Sega CD/MD/GG Emulator-Trilogy

Sega CD/MD/GG Emulator lets you play your own Sega CD, Sega Mega Drive/Genesis, and Game Gear ROMs — three classic Sega systems in one app, offline, with a real cloud-save system — no subscriptions, no ads, one-time purchase.

🎮 YOUR OWN ROM LIBRARY
Point at a folder on your device and add your Sega CD, Mega Drive, or Game Gear ROMs into a clean, organized library. Rename games, set custom cover art, and search your collection — everything stays neatly managed, not just a messy folder of files. Added a game under the wrong system by mistake? Instantly switch it between Sega CD, Mega Drive, and Game Gear right from your library, no need to delete and re-add. Select multiple games at once to bulk re-tag or bulk delete — handy if you're importing a large collection.

💾 REAL SAVE STATES & SAVE DATA
Unlike simple "upload and play" emulators, your saves are real and persistent — save state anywhere, anytime, and pick up exactly where you left off. Log in (Google, Facebook, Discord, or Microsoft) to sync your saves to the cloud and never lose progress, even on a new device.

🕹️ CUSTOMIZABLE CONTROLLER & HARDWARE SUPPORT
Virtual Gamepad: Move, resize, and rearrange every on-screen button to fit your hands — drag any button to reposition it, pinch to scale, and build a layout tailored to your playstyle.

External Gamepad Support: Plug and play with your favorite Bluetooth or USB controllers (Xbox, PlayStation, 8BitDo, and more) with full button remapping.

Built-in Turbo / Auto-Fire: Easily enable Turbo buttons in the settings for effortless rapid firing during intense action segments.

🎮 3 FREE GAMES INCLUDED
No ROM yet? No problem — Sega CD/MD/GG Emulator ships with 3 free, legally licensed Mega Drive homebrew games (Gem Rush, Miniplanets, Dragon's Castle) so you can start playing the moment you install, while you build out your own Sega CD and Game Gear collection.

🚫 NO ADS, EVER
This is a one-time paid app — no banner ads, no interstitials, no "watch a video to continue." Just a clean, focused, all-in-one Sega emulator.

🌐 EN / VI SUPPORT
Full English and Vietnamese language support, switchable anytime in-app.

⚠️ Please note: this app is an emulator only. It does not include or distribute any copyrighted games. You are responsible for only using ROM files you legally own.

Made with care by KhoGameHub Studio — also creators of KhoGameHub Retro Emulator, an online library of 13,000+ games across 18+ consoles, playable instantly with no ROM management needed.
