Hello, resident idiot here. As the topic would indicate, I use a DS, and I emulate. I use an Acekard for slot-1, and an EZ 3-in-1 for slot-2. People usually say that to throw codes onto your GBA roms, to use a computer based trainer to add the codes to the ROM then throw it back on the card. This is kind of a pain imho, and I don't see why there can't be a homebrew that does the same thing while sitting on your card. IE, you'd not have to take your card out of the system, plug it into the comp, adjust the rom, reload it to the card, and throw the card back in the system. Instead, you'd modify the rom directly from your card prior to having the slot-2 engine take over while loading the game and cutting out the rest of the processes. In a different discussion, someone indicated that they had heard of such a program, but didn't know the name of it. So, does one exist? Or am I just daydreaming?
