Booting backups with Region-X (the new version without a dongle)

[horna]

Hello

I did some searching but didn't really come up with anything of use, so.. Am i able to boot backups with neo2.x and region-x (a new version, the one without that memorycard/dongle-thingy) or do i need that older version? Is there anything special that i need to know before getting that chip? my machine's model is scph-30004.
Thanks in advance
