Is there a tool to edit the type chart and to add the fairy type?

While I have done no editing of b&w2, my experiences with Platinum and HG/SS say it can't be done.

I could be wrong, but it's pretty improbable I would thinks.

1. you must know how to assembly, is not easy and is have a lot to do. so don't ask a instant result. like bond said is have a lot to do, like re-arrange system to make them seems correctly. is not like pure hex editing, you need IDA pro.

2. is need long time to finding code for controlling type on pokemon games, for weakness table is was found (search on the forum or pp wiki for another information).

since is need assembly on some part of overllay part (is not like map hacking since is just little manipulate the OVA -i can say is just replace old data only, not increase size of Data).

if i was found something on assembly i won't share it until i was fixing something =P

is NO TOOL to specific editing system, it will won't exist.

the best tools is IDA pro for assembly, hex editor for hexa editing, and debuging is desmume, no$gba and another debug tools. system part is different on data part, if you do doing small mistake on OVA, it will won't work correctly

is possible do that, but is not easy task.
