What is dynarec compiler in option ?
If I disable it,all demo and games are not work.

Disabling it causes the emulator to run in interpreter mode, very slow, you should never need to disable that option.
dynarec is the recompiler converts psp instructions to pc instructions on the fly, usually very efficiently it might recognize a sequence of instructions and rewrite them more efficiently for the pc to understand ..etc
Where interpreter has no shortcuts it's probably more accurate but will be slow.
You can take a look at compiler.xml to get a better idea what dynarec does.

The probrem is not work.Not "very slow"

what? you should use google translate instead. probably it will be more readable.

And don't work for the same reason hyakki told you.

PSP and PC are similar cause both have similar pieces to work; however those pieces are not the same on a PC and PSP and for that reason the orders that the PSP needs to work have to be "translated" on the PC so it know what to do.

That's true. Since the syscall instruction has been implemented with a new Java reflection mechanism, the interpreter is no longer working.
As the interpreter support has been discontinued for several years now, the option to disable the compiler should be removed. The compiler should always be enabled.
