Dragon is weak to itself in Generation 1, but it's never used since the only move is a flat 40.
It's possible to deal 0 damage in Generation V due to the way it handles screens.
X Accuracy makes you ignore accuracy check in first two gens. Pretty sure this works with OHKO moves.
The 1/256 oddity is still present in Generation 2, but in a different move (100% status like Dynamic Punch is actually 255/256)
Struggle uses type chart in G1, meaning there is absolutely no way to solo game with Caterpie and Metapod (as AI doesn't actually track its PP, and there are some Ghost trainers you can't avoid). Even Magikarp theoretically can, thanks to event moves.
Elixir and Max Elixir were misspelled as Elixer and Max Elixer in Generation 2. No idea why.
