For me Pokemon Emerald. I can't really explain why though. i have both games and emerald just seems better. Oh and the league is very tough in FR
emerald due to its extra content like Pokemon contests and rematching gym leaders plus the battle frontier is included though firered has things like the islands and better elite four so im going with emerald.
I believe firered leafgreen is better then ruby Sapphire because the graphics are better and you are able to play the classic original Pokemon with the first 150. The challeneges and towns are great and the Pokemon are original unlike the newer ones who seem like they were rushed.
emerald no doubt
I cant tell you all the differences but I do recomend Fire Red version
I personally like Emerald better, but Pearl has better graphics.
Emerald..But they are kinda the same
It depends. Diamond has better graphics, but Emerald has a better plot line and in my opinion is better.
ACTION REPLAY!!! on the website they have codes for every single pokemon. game shark probably does too, but ar is easy
Pokemon fire red is better.
Pokemon from white are WAY better than pokemon from emerald.
No emerald is better than Sapphire
Emerald by far
