What GB-EMU is

GB-EMU is an emulator packaged as an application for Samsung Tizen TVs, where it runs Game Boy and Game Boy Color games directly on the TV rather than streaming them. It is a work in progress, and its CPU instruction set is incomplete; the project describes its purpose as educational and for testing. Games load from .gb and .gbc files at the top level of a USB drive or can be downloaded over Wi-Fi from a PC on the same network. Downloaded games remain on the TV for offline play after the PC server stops. Each game has one save slot, stored in private TV storage across restarts and app updates. Samsung remote controls are mapped, and standard gamepads work through the Gamepad API. The remote's B, Select, and Start inputs register only as taps, so a Bluetooth gamepad is needed for games requiring a held B input. A desktop-browser build supports loading files and keyboard play. TV installation requires Developer Mode and the Tizen widget installation process. The project is free under the MIT License and comes without warranty.

Who it suits

GB-EMU suits people exploring Game Boy architecture or low-level emulation for educational and testing purposes. It may also interest hobbyists who want to run homebrew emulation on a Samsung Tizen TV.

What it does well

Runs directly on Samsung Tizen TVs
Loads .gb and .gbc files from USB or Wi-Fi
Downloaded games remain available offline
One save slot per game persists across restarts
Supports standard gamepads and desktop-browser play

What to know first

Work in progress with an incomplete CPU instruction set
Remote B, Select, and Start inputs are tap-only
Users must provide legally obtained ROMs
TV installation requires Developer Mode

Limits

The project is still under development, and its CPU instruction set is incomplete. USB ROM discovery only checks the top level of each drive, and each game provides one save-state slot.

Getting started

Open the GB-EMU_Tizen project website
Enable Developer Mode on the Samsung TV
Install the signed Tizen .wgt package using Apps2Samsung
Load legally obtained .gb or .gbc ROMs from the top level of a USB drive
Alternatively download ROMs over Wi-Fi from a PC on the same network
Use the Samsung remote or connect a standard gamepad

Verdict

GB-EMU offers direct-on-TV Game Boy emulation alongside a desktop-browser option, but its incomplete CPU support makes the project an in-progress tool. Check controller input requirements and provide your own legally obtained ROMs.
