I have looked at quite a number of forums, but i cant seem to find any information on this. 1. Has there ever been any hacks to obtain all Dsi Ware and share them like roms? Or running them using flash carts? Some of them are no longer available and it would be nice to be able to download them. 2. Other than Guitar Hero DS, are there any retail carts that have GBA expansion and rely on them for gameplay? Another unique cartridge would be pokemon heartgold for its ability to communicate with the pokewalker using infrared.
