Playing GBA Roms on ds

I have been using an ez flash 3 in 1 to play gba gameson my NDS.
But now my ez is dead and won't save and it just all came apart when trying to change the battery. Anyone know what other slot 2 cards you get get to gba games on. I'm using m3 simply and m3real.

And also where do i get one from.
I don't understand why no one has been able to emulate the gba on a ds without one of these crappy things.

It's not emulating, it's really just sending the data to the gba slot.I'd...think you would just have to buy another of it, unless you buy a far older flash cart, the old gba ones...

ok. I have found somewhere selling them. How reliable are ez v's?
If i buy another is there a good chance it will be crap again?

Everything has a life span.THat said, I have no idea how long they might last, all I know is mine is still going.ezflash V mine is, still going but hardly used so no idea of life span.
