Thanks for your answers guys, I was asking this about EC because I read somewhere (don't remember where...) that the EC is like the old PID (related to much things of the pokemon), would be great to have the true answer from Kaphotics if he knows what exactly does the EC apart from spinda.
Moreover, like I said I used PCHex++ where you can't do all the things you can do in PkHex, I can't reroll the EC/PID in here.
But, I installed Pkhex yesterday and it's better, but longer to edit coz I must switch computer for sd card. Just noticed few incorrect legality checks, like regenerator talent on Ho-oH PC Kyoto, which can't be possible to set if I'm right (but you can do it right now).
I only use PkHex to get events with perfect iv, so I discovered your thread theSLAYER where you can get all of them in wc6 files, pretty awesome with PkHex where you can directly drop them on the left window :grog:
You made my day :creep:
Edit : the real question I have now is : Do I need to generate EC before PID or PID before EC when all changes are done ? Or it doesn't matter :confused:
Edit2 : Ok, so I found this http://bulbapedia.bulbagarden.net/wiki/User:Chenzw/Encryption_constant
From what I understand here, the EC must be rerolled when IVs are edited, correct me if I'm wrong.
