Hacking Help with R4i3DS

[Feateon]

So, I bought an R4 for y 3DS, and it works great; quite happy with it.
However, I have a game that simply will not work with it, and I'm wondering if its normal or just me or what not.
The game is Animal Crossing: Wild World.
I've downloaded the rom from several different sites, formatting anything to do with Animal Crossing before I put the new rom in.
I've also tried to do something call ARM7 to it, using a program I believe was just called ARM7.
It still refuses to work, and its a favorite game of mine. So is there anything I can do? or do all R4's refuse to play the rom?

It plays just fine on all the carts I have.
