THE ONE-PROMPT INSTALL
Claude Code installed 3D Pokemon in one prompt.
The game in that reel is real Pokemon Yellow, running as a 3D voxel world on my Mac. A fan project rebuilt the Game Boy engine, a mod redraws the overworld as a diorama, and Claude Code set all of it up from one pasted prompt. That prompt is below.

WHAT'S GOING ON
- →gen1recomp is a fan rebuild of the Gen 1 engine. It runs Pokemon Yellow natively on Mac, Windows, Linux, even Switch and iPhone, from your own cartridge dump.
- →The 3D look comes from the DRAMATIC_SHAPE mod. It draws the overworld as a voxel diorama and adds 3D battles plus an experimental first person mode.
- →Claude Code does the install. It downloads the engine, checks the file hashes against the release, and puts the mod where the game looks for it. Your job is pasting one prompt.
“Pokemon Yellow in third person feels way too cool.”

THE SETUP — 5 STEPS
02
Paste this prompt
Open a terminal, type claude, paste this. It downloads gen1recomp, verifies the checksums, and installs the voxel mod where the game expects it.
Set up Pokemon Yellow as a 3D voxel game on my machine. Do all of it for me: 1. Make a folder called pokemon3d in my home directory and work inside it. 2. Go to https://github.com/bryanthaboi/gen1recomp/releases and download the newest build for my OS (on Mac that's gen1recomp-<version>-macos.zip) plus sha256sums.txt from the same release. Verify the checksum before unzipping. 3. Unzip it. On Mac, if the app gets quarantined, clear it with: xattr -dr com.apple.quarantine gen1recomp.app 4. Download the newest release zip from https://github.com/DramaticShape/DramaticShapeVoxelMod/releases and extract it into the game's mods folder, so the mod files live at <save directory>/pokemon-love2d/mods/DRAMATIC_SHAPE. On Mac that's ~/Library/Application Support/pokemon-love2d/mods/DRAMATIC_SHAPE. Create the folders if they don't exist yet. That mod is what draws the overworld as a 3D diorama. 5. Do NOT download a ROM. I own a Pokemon Yellow cartridge and I'll provide my own legally dumped .gbc file. Just tell me where to put it. 6. Open the app. I'll drag my ROM onto the launcher window and it builds its game cache from my file. 7. Once it runs, tell me exactly where the VOXEL settings live in the options menu so I can turn on 3D mode and first person myself.
03
Add your ROM
The project ships no game files. You need your own legally dumped Pokemon Yellow .gbc from a cartridge you own. When the launcher opens, drag your ROM onto the window and it builds its cache from your file.
04
Flip the voxel settings
In the game, open options and find the VOXEL section. Turn voxel mode on, and try first person while you're in there. Q and E zoom on keyboard, the sticks zoom on a gamepad.
05
Not on a Mac?
Same release page carries Windows, Linux, Switch, Android, even iPhone builds. Tell Claude Code what machine you're on and it grabs that zip instead. The mod folder moves with the game's save directory, and the prompt already tells it to find the right one.
