Ok i'm gonna try it thanks you for that answer
So with the Keysav2 on the first page => I try to put 2 save with empty box, and i cant break cause it says it need some pokemon on the box
On the unofficial keysav2 from your post
I try to put on the file 1 => empty box 1
file 2 => full box 1
file 3 => full box 2
file 1 => 26.bin
file 2 => 16.bin
file 3 => emptybox1
And it doesnt work, it show me only a few pokemon and they are not from the box 1
