Pokemon Red - NC Revision ROM

Pokemon Red – NC Revision is a Game Boy ROM Hack by Ninjacat25 based on Pokemon Red. It was last updated on March 18, 2026.

Description

Features

Graphical tweaks

• Every trainer battle sprite (Including two completely ones, and two redesigned ones outside of those featured in the original game)
• Many, if not all overworld sprites
• Some of the Pokémon’s front sprites (Including the full starter Pokémon lines, Pikachu, Raichu, Oddish, Machop, Golem, Ekans, Dratini, Dragonair, Dragonite, Jigglypuff, Wigglytuff, Pidgey, the PureRGB Tower Catacombs Pokémon, and perhaps more)
• Many tilesets
• Title screen, trainer card, and back sprites for the player character
• New logos for the title screen, varying between the Red, Green, and Blue versions, using the Pokémon Gold and Silver logos as a base
• I believe some of the Gym Leader overworld sprites might be edited versions of Gen 2 ones?

Other tweaks

• Restored the towns’ Japanese names
• Restored/retranslated most human characters’ Japanese names
• Changes the option to throw rocks at Safari Zone Pokémon to simply going near them, though the option will be mechanically identical
• Some minor text changes to ensure that the game still feels like it’s from the ’90s
• Some text references to other videogames that I’m fond of
• The player is slightly more polite to Copycat
• The Great Ball has been renamed to Super Ball, the Ultra Ball has been renamed to Hyper Ball, and PureRGB’s Hyper Ball has been renamed to Mega Ball
• A hiker is high on mushrooms, like in the Japanese version
• Translated the bird wordplay in Erik/Koji and Sara/Atsuko’s Japanese dialogue into English (In the Japanese version, Atsuko says “Pokémon tori”, meaning “obtain Pokémon”, while Koji says “tori Pokémon”, meaning “bird Pokémon”. This wordplay was omitted in the English version, as the joke was specifically reliant on the Japanese language. My attempt to translate the joke was making Sara/Atsuko say “I wanna win Pokémon here”, with Erik/Koji mishearing it as “I wanna winged Pokemon here”. Maybe there’s a better way to translate the joke, but hopefully my attempt works well enough)
• Seafoam Islands/Twins Island is now referred to as a single island, like in the Japanese version
• One of the bikers now says “Think you’re sneaky, pipsqueak?!” instead of “Come out and play, little mouse!” in order to make him sound less creepy
• Some of Sabrina/Natsume’s dialogue in Bill’s/Masaki’s Garden has been changed (PureRGB adds an area called “Bill’s Garden” to the game)
• Changes to the protagonist’s dad’s dialogue and appearance, based on my own father (PureRGB adds the protagonist’s dad as an interactable character)
• Prof.Oak/Dr.Okido now talks to you on the phone about Pokémon Box storage, as opposed to the Pokémon Snap reference seen in PureRGB
• The upper classroom featured in PureRGB is no longer referred to as “Detention”, as Japanese schools might not have detention
