G1R Deluxe / Gen1Recomp (Pokémon Red and Blue PC port)

Pokémon Red and Blue are Game Boy games from the 1990s by Game Freak, and Nintendo has never released them on PC. bryanthaboi created the gen1recomp repository on 18 July 2026 and published v0.1.0 the same day. It first drew attention for a 3D voxel look: Kotaku covered it on 29 July 2026 as a mod that turns Kanto into a diorama, and DSOGaming followed on 3 August. The README now calls it G1R Deluxe, and the repository had almost 4,000 GitHub stars on 21 October 2026.

What it is

• A recreation, not a recompilation: the README says the engine and map behaviour are hand-written Lua, ported from the pret disassemblies. It does not emulate the Game Boy, translate the original assembly or download a disassembly.
• Data from your own ROM: on first launch it decodes the game data, graphics and audio programs from a ROM you supply, verifies it, and then drops it from memory. Later launches use a private generated cache. Music, sound effects and cries are synthesised as you play.
• More than Red and Blue: Yellow is supported too, and the README lists Gold, Silver, Crystal, FireRed, LeafGreen, Ruby, Sapphire and Emerald. It says Gen 2 support is still under construction and the Game Boy Advance games are in beta. Each game you import gets its own tab in the launcher.
• Made by people, mostly: the project’s AI disclosure says a few contributor commits used AI tools and were reviewed by humans, and that AI was not used to make decisions or create the project.

On this site it sits with ports like Ship of Harkinian for Ocarina of Time, which also rebuild a game from community reverse-engineering and need your own copy.

Current status

Features from the README:

• keyboard and controller controls, all rebindable;
• zoom, colour modes, tilt for a free-roam 3D-style overworld, shader effects and adjustable game speed;
• rulesets that keep the original Gen 1 quirks or clean them up;
• online lobby, battles, tournaments and trading;
• a mod manager (F10), with the voxel look among the community mods;
• performance tiers for weak hardware that change only the presentation, never the game logic.

We didn’t play the game through ourselves. The README asks for bug reports on anything that does not match the original games, such as wrong warps or battle maths.

What you need

• A ROM of your own US English Pokémon Red, Blue or Yellow. Only the exact revisions in the README’s SHA-1 table are accepted, and other regions or hacks are rejected. The same rule applies to the other supported games. We don’t explain how to obtain or copy game data.
• A supported device: a PC, Mac or Linux machine, an Android phone, or one of the other platforms in each release. Some, such as Switch, PS4 and Xbox, have their own setup notes in the repository.

How to install

From the official README, at a high level: download the build for your platform from the latest release on GitHub, launch it, and choose your ROM file (or drop it onto the window). Import takes a few seconds and the game starts by itself. Repeat for any other supported game you own.

Windows Defender sometimes flags the Windows build with a generic detection. The README calls this a known false positive, caused by the unsigned LÖVE runtime with the game archive attached, and every release publishes sha256sums.txt so you can check your download.

Other Pokémon fan projects

• Gen2Recomped by UNDERdecoded: a fork of Gen1Recomp that started with Gold, Silver and Crystal and now lists later generations in alpha or pre-alpha. It is on our recompiled games list.
• Pokémon Battle Advanced: a fan remake of the start of FireRed in 3D, playable in the browser.
• Daily Red: a daily battle against Red in the browser, Wordle-style.
• PokéMerge: a Pokémon roguelike with a merge mechanic, in the browser.

Those three are new fan games rather than ports, and none needs your own ROM.

For the other main games, from Ruby to HeartGold, see Pokémon decompilations: which ones are complete and which have a PC port (so far, only Red and Blue and Emerald).

Is it legal and safe?

• G1R Deluxe is an unofficial fan project. The README says the packaged app contains no ROM and no game data; everything game-specific is decoded from the ROM you provide.
• Use only a ROM of a game you own.
• Do not use gen1recomp[.]com. The README says that site is not run by the project, impersonates it and serves adware. The official sources are the GitHub repository, its releases page, the Discord and gen1re.com.

More handheld classics on PC: Final Fantasy Tactics Advance, The Minish Cap. Every project by console is on our recompiled games list.
