IV abuse in the High Link
-------------------------
This is something I figured out last night and the results were rather nice:
Jolteon #135
Nature: any
Ability:
Quick Feet - High Link poke!
Catch location: High Link
31/31/31/31/31/31
Doing this is very similar to hitting one's CGear seed. The way it works is that right before you show up in the High Link,(the frame when the screen changes from black to you in the HL) the MTRNG reseeds. That reseed can be treated exactly as starting up the CGear in terms of hitting it your seed.
This is what I did:
-Find a CGear seed I wanted to hit. I used 7E2345BB, delay 4442, frame 30
-Click on the orange part of the CGear and choose "High Link"
-When it says "xxx warped to the High Link", pause the emulator
-Slowly advance frames counting the number of frames and watching for the MTRNG to reseed so you know what you're aiming to hit.
-The point 1 frame before reseed is where you need to get back to.
-You need to hit the right second AND the right delay ON that reseed point.
-Hitting your seed once normally with the CGear and writing down the encrypted seed is a good idea, as you will see the same resultant seed on hitting it when entering the High Link.
Once in the High Link:
Generally, when catching pokemon and abusing the MTRNG frames, you want to be on the first frame you want use for an IV. In other words, since my frame is 30, I want to be on frame 30 when I get into a fight. The High Link is different. You must get into the "battle" with your desired poke 0x15 IV frames early. If my target frame was 0x1E in the overworld, it would be frame 0x09 in the High Link.
The way I did it was to use an emulator and hit my delay first, leaving it 1 or 2 back 1 fame before reseed. I paused the emulator here and adjusted the Windows clock to 5 seconds before the desired second. Once the second hit I unpaused the emulator and the delay and time advanced just right to cause the CGear to reseed in my favor and hit my desired seed within the High Link.
I suppose that with practice this might be do-able on a normal cart. ZOMGTimer would probably be a huge help.
Anyway, there you go, IV abuse in the High Link. Now we can have great DW pokes in different pokeballs, not just bred in plain pokeballs. Also, competitive Speed Boost Blaziken is now possible among other things.(since they're all male)
For the PID/nature, PIDRNG can predict PID and nature might require a few state reloads.
