Setup is:

1. Download/install LINQPad 7.
2. Download dev build PKHeX.
3. Press F4 in LINQPad and add PKHeX.Core.dll to first tab, and PKHeX.Core to second tab,
4. Change the language at the top to C# program, then copy/paste the script in verbatim.
5. Edit your params (thresholds, advances).
6. Click run. Unsafe frames will have a * by them.

Chain continuation is calculated at the end of a battle when pressing A to close the exp gain screen.
You'll generally have a delay between 20-100 with menu mashing.
IVs are generated by walking into the grass patch aka Wild RNG.
