hatari 2.4.1+dfsg-2 (arm64 binary) in ubuntu lunar

 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 most other open source Atari ST emulators which try to provide 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 Atari
 games and demos. Because of this, it may be somewhat slower than less accurate
 emulators.
