Disable Evolution? Prevent releasing?

[Sapph the Knight]

So, this is probably something that is explained on the wiki or in a thread elsewhere, but I can't find it...

For plot-related purposes (such as, say, remaking yellow version), how do you make a particular pokemon unable to evolve, possibly until a certain point (pikachu, for example)?
Adding onto that, how do you disable the ability to release a particular pokemon?

In def pbCheckEvolutionEx(pokemon) add:

return -1 if isConst?(pokemon.species,PBSpecies,:PIKACHU) && $game_switches[XXX]==false

under:

return -1 if pokemon.species<=0 || pokemon.isEgg?

with your particular switch that determines if it's time or not for pikachu to evolve, aka when the switch xxx is true/on pikachu will be able to evolve.

as for your second question it's been asked many times, this is what I found with a 2 seconds forum search, I'm sure there's more:

Remove the evolution lines from your pbs files
Add them back upon full release

Can't tell if joking or confused, haha.

Thanks! I suppose I just suck at finding things. >>;

That only works if there's no intention to have the pokemon in question evolve.
