Hacking GBA Mode buttons mapping ?

[DiNo29]

Hey
I just started playing Rockman Zero (3) on my DS with Supercard SD, having finished Megaman ZX Advent. But the buttons are horrible. Only A and B can be mapped (and L,R,start,.... of course), which is normal for a gba game, but A and B positions are horrible for a megaman. It should be B and Y.
So, is there any way to use the Y button in gba mode on the DS ? Map it so it act as A ? I really can't play megaman without it :/.
Thanks

Nope. But there was a special chip that did it before, but I think it was for the DS Phat only.
