This version of Kronos1.71b is much better.

It'll be done for you.

That's an UB version that you're using, thanks to Philipp Donzé.

MagicMacX uses "Rosetta", the PPC VM for OSX with Mac Intel CPU.

May I suggest you to use ARAnyM in fullscreen mode. That mean you will
have to edit Aranym_files/config, changing :
FullScreen = Yes
BootColorDepth = -1
VidelRefresh = 2
VidelMonitor = -1
The simple fact to use MacAranym in fullscreen mode dramatically
accelerate the VDI speed. You may also adapt :
Enabled = Yes
IntegerCoefs = Yes
FixedSize = Yes
Width = 800 <-
Height = 608 <-
to the full dimensions of your screen.
Then rerun Kronos1.71b, and you'll see the real speed of the VDI.

JITc is not the only factor that accelerates ARAnyM's speed. We
could also use a natfeat nfVDI, but that is not completely stable.

There's no JIT that's true. It's slower that it might be. But
did you compared the speed of ARAnyM with existing ATARI hardware ?

Please report us about the usage of MacAranym in fullscreen mode.

We're all very interested with your comments. You're welcome.
