You can find him if you trigger the Shaymin event, where he asks you to write down the name of a trained that inspired you to open Seabreak Path, which leads to Flower Paradise, where you catch Shaymin.
in Route 224
well, he should be at route 221 for Pokemon pearl and diamond
At the beginning of the game, Professor Oak is in Mr. Pokemon's house. Mr. Pokemon's house is north of Cherrygrove City. After that, Professor Oak is in Pallet Town in his Pokemon lab.
The event scene in Pokemon Pearl where the player meets Professor Oak on route 224 is part of a Nintendo-sponsored special event in order to obtain the legendary Pokemon, Shaymin. The player must be involved in the special event to obtain the key item called Oak's Letter, and afterwards Professor Oak will appear on route 224.

He is in Sandgem town in the Professor's lab.

truthfully u don't need an AR. There is a video on tweaking for darkrai on youtube. The islands are right next to each other, so just customize the tweakHappy Tweakinghttp://wiki.answers.com/Q/User:75.18.186.133!This is Katy_90_123's response:Here is a better and more specific answer. Sorry there is no action replay. If you completed the Sinnoh PokeDexand received the National PokeDex, Professor Rowan or Oak should have announced that Route 221 is unlocked. Go inside PalPark by the Counter Desk and save. Next (You can only do this if you have platnium) put in your Pokemon Platnium game. Migrate your Pokemon from Pearl or Diamond in Platnium. Then transfer some of your Platnium Pokemon to Pearl's or diamond's in PalPark. Put in your Diamond or Pearl game again and enter a Catching Show in PalPark. It takes a huge amount of time to find Shaymin but hope this improved the answer above. :)
You can find professor Oak, in Pallet town for older Pokemon games. For most of the Pokemon games there isn't any professor oak you can only find professor Rowan in Samage town.Usually in some places in the Pokemon world, you can find Dawn in front of one of the places were one of the professors work.
by finishing the first pokedex and then professor oak give you the national pokedex
you just have to finish collecting data on your pokedex then get an upgrade from professor Oak
