WHY WON'T MY PIKACHU EVOLVEEEEEEEEEEEEEE!!!!!?????
seriously, I had a level 80 Pikachu in Red and it didn't evolve! My brother got so frustrated when his reached level 90 he thought it had bugged and restarted teh game, only to 2 weeks later find out it has to be done with the stone. Oh the tears!!
I would be incredibly surprised if there wasn't some random NPC hidden somewhere that told you how to evolve Pikachu.
Anyway, sounds like you needed one of these.
Everyone I knew who played Red and Blue had a copy of this book. It was pretty much required.
Although, I'm fairly certain the whole point of the Pokemon anime was to teach kids how to play the games. They showed where certain Pokemon were found, how they evolved, what moves they could learn and the different type match ups. Of course they got a lot of that wrong so it wasn't always helpful.
