ntsc dvd on an chipped pal psx
 

does anyone know how to play an us dvd-game on an modchipped ps2? (neo2 and ar2)

for example onimusha...

Oops - if you've read my previous reply, forget it. Yopu've got a DVD and there is no copying method yet! So far as I know, NEO2 doesn't play import originals.

neo3 will though right?

I'm not sure neo3 will play import originals. Playstationmods.com doesn't say it will play import originals, only backups. I don't use neo2, I use modchip.com.
