console, in low, med, high rez.
- low-level floppy support (rwabs, booting a floppy)... read more
