OS's first US airdate was September 8th, 1998 so you got that right. AG's first airing in the US was March 15th, 2003 so the US Hoenn Cap's ID No should be something like 031503.
Isn't the Sinnoh hat still being distributed?Seeing as how I missed ln getting the DP Hat, I’m going to get Alola. I have been watching the Sun & Moon anime and I have been really enjoying it. But my first choice would have been DP simce it’s my favorite series from the anime yet.
