EmuMD XL is a free Android emulator developed by Pentawire that allows you to play Megadrive/Genesis games on your mobile device. The app delivers high-quality graphics and sound emulation, making the gaming experience on your phone as good as it was on the original console.

The app offers an easy-to-use interface for finding ROMs, with a deep scan feature that enables you to place your ROMs in your device's "Download" folder. EmuMD XL supports various file types, including "bin," "gen," "smd," "md," "sgd," and ".zip" files.

The on-screen controllers are customizable and emulate various device types, such as three-button joypads, six-button joypads, and menacer. The app also supports hardware peripherals like gamepads, joysticks, and keyboards. You can even swap controllers for turn-based two-player games.

EmuMD XL also allows you to save and load game states, so you can pick up where you left off. It's worth noting that no game ROMs are included with the app, and the screenshots are from various open-source/free games by Retrosouls.
