1) What are the current limitations of the software? 2) Version 4.5 or under is required. Does this include 4.5.0-10E? (as I understand the 10E is just region, but thought I'd double check). 3) Any games currently not running? Will this flashcard be good for the foreseeable future, or is there some way it could be 'blocked out' on future releases? and finally 4) As I understand I can only store one game per SD card. Just to clarify, this means if I want to play a different game, I need to replace the current game on my SD card - will this lose the save file? Or can I back it up/leave it on the SD card for when I place my other game back on it?
