Again with this?
I agree with everyone who said hacking perfect parents is stupid. Although I did this because I thought passing all my good pokés from my Pearl to the R4, clone all of them and trading them back would be too time-consuming... In the end, I just spent two hours.
But all the hacks I made had the same damn IVs, Nature, moves and gender the legit ones had in the Pearl (again, I just didn't thought trading them to clone would be so fast).
The only "hack" I kept was Too_Hungry's Koffing and a Misdreavus I got with someone here. But now, I'm using his... grandsons, and I don't believe anyone would still call the offsprings hacked by now, by any means...
Although I'm checking their IVs with Pokésav >_> But still, I hatch even the crappy Eggs (now, I have 210 Eggs to check). God, that's why I hate Hidden Power breeding.
