They still have a GBA around and a DS Lite.  Will the CycloDS work with 
a GBA?

I am just not that familiar with the hardware on the DS.  Are you saying 
that
you can run the GBA BSP on a DS and that you have done this with the 
CycloDS?

I am trying to figure out the least amount of stuff to buy.  This is 
just a demo
system for me.

I am so confused.  Now I think I understand the DS hardware a bit but
the role of the CycloDS products and which I need is confusing.

I assume since the just use microSD cards with a FAT filesystem, you
can do everything you need to with them under Linux?
