Some DS games, you can unlock special features if you insert a specific game into the GBA slot of your DS. In MegaMan ZX for example, you could fight previous MegaMan Zero bosses, if you inserted the respective MMZ game into slot 2.
The question is: Is this possible with the EZ Flash IV ? I tried to install the Rom into the cards NOR space, so its present on the flash cartridge itself instead of the mini SD card but it wasnt recognized.
Does anybody know of some programs / tinkered firmwares for this card to enable such a feature or knows of any other flash card that can do it ?
Its pretty hard to get your hands on some old GBA games and the batterys are already starting to die (at least some of mine are already dead) and a flash card is really the most relient way of playing these games in a long run.
