I would like to make it clear that besides GSC coming three years after RBY, and besides XD coming five years after Colloseum, there are no other confirmed timeline connections. Anyone who says otherwise is basing this off of assumptions and fallacies. The anime and manga are based off of the games, not the other way around. Any other timeline comparisons are only fanbased speculation.
I'm putting more work into the tournament when I can. However, I'm very busy nowadays, considering I'm back in school with very tough classes, as well as marching band. However, I'll get some more work done this week.
Except, D/P/Pt and HG/SS happening around the same time is generally confirmed with all the stuff, like Cynthia in HG/SS, and Jasmine in D/P/Pt, along with the Red Gyarados mentions in D/P/Pt. Granted, it's not 100%, but I expect that if Jasmine mysteriously disappears to Sinnoh, or says she's just returned or something, then it will be 100% confirmed.

Sure, R/S/E
still doesn't have a clear timeline place, thanks to no real hints, and the FR/LG and R/S/E thing is just a fan guess, but it would make sense as it doesn't require a Time Capsule or a Pal Park(Which is another way that D/P/Pt is similar to G/S/C's originals. It had a way to interact with the gen before it.) to trade between them... But that's speculation until more info.
And the only reason we brought up the manga is because it follows the actual release, unlike these games. So it was brought up to confirm the timeline
wasn't the same.

And we all know the anime doesn't hold any credit timeline wise, I mean I don't think Ash has had a birthday yet, so that should tell you something there. =P
/EDIT: I just got hax'ed by Argenta. Of course she had to toss out Glaceon against my Garchomp that doesn't have the Ice blocking berry. And of course it has to faint me in one hit while I only take off like a third of it's HP. >_>
