I've just installed a neo 2.2, I have tested it and it works fine.
Know I'm trying to boot a dvdr. I previously used to do the knife swap.

I have regionx, A burnt iso of ar2, dmc (original).

I know i can play dvdrs but know that i have installed the chip i was wondering how I could go about swapping from regionx to ar2 to dmc to dvdr using the chip? instead of knife method. please help.

psx b/ups work a treat and ps2 cdr backups are easy. ;)

yes you can boot dvdr with a dvd region x and dmc demo. i got my boot method form this site
