MSX JoyMega Bluetooth Wireless Module

What is it?

The MSX JoyMega Bluetooth Wireless Module is a Bluetooth controller receiver for MSX computers, based on the famous open source project BlueRetro. It is compatible with almost all Bluetooth controllers and supports fully customizable button mapping — no modifications to your MSX required.

Turn your MSX into a wireless game console like the PS4. Say goodbye to hard-to-find original MSX controllers or wired JoyMega adapters forever.

Why Was It Made?

Original MSX controllers are increasingly rare and expensive. Wired JoyMega adapters, while functional, still tether you to your console. This module solves both problems: plug it into your MSX's joystick port and use any modern Bluetooth controller wirelessly — instantly.

It supports JoyMega compatibility mode, meaning full 6-button Mega Drive mapping plus Start and Mode buttons — exceeding what 8BitDo adapters offer for MSX.
