Back in 1999, two games were born. These games were designed for the Game Boy/ Game Boy Color, and have gone down in the history books as two of the greatest games ever made. These games are known as: Pokemon Gold and Silver Versions.
11 years after the original release of these games, their remakes were born: Pokemon HeartGold and SoulSilver versions. Gamers were practically begging for these games since Pokemon FireRed and LeafGreen (Remakes of Pokemon Red and Blue (Green in japan)).
The pros about these games? No more pesky save batteries to go bad; flash memory, baby! The bad? It took 6 years until Nintendo finally listened up and made them. But in the meantime we were playing Pokemon ShinyGold version (A bootleg of Pokemon Gold verion based off of Pokemon FireRed's engine). HA! Eat that Nintendo.
