Doh! OK, the OS4 UBoot Configuration Menu shows 4 selections:
1) Default (JIT)
2) DebugJIT
3) NoJIT
4) Debug NoJit
So running in 1) default, Petunia is translating 68K code to PPC and
has no interaction with Euae in anyway? Is that approximately close?

Here's a shortened Description:
Short: patch for faster icons & color mapping, 1.13
Uploader: pkeunecke@xxxxxxxx (Peter Keunecke)
Author: pkeunecke@xxxxxxxx (Peter Keunecke)
Type: util/boot
Version: 1.13
Requires: 68020+ and Kickstart V39+
Architecture: m68k-amigaos >= 3.0.0
....>8....
Description:
===========
IconBeFast is a small patch for the OptainBestPenA() function.
It will speed up the drawing of 32 - 256 color New-/GlowIcons.
The idea to do this by improving OptainBestPenA() comes from
Bernd Roesch, the author of the AfA_OS project. Thanks Bernd!
This patch works independent from AfA_OS and runs standalone.
The loading of 256 color icons can be 4 times faster or more.
You need at least a Workbench with 32 colors to get a profit.
Since v1.10, IconBeFast has an improved color mapping now and
should give much better results when displaying dithered pics.
Both, v1.03 and v1.13 are working with a 128/256 kB distance
table in memory to avoid many time consuming calculations.
Usually, these versions are about 25% faster than v1.10, but
the speed depends very much on the type of CPU....>8......
I've noticed a speedup when opening Work: directory in 800x600x32
gfxuae screenmode. Didn't measure it, put it's enough to visually detect.
I tried it with AmiKit, however I didn't notice much change. The A1 doesn't
have the 'horsepower' to play with this kitty. I have a friend that tried it
with WinUAE 1.0 on a HP.computer. God, it flies when you have JIT and
a P4 cpu.
Regards, Dennis
