what is akaio, im assuming that it's like a software...unsure though.
and whats this? you can actually play gba games if you have akaio running?
found it at akaio.net/forums (btw is this the legit site)

+ Fix GBA Auto saving.

AKAIO is the best firmware for the Acekard, you unrar it onto your flashcard like the official firmware, it has better compatibility. I think the GBA thing is only if you also have a slot 2 or whatever flashcart for gba games, like the EZ flash thing

AKAIO = Acekard All In OneIt is probably millions of times better than the official firmware for the Acekard. I have never had a problem with it and I still use it. As of late I can't find my AK2i, but I have a DSTwo now, so I dunno...Here's the latest download - http://www.akaio.net/forum/viewtopic.php?t=686&f=8&sid=8546942ccf08f8e5dfff7b8f086f78a3

It's a firmware, far better than the official acekard firmware, you should use it.

will try out thanks guys :)
