Frequently asked questions:
Q: I can't compile Hatari!?
A: You should check if you have installed all the tools needed for
compiling Hatari: The GNU C compiler (GCC), CMake (see
files for the SDL library and the ZLib compression library. Download
page lists few optional libraries which presence allows Hatari to be
built with some extra features.
Q: Why is Hatari so slow? Are there any possibilities
to speed it up?
A: Have a look at the
of the manual.
Q: Game XY does not work, what can I do?
A: There can be many reasons why a game does not work immediately. Changing one
of the following configuration settings often helps:
Many ST games often need a certain TOS version to run right. Old games
often only work with TOS 1.00 or TOS 1.02, so you should try these TOS versions
first. If the game still does not work, you should also try TOS 1.04 and 2.06.
Some games also either need a NTSC (US American) or a PAL (European) TOS,
so it might be useful to test these different types, too.
There are also some games which do not work in STE mode - but there
are also some few games which only work in STE mode and not in ST mode.
So changing the machine type might be worth a try, too.
Some games also need certain RAM sizes, for example some games do not work
with 4 MB memory size!
And finally, try to enable the "Slower but more compatible CPU" and/or
disable the "Patch Timer-D" in the system options dialog. This slightly
increases compatibility with the real ST. In some few cases you also have to enable
the "Slow floppy access" option in the floppy options dialog to mimic
the speed of the original floppy disk drive.
Q: How can I use MIDI on Mac OS X or Windows?
A: On MacOS and Windows, MIDI support requires building Hatari with
PortMidi library. Whatever that supports, should work also with
On Linux, if Hatari is built without PortMidi library, it uses raw
access to the MIDI devices. This allows using MIDI ports also for
other things than MIDI events, such as debugging and network
Q: Why is the 68k CPU speed limited to so few MHz?
A: The development goal of Hatari is to provide a good emulator for running
old games and demos, so we focus on a cycle accurate emulator.
If you rather want to run GEM applications as fast as possible, you should
better use another emulator that better suits this goal.
