There is no way

 

Rudolph did indeed make a tool in 3 flavours: one for slot-2 cartridges, one for the EZ-Flash 3-in-1, and one for use over a Wifi connection to a computer. Search the download section for "Rudolph's backup tool" and it should pull up all 3. There's a guide to using the 3-in-1 version here, I think the other 2 versions work in a very similar way, although I don't know anything about the Wifi version a quick search with the right words should pull that up.

Please excuse any incoherance, this post is brought to you from the wrong side of 2 glasses of wine on an empty stomach. Oops.
