Hacks For GBA e-Reader on DSlite?

Anyone know any hacks for the GBA e-Reader for DS? Like how to fool it into playing those games without the silly cards?

Well you need the cards to use them. Do you to want to use it for the DS?

I've got a DSlite and it works... Or atleast boots the game (Which was Donkey Kong Jr.) saved on it.

If you had a phat, it most likely wouldn't fit, which is why I asked.

So I can't exploit it in any way to use it as memory or something? I had this weird dream that I could use it as a Slot-2 device to boot GBA roms... or was it that DSlite Browser Memory Expansion thing, I can't remember. Sadly it's a dream that will never happen...
