@ItsFelix - You are best off using the file in the ZIP, which includes all the necessary data needed to unlock the memories. I tried using a completed version of White and ticking all the memory flag boxes in the program as usual, but it didn't work until I used the one he included in the ZIP (see screenshot of it).
So, no need to import your save data for Black. Thanks to @suloku for this fine work!! I was desperately searching for my DSi and was going to mod it to get a ROM of White.... and do the memory thing via DS Wireless Communications. But I am glad I don't have to.
