Originally used for testing scripts, Fire Red 251 eventually became a hack that tries to be as low-key as possible with it’s modifications, while improving the game for the better.

This hack aims to do the following:

• Take away various attempts to make the game’s normal Trainer battles easier.
• Fix out-of-place Pokemon in Gym Leaders’ teams.
• Slightly update later Leaders to a higher difficulty, hopefully to match the other Pokemon games released at this time. Later important battles are rather in need of an improvement when you look at them.
• Restore excluded items and balls in a way that doesn’t hinder the original gameplay.
• Fix glitches present in the original game.
• Restore gambling references completely. There are extra patches included that restore other well-known localization changes.
• General ease-of-life improvements such as deleted intros before Professor Oak or upon continuing, a new “stone” for trade evolutions, deletion of tutorial text, and running indoors.
• Make all the first 251 Pokemon available (plus Azurill and Wynaut), bringing FireRed’s roster as it should had it been a single game.
• Improved Pokemon Sprites.
• De-capitalization of text.
• A variety of optional patches. Play the game with new Hidden Power mechanics, run from the very start, or open up the Regional Dex to fully include the evolutions blocked from you.
