DS Firecard firmware

I wasn't sure where to put this topic, but general says it's for "Anything and everything" so I figured 'why not?'Anyway, I'm wondering if anyone knows where I can get the latest DS Firecard firmware.It currently won't run Ninja Destiny or Crystal Chronicals.
(Dragon Sword works fine however).I'm hoping the newest firmware will fix this so please let me know about it.
I currently have xmenu 2.52.If anyone has newer firmware or has been able to play these games on a Firecard, help me out please.

http://linfoxdomain.com/nintendo/ds/ I think the firecard is also labeled Firelink.

Thanks.
I got Crystal Chronicles to start (but was it worth it?)
Ninja Destiny is still unplayable.

We're so changing the description of general...
