Just so you know, if you're buying flashcarts online, some shops can be dodgy, so signing up to paypal means you aren't directly giving the site your card details. It's honestly much safer than directly giving the shop your details. I don't see why you don't want to.
I did end up getting the acekard 2i, is this where I'm supposed to get my firmware? http://forum.romulation.net/index.php?topic=42121.0 Do I need the loader too? I don't remember seeing anything about a loader. And where would the loader go?
http://linfoxdomain.com/nintendo/ds/ Scroll down till you see a firmware loader called AKAIO. Best one for the Acekard 2i I just got mine. And I love it.
