He asked if you would pass him the rom or iso or Final Fantasy 7

That's what I was thinking (I made only German and English at school lol)
and so, my answer is

NOOOOOOOOO !!!!!

Remember the principles of emulation: you are supposed to own the original CD to rip it in .iso

please do explain cause im new to this kind of emulators so i dont know how to rip or even pass roms to a cellphone

Does anyone know if the XPERI keyboard works with Fpsece and which buttons work?

They are supposed to work...

Yes, the Xperia keyboard works and you can use all of the buttons. Just use the controller configuration or whatever it's called to set it up.
For maximum comfort and suitable usage, I have mine set as follows:
Up - W
Down - Z
Left - A
Right - S
Triangle - : / 8
Circle - ? / #
Cross - . / 0
Square - , / *
L1 - E
L2 - R
R1 - P
R2 - O
Start - Enter
Select - Space
Menu - Camera

Dude thank you very much you rock!!!!!

Hi, I have a lot of problems in my Xperia with version 09.5
When I enter the emu the grey down bar doesn´t show the menus (star, options, about, quit). But if i touch the bar where I know it is for example " start", then appears the text.
Then I can´t configure the keypad because when I slide the phone the joypad configuration prompt turns fatal (the colours and buttons go toghether, moves, and so on).
I am runing the Panzer General. First, the animated presention go slow, very slow. Then the sound turns really bad. It star to repeat all the sounds that make the game. Besides the game screen doesn´t fit to the phone screen. The game runs really slow.
What can i do to solve all this problems? Thanks.

Have you tried 0.9.6?

Hmm,
I had the same problems with the menu on 0.9.5 and 0.9.6 - I have upgraded (at different times) to both custom ROMs and the latest generic ROM (depending on your country) from here at xda-developers http://forum.xda-developers.com/showthread.php?t=475482.
Both seem to fix the problem with the menus, so I don't think it's an fpsece error.
If you don't feel comfortable with upgrading your ROM, I'll run you through the process. (Note that you don't have to though, as version 1.0 will support WVGA).
Good luck
