I assume you are using 6.31 PRO which is essentially the same HEN as 6.35 Pro as I understand, certainly the same devs who created it. It depends on what you use it for though, I would check the net for compatibility for any homebrew, but the ISO loader seems pretty stable from what I have read. It is only the PSX support that interests me.
You can only play store bought PSX titles from different regions though, full PSN games need the activation changing.
I also believe there is already a downgrade path for 6.31 and 6.35 if you look around the net.
