final fantasy 10, neo 2.2, dvd region x???

I rather think you ideally need the Origachip rather than Neo2.2 to play import originals such as FF X.

Your only hope for using NEO2.2 is to have the DVD copied on a Pioneer A03 using Veritas PrimoDVD software. You'll have to find someone who can do this. The use the DVD Boot method (involving a DVD with a larger TOC than FF X) posted in Sgt-Dan and other places. Whilst you're on the AO3, find out what size the TOC is in FF X.

Let us know how you get on.
