Hacking DSTWO update with another DSTWO?

[Fudge]

I have 2 DSTWO's. One is running the latest firmware, however on is on Fish Tycoon. Is there anyway I can update the other one through using the first one??

1, download latest EOS and dstwoupdate.dat file which from the latest fireware of DSTWO
2, Run dstwo_load_NDSL.nds

dstwo_load_NDSL.rar (21.91 KB) with working flashcart, then u should see this screen:

3, insert DSTWO you wish to update (without microsd card!!!)
4, insert the microsd card which stores latest EOS and dstwoupdate.dat file into DSTWO
5, Press B
