I dont know about which card you are talking about, but this is what I found:

http://www.r4ids.cn/r4i-download-e.html

It's from R4iDS.cn

I hope I helped!

EDIT: Under 'Upgrade Patch Area' and select the one with DSi v1.4.4.
You can choose two versions, R4i Gold 3DS or R4i Gold Non-3DS.
If your card works with 3DS (see box or card) then choose the 3DS version,
if it only supports DSi choose the Non-3DS one.
