Play Gameboy Games Online — Free GB/GBC ROM Player
Gameboy ROM Player lets you play Gameboy games online for free — Game Boy and Game Boy Color ROMs run right in your browser, with no upload and no account. You supply your own .gb or .gbc game file (or a .zip containing one); it boots instantly with sound, on-screen touch controls, keyboard support, and battery .sav saves. Everything runs on your device — this is a Gameboy emulator online with nothing uploaded.
Choose a .gb, .gbc, or .zip ROM above and it plays instantly. Use the on-screen D-pad and A / B / Start / Select buttons on a phone, or the keyboard on desktop. Everything runs in your browser — nothing is uploaded.

Open the free Gameboy ROM Player →What you need to play
You need one thing: your own Game Boy or Game Boy Color ROM file — the .gb or
.gbc game dump you already have on your device. This tool is a player, not a game library:
it does not host or distribute any games, so nothing to play is included. If your ROM came as
a .zip, you can load the zip directly and the game inside is unpacked for you. Files up to 8 MB
are supported, which covers every official Game Boy and Game Boy Color cartridge.
Capsule Tools does not provide, host, or link to game ROMs, and can't help you find them. You're responsible for using only game files you're legally entitled to — cartridges you own and have dumped yourself, or free homebrew and public-domain games. This is a general-purpose player for your own files.
How to play Gameboy games in your browser
Because the emulator runs on WebAssembly entirely inside your browser tab, you can play Gameboy games in your browser on any modern device with no install and no upload:
- Open capsuletools.app/gameboy-rom-player/
- Tap Choose ROM file (or drag a file onto the box) and pick your
.gb,.gbc, or.zip - The game boots immediately — play with the on-screen controls on a phone, or the keyboard on desktop
- Use the settings cog to toggle sound, switch between colour and the classic Game Boy green, change the pixel look, or back up your save
Controls — keyboard and touch
On a phone or tablet you get an on-screen D-pad and A / B / Start / Select buttons that support multi-touch, so you can hold a direction and press a button at once. On desktop, use the keyboard:
- Arrows / WASD — D-pad
- Z — B
- X — A
- Enter — Start
- Shift — Select
A Reset button restarts the game, and Pause freezes it without losing your place.
Saving your progress
Games with a battery save — like Pokémon or The Legend of Zelda — save the same way they did on real hardware.
Your .sav battery data is written to your browser's storage automatically
whenever you leave or switch away from the tab, so your progress is waiting when you return. In Settings you can
Export that save as a standard .sav file to back it up or move it to another device
or emulator, and Import a .sav to bring an existing save in. Games that use a
password system instead of a battery have no .sav to export.
Is it safe and private?
Yes. There are no ads, no account, and no server. Your ROM and your saves are read and run inside your own browser and never leave your device — because nothing is uploaded, no third party ever receives your files. You can even add the player to your home screen and launch it like an installed app.
Frequently asked questions
Can you play Gameboy games on your phone or iPhone?
Yes. Open the Gameboy ROM Player in your phone's browser — Safari on iPhone and iPad, Chrome on Android —
tap Choose ROM file, pick your .gb or .gbc from the Files app, and it plays instantly
with on-screen touch controls. There is no app to install and nothing is uploaded, so it works the same on any
modern phone.
Do I need to download or install anything?
No. This is a Gameboy emulator with no download — it runs entirely in your browser tab using WebAssembly. You
only supply your own game file (a .gb, .gbc, or a .zip containing one).
You can optionally add it to your home screen to launch it like an app, but there is no install and no account.
Is this Gameboy emulator safe to use?
It is safe and private. There are no ads, no account, and no server: your ROM and save files are read and run inside your own browser and never leave your device. Because nothing is uploaded, there is no third party that ever receives your files.
What are the keyboard controls?
On desktop, the arrow keys (or W, A, S, D) work the D-pad, Z is B and X is A, Enter is Start, and Shift is Select. On a phone or tablet, an on-screen D-pad and A / B / Start / Select buttons appear below the screen and support multi-touch, so you can hold a direction and press a button at the same time.
How do Gameboy .sav save files work (export, import, and auto-save)?
For games with a battery save (like Pokémon or Zelda), your progress is written to your browser's storage
automatically whenever you leave or switch away from the tab, so it's there when you come back. In Settings you can
Export your progress as a standard .sav file to back it up or move it to another device, and Import
a .sav to restore it. Games that use passwords instead of saves have no .sav to export.
Can I play Gameboy games on a Chromebook?
Yes. The player runs in Chrome on a Chromebook with no install and no extension — just open the page and choose your ROM file. You can use the keyboard controls or the on-screen buttons, and it works even on managed school Chromebooks since nothing needs to be installed.
What do I do if there is no sound?
Browsers block audio until you interact with the page, so sound starts once you load a ROM and tap a control. If it's still silent, open Settings and check that Sound is On, make sure your device isn't muted, and note that some games simply have quiet or minimal audio.
Why is the sound delayed or out of sync?
In-browser audio timing can occasionally drift, so the sound falls slightly behind the action. Tap Reset to resync the sound and picture — note that Reset restarts the current game, though any battery save is kept. This is a normal quirk of browser audio and can happen on any device.
Do all Game Boy and Game Boy Color games work?
Most do, but not every single one. The player runs a lightweight in-browser emulator, and while the large majority of Game Boy and Game Boy Color games play well, a few titles — especially graphically demanding Game Boy Color games — may show visual glitches or not run perfectly. That's a limitation of the emulator itself, not your ROM or your device. If a game looks wrong, it's worth a Reset, but some games simply push beyond what an in-browser emulator handles cleanly.
Will it remember my game when I come back?
Yes. Your current game and your exact place in it are saved on your device, so if you switch apps, lock your phone, or even close the tab, reopening the player drops you back where you left off — just tap Resume. It's all stored locally and never uploaded. To clear it and start fresh with a different game, tap Eject.
