With the reviews on gbatemp being out of date and all the constant firmware updates, even though I looked, I find it hard to determine what features this card actually has. With my current 512 mb cart I find myself out of space a lot, so I was thinking of getting the 2 gb version of this card since it's so cheap. Does it have... full rom compatibility? (recent arm fix problems? zelda ds?) dldi auto-update? full download play compatibility? fast menus? boot slot-2 carts like g6 lite? And two more specific questions: Does it save the savedata to cartridge after reboot or does it save it on the fly? Exactly how long does it take to write a 1 gbit rom to the cartridge? And lastly, comparing it to the r4, what's it missing feature wise? Thanks for the answers, guys.
