hatari 1.5.0-1 (amd64 binary) in ubuntu precise

 Hatari is an emulator for the Atari ST line of computers.
 .
 The Atari ST was a 16/32 bit computer system which was first released by Atari
 in 1985. Using the Motorola 68000 CPU, it was a very popular computer having
 quite a lot of CPU power at that time.
 .
 Unlike many other Atari ST emulators which try to give you a good environment
 for running GEM applications, Hatari tries to emulate the hardware of a ST as
 close as possible so that it is able to run most of the old ST games and demos.
