Here is a modified version of the crack for use on the PROPER BAHAMUT release. Yes it includes the intro still:

I got XPA's release and it's working fine on my original R4.
I haven't tried playing online yet, what was that on the locked threads about not seeing each other?
And if I need to apply this patch, will I lose my save data?

I don't think anything will happen to your save data so long as you aren't modifying the .sav file.

same as Zombie
even I have both of them XPA and Bahamut, both work on my old R4 SDHC and EDGE too.
although i'm not yet trying the online mode, this game should be just worked fine.

PS: XPA seems to be rivaling with Bahamut now

This worked fine for me. M3 DS Real

it works just fine either online as SP..... it's the bahamut version....

I have a question about BAHAMUT's crack release. Does it change the game ID like Xenophobia's did? If so, what's the new ID?

i dont see anyone online do i need peoples friend code and how do i find out what mine is anyone

I've tried the xpa patch with the xpa release, and the modded patch with the bahamut release and both yielded the same results;
no white screen freeze, however 30 minutes - an hour into the game it freezes, and after that it'll always freeze at the xpa load screen until i delete the save file
