. this is way past my level of understanding, but ill post my idea here anyway so you can laugh at my foolishness. on DS Lite and DSi, the bios chip is stored on a removable "block", i assume 3DS is the same. is it possible to re-flash the bios with custom firmware, by connecting the module to a hardware flasher?, i realize that reverse engineering the 3DS bios software is probably too hard, but maybe its possible to build custom software from the ground up to communicate with the 3DS hardware. then maybe some group could mass produce custom bios modules, it wouldn't require any soldering, and easy for the user to revert back.
