anyone ever use one before?
do they work good?
and how is the GBA rom support?

and how exactly do they work do i just connect the cart to the pc and it sees it as a usb drive?

Be careful they only work with consoles that have old firmware.

I am still trying to get my head round what is needed to run backed up original games.
