3rd Generation Download

[Zeena]

Awhile ago, I downloaded a thing that allows you to see characters in 3rd generation on heRO, from these forums. I searched for the thread, but failed to find it. I just need help with it, because I no longer have desire for it. Do I just delete the transpack and it'll be normal again? Or, will I have to delete multiple things? I have no idea how many things were downloaded from the pack, but until someone replies, I won't touch anything in my RO folder.

Please help and thanks in advance!
