Hello everybody!
I had wonder with my computer is my current processer is x86 or x64 ?
My current processer is Intel Pentium Dual-core E2140 @ 1,600 MHz
And my current operating system is :
Microsoft Windows XP x86 Professional Edition Service Pack 2
I said because I want to play HARVEST MOON - MAGICAL MELODY.
And I had one more question to tell you is:
What is the JIT and why the JIT make my computer error(s) when I start emulate in Dolphin-emu
Well in today I dicovered one website.
I see he or she can play HARVEST MOON - MAGICAL MELODY as well on Dolphin-emu SVN R945. Let's see !!
But I can't read any word in that website .
I can only guess, what is he or she telling .
After that I use Google Translate to understanding.
I had translated only one message.Let's again
Please tell me ,what should I do.
And the last, Thank you very much for you ask me.

any duo core above processors support both x86 and x64 capability but you need the os x86 and x64 to run the correct binaries.

Hello lannyboy!
Oh!! It's really !?!
My computer has more abilities then my thought.
It's meaning, I can install Microsoft Windows XP x86 and x64 Edition.
So!, I've got two question to tell you are:
Can I use x86 program(s) on Microsoft Windows XP x64 Edition ?
And, What is the JIT ?
And the last,Thank yuo very much for your help again lannyboy .

[lannyboy]

64bits os can run both x86 and x64 binaries but 32bits only run x86.
JIT is a technique that helps to improve runtime performance of a program. that means dolphin program will run faster with JIT compilation.

Hello lannyboy!
Oh!! It's really !?!
Because I've got x86 programs for 98 % in my computer.
But with x64 programs, I've got only 2 %.
And I have to waiting for accept from my parents and sister before.
When I had accepted as well ,I'll can install Microsoft Windows XP x64 Edition.
Because me, my parents and my sister use the same my computer,
I'm meaning, one computer use all people.
Well! In the before I said "What is the JIT ?".
Because when I turn it on , Dolphin-Emu is going to error for all time.(Dolphin-Emu on Microsoft Windows XP x86 Edition)
So! and when I turn it off ,It's can run in the low of framerate (around 0.80 - 2.00 FPS).
And the last, Thank you very much again for give computer knowledge to me lannyboy.

When Jit is off the graphics can be more accurate but it is WAYYYYY slower. When It's on there are more glitches but it plays faster.
