SUPER3 is an open-source Sega Model 3 emulator for Android. It is based on the Supermodel emulator by trzy, with additional work derived from the model3emu-code-sinden (ARM) fork.

No games are included. This app does not include any games, ROMs, BIOS files, or copyrighted game content. You must supply your own legally obtained game ROMs.

Features:
Sega Model 3 emulation (compatibility varies by title/device)
On-screen touch controls (Service/Test/Coin/Start and game-specific controls)
Virtual on-screen steering wheel for driving games (when supported)
Save states (10 slots) with automatic screenshot thumbnails and tap-to-preview
In-game pause/resume button
Game flyers (front/back) in the launcher list
Video settings (Resolution & Widescreen)
Video Settings
From the main game list, open the side menu (toolbar “menu” icon) and look under Video.

Resolution: Native (496x384) and integer scale options (2x through 8x). Higher values look sharper but can reduce performance.
Match device resolution: Sets the internal resolution to your device’s exact pixel resolution (landscape). This also enables Widescreen and Wide background.
Widescreen: Expands the horizontal field of view (Supermodel -wide-screen). At very wide aspect ratios some games may cull objects at the edges.
Wide background: Stretches the 2D background layers when using widescreen (Supermodel -wide-bg).
Enhanced Real3D (experimental): Enables more desktop-like Real3D rendering (multi-pass transparency compositing + scroll fog). This can improve visuals in some games/areas, but may reduce performance on lower-end devices..

Files & Storage
Save states & thumbnails: Stored under .../Android/data//files/super3/Saves/
Optional sync/export: May use Android’s Storage Access Framework; if enabled, the app only accesses folder(s) you explicitly choose.
Flyers:
Flyers are downloaded on-demand (when you switch to Flyer view) from https://github.com/izzy2lost/Model3flyers.
