Problem with AR code for Sword of Mana

[OLungfish]

The code is the Area Mod which I have ported from Codebreaker to AR.
The code is 022003B4 0000????, which I have confirmed working in VBA, the value I used is 062b, which is the final save spot.

I'm slightly confused here. What is the actual problem?

The code doesn't function on an actual AR

Oh. I think there may be some screwy thing with it needing to be encrypted, and have a master code, or something to that general effect. I really don't know a lot about it, other than I've managed to fail to create GBA AR codes that work on a real AR.
