I am having a difficult time finding any official spec sheet on the GBA Expansion of the M3DS-R. I have a couple questions, some of which I asked in a review topic, but instead of hijacking that topic (and so others can find the same info) I figured I would ask in a separate topic. 1. Is the GBA Expansion memory volatile or NOR like the 3 in 1? 2. I have read that GBA support is buggy, but cannot find anything concrete except some complaints about real-time-save (which I dont care about). Is this the only GBA issue? 3. I understand that the GBA Expansion saves to a battery, and backs that save up on reboot. Is there a way to force that save to backup without rebooting? (I.E. a 'Save' button combination) 4. Does the GBA Expansion use raw '.sav' files that are compatible with VGBA or Supercard? (I.E. can I use my Supercard SD GBA saves on the M3DS-R GBA Expansion without conversion?) 5. Is GBA support fullspeed? My Supercard SD runs many games (Final Fantasy VI, FFTA, Megaman Zero, etc...) much slower then the actual cart would run them.
