Not in the way you're thinking of (except DS-mode DSi and 3DS flashcards, which have a full copy of an exploitable DS game in internal memory); flashcards have their own processor that loads a file from microSD and simulates more (Sky - even the red version was never patched, they had to invent new commands that obviously weren't emulated) or less accurately an original card!Adding onto this, flashcarts are like custom carts, right? Like they have their own EPROM or EEPROM?
