Will I'm sorry but you can't do any useful comparison on the emaulator.
The time management is completely broken on the emaulator. For example on my
K6-2 450, Tiger thinks that the time passes 10 times faster. So it moves 10
times faster than it should.
I do not think it affect Genius in an equivalent way, so one program might uses
10 times as much CPU time as the other one, and the result is going to be
totally misleading (it could even be that Tiger gets an advantage because of
this, actually I don't know).
I think I'm going to have to repeat this a zillion times from now on: you cannot
compare the strength of chess programs (and Tiger in particular) on the Palm
Emulator (POSE).
Don't use the emaulator to make strength comparisons. Please use a real Palm.
