So the patch worked, but not exactly :/
I copied the .sav file I had for Black 2 from NDS/saves to roms/nds/titles/saves, per the instructions provided
However, in order to get the patch to work, I had to rename it from "Pokemon Black Version 2.sav" to "black2.sav"
I've managed to get as far as sending a Pokemon from Dream Radar to Black 2, however when I attempt to use the Unova Link option to bring it over, I get a message saying "there is no research data"
I tried removing the original .sav file from NDS/saves, but the system created a new save file when booting up Black 2
Just to be thorough I got to a proper save point in the new save file, but was still unable to retrieve my Dream Radar data
I also tried putting a copy of the renamed .sav file into the NDS/saves folder, but the same thing happened
