Hey man, I see no one got back to you on this yet...
I copied Fifa today, no problems loading it up. But I dont have a neo chip, I have a regular 8 wire modchip. Yet, even with the 8 wire chip I have to do my boot the long way for FIFA.. heres what worked for me, give it a try.
Put in gameshark cd, power down. Power up, and keep HOLDING IN the power button.
Start game with/without codes. When it says to insert the cd, let go of the power button, and the tray will eject.
Quickly swap the GS cd with your copy and let tray close on its own. Instead of pressing "X" to boot, press "L1, L2, O" ALL TOGETHER AT ONCE, and hold until screen goes black.
After that it boots for me.
Hope this helps. Good luck, its a sweet game.
