Can someone explain MMD's FAT problem to me?

[RyanGannon]

Ok, I have DSOrganize and NDSMail. Both of which have problems running because of FAT. Now I thought that FAT was a disk format and my CF is FAT, so what is it that is causing the problems?

[RyanGannon]

OK so far I've found this

and I know it's in some way relevant to me but I have no idea what to do with it.

I think it is the structure of the MMD, all the MMD is is a modified GBAMP, which makes it not to compatible with homebrew, not sure on that though

[RyanGannon]

There must be some way of hacking MMD or cracking DSOrgaizer to make it work though?

if the mmp/d is just a modified version of the gbamp, couldn't we just use the gbamp hack on the mmp/d, and run programs off of moonshell and stuff?
