So how can I guys tell if it's compatible? The thing is I had a DSi a while ago, then I sold it. Now I purchased again DSi on ebay and I have my AK2i card at home. I opened and checked it. It's original. It is AK2i Yellow PCB - HWID 81and uses a sst chip. Any help guys? ![smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
