Yeah, there are so many :P Well at least I was the first with an English Shiny Druddigon lol. Didn't abuse that much on 5th as you did, but I already abused 63 mons ^_^ Made a 'To Do' list for myself, and I need to capture/breed 30 more Pokémon :p
Once you figure it all out. It really is. The coolest part is I don't have to be at my computer any more for a timer!!! I like being able to RNG on the road, in a plane, going out to eat, where ever! As I'm no longer restricted to a timer for the delay! All I have to do is memorize what time to hit, what my shiny PID is, and what Pokemon will show up and done! :D! Once I'm done updating my thread with my other abuses, I'll update it with 5th gen and you can see what I've done! I've only done captures so far, probably going to give a go at breeding within the next week or so.
Music, I can see why now that you went crazy on your 5th gen RNG spree. It is fun. I'm getting a bunch now. Shinies too! :D! I found an HP Electric spread with a shiny synch-able PID frame of 128 :P Only have to advance 74 times in order to hit it. I've used this seed about 8 times in 25 mins xD!
When do you start holding the button, and when do you release?
Also, is there anything you do to your parameters when searching for seeds with a keypress combo? As I thought Kaphotics said that you might have to change them with how many keypresses you have set on.
