I'm an electronics engineer by trade. My theory tells me that it should be possible since slot-2 used a noPass to boot NDS code. Maybe it can be done in reverse. The slot-1 copies the GBA file to the Browsers RAM and boots from there. I know nothing about DS architecture or the amount of software coding that would be needed to do something like this. For those out there that know DS hardware/software code could something like this be possible?
