Please answer to the best of your ability. 1. What exactly (code, feature, etc.) is preventing us from loading custom firmware or commercial roms onto a SD card and to the DSi? 2. What code inside DSi taken pictures enables the DSi to recognize/display the photo and vice-versa? 3. *noob question* Is it possible to save file(s) as a binary file and a .cue file? If so, how? 4. Has any exploit been found in any game/app and if not where do you think it will be most likely to find an exploit? Thanks.
