I have a GBA and a Max Media Dock, can i play GBA games on my GBA with it.

The slot one card for ds i have turned into a brick. i have an r4 and have no use for this, i have given my gba to my girlfreind and would like to get her some hacked games on it. can someone help me i have not ben able to find any gba bootable software for it. its just a compact flash card reader to gba slot with a five pin usb conecter on it.

I too wish to do this. Also can I use the R4DS with this in anyway to play GBA roms on my DS?
