Even though ultra-rare shiny Pokemon were only properly introduced in Pokemon Gold and Silver, that doesn't mean that they don't exist in Red, Blue, and Yellow, and one mod will make sure you'll never miss any ever again.
Shiny Pokemon are some of the most highly sought-after finds in the entire RPG series. While the odds of finding these alternate color palette Pokemon vary depending on which game you're playing, they can be as low as 1/8192. You might think that the odds would be zero in Red, Blue, and Yellow – after all, you'll never see any sparkles in those games – but that's not quite the case. When transferred to Pokemon Gold, Silver, and Crystal, many Pokemon caught in the original games can actually show up as shiny due to the way that 'shininess' is determined in the second generation.
