Which RNG Reporter version are you using? In the newest version, it tells you the initial and target frame for the seed. Here's a snapshot I took a while ago while I was helping someone else:Is that ordinarily how a person finds the initial frame?
Ignore the red stuff. In this picture, I searched for seeds then I was looking for a seed I wanted to use. As you can see, it tells me the initial and target frames. For example, one of them starts on frame 28 and the target is 31. That's 3 ID seed advancements. So to get the ID/SID you want, just set the time / date that PBox tells you and hit the seed like a normal seed. Then say no to Juniper 3 times. If your timer0 wasn't trolling, you should have got your ID/SID.
But if you're using an older version of RNG Reporter, you'll have to do it the old way (Which is perfectly possible, that's how I did it). The old version only gives you the target frame. So, to find your initial frame, you have to hit your seed, but don't advance the ID frame at all. Once you get into the game, go to the Seed finder part and put in all the info then hit the correct button. If it shows you that you hit your seed, then look at the frame you got. That's your initial frame. So then you have to hit your seed again, and this time do the correct advancements.
