3	* src/cpu/core_dyn_x86.cpp, src/cpu/cpu.cpp,
4	  src/cpu/core_dyn_x86/Makefile.am, src/cpu/core_dyn_x86/decoder.h,
5	  visualc_net/dosbox.vcproj: utilize host fpu directly (dynamic
6	  core)

The core means "Dynamic with no host fpu". On the other hand, "dynamic" directly utilizes fpu on cpu.
It is already in cvs codes. (wd added it)

but whats the point? wouldnt it just make it slower?.... like if it doesnt use the fpu wont it just make it work harder?

it's incase there is some bug in it.
That way you can play/test without that piece of code.
It are afterall development snapshots.

It shouldn't be visible to users, don't know why it's been made public.

ok, so...

a) makes it not utilize the FPU situated in your pc
b) has mostly negative side effects (mostly only good for debugging etc.)
c) shouldn't be used under normal circumstances....

correct?

correct.
although I wouldn't call it negative side effects.

whats the difference between full (simple and full (force) ?

You don't need it.

but... whats the difference?

I'll remove options next time or not commit it at all.

so the difference between the 2 is only for debuggers to know?

They don't need it.

ok then, since there is a choice between the 2 which is best for compatibility since both of them are visible in the current build? full (force)?

I am not responsible for what options are visible in what builds.

Clean cvs builds should be left at the default unless there's a
reason to change it (stability problems (unlikely) -> use the normal
core, game too slow and non-pmode (rare) -> set to the dynamic
core if on an x86 host).

(yes i deleted my last post here)

yes i just updated and yea the normal (simple) and normal (force) options are present in it..... wtf is the secrecy behind the differences between the 2 you still have failed to explain the differences.

I have to say that while I don't particularly care about the matter at hand, franpa does have a fair point: "You/they don't need it" is not an appropriate answer. I would hope that the "open" in OS would stretch to being open about what development is for if someone is curious enough to ask.

More to the point, though, making obfuscatory replies like that rather than being up front with people is far ruder and far more infuriating.

We are talking about CVS versions (not final), so I don't see any problem to what WD said. 😳

it doesnt matter if it stays in the final release or not... im just after knowing the difference between them.

i'm sure this question has been answered quite a few times on this forum.
the difference is how they are coded.
core normal is a case tree and and core that uses function pointers and splits up the operations in a load/operation/save part.
