Okay so here's exactly what I did;
Opened Rng Reporter 9.96.5 Beta.
Click the "Ds Parameter Search" button.
Put in my R4 (Does RNG work with roms? Or am I out of luck?)
Started up Pokemon white 2.
While in the menu I waited until my computer clock (synced with Ds clock) said 18h 22m 00sec, then I proceed to click "continue" in my game.
I saved my character at the top of the stairs in the sewers. (No Npc is around or moving on screen, so I assumed this would work).
I use sweet scent.
I get into a battle with a level 15 zubat.
I throw a master ball and catch it.
As fast as possible I run to the nearest Pokemon center, and get onto the GTS, and use pokecheck to see it's Ivs.
I input the Ivs. (Can someone check if I imputed them correctly, in the guide the picture shows the min and max Iv tables are different, but mine were the same)
I then shut the power off, and noted the time was 18h 28m 05sec.
After I put in the rest of the info (As seen in picture above) I proceeded to hit the "Search" button, but did not get a seed.
I am using this guide:

Thanks again!
