I couldn't find anywhere that had catalogued everything on these games, only places where people had asked for one or two things and gotten answers, one very incomplete list, and a list of NARC locations for B2W2 which mentioned when something was copied from BW1 and stated the location it could be found in BW1.
So naturally I searched through and catalogued every instance I could find of this and put them all in a spreadsheet for people.

I can't confirm if any of these are even correct aside from trdata and trpoke, as I'm not very experienced with this, but this could be a very useful starting point for someone else, and if any of you experts out there want to make a copy of this spreadsheet for yourselves, catalogue everything you know for certain, and make it a public resource, please feel free. Each thing I put into the spreadsheet has a link to the place where I found someone stating that it could be found at that address, these people (usually from 10 years ago) could be wrong, so it may need to be verified. Except for a few which were found in a discord server I discovered existed after putting a ton of these into the spreadsheet.
And before you ask, yes, I do really, really hate it when useful information that you would previously be able to find on the internet is now locked behind searching through the pinned messages in a discord chat that you didn't know existed.
