ROM Hack Pokemon RNG Manipulation help

[UnwantedFortune]

I've spent all morning trying to get the 3DS RNG tool to work with my 3DS and Omega Ruby, finally with luck. The only thing now is, I have no idea how you calculate the frames you're supposed to stop on. (Pressing Calculate in the 3DSRNGtool doesn't actually do anything, and inputting information changes absolutely nothing from what I can tell.) Have I done something wrong? I don't understand where to even be looking. In case this is useful info, my TSV is 1124, and I'm on a n2ds. I've connected my 2ds to the tool, but as I said before, nothing seems to change regardless of what I do.

EDIT: I followed this thread to set everything up, but unless I'm just completely missing it, it doesn't explain at all what to look for or how to calculate frames.
