http://www.Pokemon.com - There is no one specific website for Pokemon FireRed and Pokemon LeafGreen, but the official site will have all of the info you need to know on the two games. You can also search Google (Bing, Yahoo!, etc.) for specific results on other websites' pages just for Pokemon FireRed and Pokemon LeafGreen.
for me the best site is Pokemon lake but if that gets boring then try Pokemon indigo or Pokemon volcano
you could download the ROM from romsite.net and get the VBA emulator from any emulator site then go to the game shark codes site and find firered or firered/leafgreen and use the cheats to do that. either than that, its impossible
well firered and leafgreen have SOME different Pokemon so you can get those Pokemon from leafgreen. so here is the site that list the different Pokemon. just scroll down to the chart... http://bulbapedia.bulbagarden.net/wiki/Pok%C3%A9mon_FireRed_and_LeafGreen_Versions
in my opinion, the best site for Pokemon is marriland.Pokemon.com
the best site to download pokemon black and white is WWW.DSIROM.COM
Go tohttp://sites.google.com/site/thewaterpath/its on island seven you will have to have the rainbow pass to get there.
