What is PaCifiST?

Screen shot

PaCifiST is an excellent ATARI ST emulator written by Frederic Gidouin. It emulates the ST very well (see the specifications list below for more details). It is being updated very frequently (sometimes weekly). Watch this space! The Official PaCifiST homepage will tell you more about PaCifiST itself. Many games games and programs are working with it (see my games page, and my programs page). Games can be downloaded from other sites, there are also a couple on this site (see my games page).

PaCifiST can be downloaded from this page (see below). It requires a TOS dump, so basically you need run the TOS dump program that comes with every version of PaCifiST, or download another TOS dumping program from my utilites page. Put either TOS dumping program on an ST disk and put it into your old ST and double-click on it, and as if by magic a file of your TOS appears on your page. You can also download TOSes from other pages. (see my links page). BUT: TOS is still copyrighted so if you didn't own TOS and you have downloaded a full TOS you must delete it within 24 hours. I recommend you use the TOS dumping programs as these provide a very legal way of getting TOS.
