Gaming Acekard and phantasy star zero help

[Bray4168]

My friend and I are trying to play phantasy star zero for ds. I have the r4 and he has the acekard. I can play online easily but it never works for my friend and we can't play with each other.

I remember this one. You both need the Xenophobia cracked version. It was the only version that allowed connecting with both retail users and pirated versions.
All other versions, like Bahamut, could only connect to other people with the same Bahamut release and would not work with retail nor Xenophobia players.
