This adds Pikachu, Cat, and "Small Bird" menu icons. The cat has a custom animation done by myself.
The Jigglypuff in the Pokemon Centre now uses the new sprite, nice 'n' pretty. Officer Jenny is also in Cerulean. The Pokemon from Melanie's house in Yellow have been put in Mr. Fuji's House, given the purpose of the house in RB is different. I think it ends up fitting very nicely.
Chansey has been given its proper sprite in Fuschia. Yellow didn't actually do this, as Chansey doesn't have a walk cycle, causing the stuff that exists to go unused. I wanted it, though, so I had Chansey just not walk and turn around. Oh, and it's in all the Pokemon Centres now. Yeah, that's a...lot of changed files.
This adds the Dubious Disc Salesman to Cinnabar Pokemon Centre. I chose this area because it's late in the game and it seemed a bit iffy to constantly have to go with Pokemon Centres not in towns. Cinnabar has some connection to Silph, so it makes more sense than just balancing.
There are probably improvements that could be made (eg. a quote as you buy) but the salesman code is surprisingly brittle so I'd rather not break stuff for hours for something that already works perfectly fine.
