I'm really new to speedrunning pokemon, but so far I've downloaded gambatte and pokemon blue and have been trying that.

But then I see on youtube people have little menus that show their trainer id and pokemon id's and stuff. Idk how you guys get that, but that would be helpful to me so I can know if I'm doing the manips right.

Most of that doesn’t apply to these games really. The TiD manips are simply enough as is. And for the people who have it on the layout, it’s manually entered in themselves most likely. ie; FR/LG you enter your TID and it tells you a list of possible stats for the starter based on the time you select them and they just have that shown. To my knowledge there isn’t anylike like that for R/B because we don’t need them.
