Okay. Finally got another shiny Pokémon after taking forever on route 3. I kept hitting the wrong Timer0 or getting wandering NPC's, but after a while, I figured out the exact frame I should be advancing and when I got my second Chatot, things went by a lot faster.
Right now, I'm RNGing another Pokémon (I'm basically building a team from the getgo in White so that I can use it for breeding later) and I've had some problems.
You see, I hit the seed often enough (occasionally, I get the wrong Timer0, but eh), but it seems as if my Chatots stopped working lol.
I'm RNGing in the interior of Pinwheel Forest and I advance like 80+ frames. Initial frame is 46, target frame is 153 and the starting frame I actually hit most of them time ranges in the 60-64.
Just now, I figured I'd advance 80 frames and see what I hit. I should've been really close to my desired frame, but instead, I either get frame 61 (my encounter slot is 9, not something you come across often) or like frame 269. I literally have nothing in between those. I'm guessing I hit frame 61, but that makes no sense with me advancing with two Chatots at high speed. I could do the saving method, but saving 91ish times is no fun, especially with wandering NPCs...
