I think that there aren't any moves editor for DS roms.
I've found a move editor for diamond and pearl, in which i've edited the HM moves to my liking, however, using nitro explorer to extract the .narc, i've now been unable to find the matching .narc in my HG.nds (i extracted wotbl.narc, which if i read correctly contains move data)
Anyone know which narc i need to replace with my extracted and edited .narc from pokemon diamond? Because the set-up of the .narcs in HG is massively different from those in D/P/P
EDIT:
Ok i found the solution for editing moves in HG/SS, it's the wotbl.narc (at what level do pokemon learn moves) and the waza_tbl.narc (the move data), in the HG/SS structure the waza_tbl is in a/0/1/1 and the wobtl is in a/0/3/3
Special thanks for Alpha, his older posts helped me find it :D
2nd EDIT:
Alright, despite finding all the correct .narc entries, the game now crashes whenever i enter battle....
This leads me to believe that i still don't know enough as to what i am doing when it comes to replacing .narc files, anyone willing to help me out here or point me towards a move editor that works on HG/SS so i don't have to fuss with the .narc files?
