Pokemon Yellow 97+ ROM

Pokemon Yellow 97+ is a Gameboy ROM Hack by Cremason based on Pokemon Yellow. It was last updated on May 12, 2025.

Description

Welcome to Pokémon 97+. The “97” comes from those cool Spaceworld ’97 backsprites I’ve added, and the “+” is because this is my take on a “vanilla-plus” experience. I didn’t want to stray too far from what makes Yellow special—it’s still gotta feel like the game we all know and love, just with some extra flavor.

Features

• Tons of manga-inspired graphic tweaks and those sweet Spaceworld ’97 backsprites.
• Fixed some Pokémon palettes—like Eevee’s now brown instead of green (what was up with that?).
• You can pick a girl trainer based on Green from the manga.
• Blue and Green’s sprites got a glow-up, and Red’s front and backsprites got a little love too.
• New Oak frontsprite, plus a post-Hall of Fame battle with a manga-inspired team.
• Mew’s hanging out in Pokémon Mansion now.
• Gym leaders got slight team tweaks (manga vibes), including an Armored Mewtwo on Giovanni’s squad,
• Team Rocket’s roster’s less repetitive—swapped some dupes for Tauros and Pinsir.
• Jessie and James pick up a Lickitung late-game.
• Pikachu can learn Surf and evolve into Raichu now—oh, and Raichu can follow you too!
• Updated Blue sprite for the Pokémon Tower battle, with tweaked dialogue.
• Crystal Onix and a new Brock fight in “Crystal Cavern.”
• Second battles with Brock and Misty! Brock’s in Crystal Cavern, and Misty’s date gets crashed at Saffron Diner (Gold/Silver style—her Starmie’s ready for revenge)
• Pink Butterfree obtainable through trading on the ss anne and then trading back in Saffron Diner.
• Charizard, Blastoise, Venusaur, And all FInal Evolutions will now follow you!
• Mewtwo Side Event! – starts with dragonite delivering an invite after Fuchsia Gym and leading you to find a missing nurse joy and find new island. (This is a WIP because i have yet to connect the invite to cinnabar island but its cool none the less)
• NEW Evening Mechanic! when you talk to the old man In his isolated house in cerulean city you can turn the routes to sunset and really look for those rare pokemon found only in blue and red versions.

How’s This Different from the Old Version?

This used to be called Pokémon Yellow 98, and I also had a version tied to Smithplays’ Legacy hack. That was more about blending updated graphics with a legacy feel, but 97+ is my own thing—a tighter, closer-to-vanilla take. It’s got cut content like Mew and the Oak fight, plus small gym team changes that fit the manga. It’s a different vibe—familiar but fresh.
