Neo 2.2 + UK PAL PS2 and original imports.

[mort]

I have a UK PAL PS2 bought Nov 2000 with a Neo 2.2 chip fitted.
Is there anyway that I can Boot an original import ( Final Fantasy X ) from
the states with the above.

If so exactly how please.
If not , then , if it is a chip problem which do I need exactly.

Also can anyone point me in the right direction as to UK suppliers and fitters of the latest chips , preferable the ones that also operate a collect and redelivery service.

Any help would be greatly appreciated

Thanks Mort
