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 (last 5 digits of TID matches).
6. Click run.

RNG state is locked in right as you click on Rotom PC.

This is simply meant to demonstrate the logic for others to implement in their own end-user tools. You can also use this if you want to give it a try first before those tools are updated. It is not meant to be a polished or complete tool in itself.
