About this game

A highly accurate native Sega Master System and Sega Game Gear emulator. This is my first Android app and the culmination of a project to port my C-based emulator from the PC platform. The feature set includes:

* Open source - repo at https://github.com/PhilPotter/MasterEmu
* No ads or in-app purchases.
* Pro Action Replay and Game Genie cheat code support.
* Android TV support.
* Android 4.4 to 13.0 support.
* Physical controller support, for menus as well as in-game emulation.
* Controller button remapping support.
* European/US or Japanese console selection.
* ZIP file support.
* Near perfect Master System and Game Gear emulation, at excellent speed.
* Saving and loading of emulation state from any point.
* Save state import/export and management.
* Auto-handling of SRAM saves, for ROMs that use it (like Phantasy Star).
* Auto-rotation, as well as lockable screen orientation.
* Adjustable touchscreen button size, as well as dynamic button labelling depending on console type.
* Ability to optionally disable touch overlay if using controller.
* DPI-independent button size.
* File browser which can load ROMs off internal or external storage, in '.sms' or '.gg' format, and also with ZIP files.
* Widescreen (default) and 4:3 (optional) in horizontal mode.

Please note that ROMs must be legally obtained by the end-user. Please don't ask me where to get them, although constructive feedback on the emulator itself is welcome, including feature requests. I am a lone programmer and am not affiliated with Sega in any way. I hope you enjoy what I've created with MasterEmu!

Ratings and reviews

I liked this emulator. Really. Clean and simple, direct to the point, no adds. It would've been perfect if not for the fact that anytime that my phone would switch in or out of battery saving mode, the app would simply freeze, making me lose loads of progress (I'm using it on a Moto G7 plus, btw). Should it get fixed, I would gladly give it 5 stars, as it deserves it. Another thing, but that's just a mild annoyance, is that there's no way to adjust the button's size/transparency.

Fantastic Emulator App. It is a clean interface, has no nonsense in it, is completely free with absolutely no advertising. This will run full screen with Bluetooth controller support (or USB) and works very well. I tried Asterix and Oblix from Sega Master System 1 and it was so much like the original that you could not tell, apart from better controls and the ability to save your game ETC! Give it a try. I fully recommend it.

I really like this app and I can have fun playing Sonic 1 and Triple Trouble on it despite the somewhat awkward controls and lack of functions, but I will still give it 4 stars since it doesn't have any ads nor you have to pay for it, so I get the creator just does it for fun, not much I can say apart from that, it just works well and a SMS/GG emulator for mobile is welcome to me, since both consoles are not very well known

What's new

* Introduced controller remapping, long time coming!
* Rewrote input handling for controllers - it is now entirely native code, with the Java workarounds removed.
* Integrated Storage Access Framework.
* Updated SDL version and other build dependencies for both the Java and C codebases.
* Expanded permissions checks for Bluetooth controllers to work more reliably.
* Adjusted colour of buttons.
* Various bug fixes/modernisations all over the place.
