# SUPER3

Open-source Sega Model 3 emulator for Android

Available now

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/<package>/files/super3/Saves/`
- Optional sync/export: May use Android’s Storage Access Framework; if enabled, the app only accesses folder(s) you explicitly choose.

## Legal / Google Play Policy Notes

- No games included: SUPER3 does not ship with ROMs or game data, and it is not intended to facilitate piracy.
- You must own the games: Only use ROMs you are legally permitted to use in your region.
- Trademarks: “SEGA” and all associated game names, trademarks, and copyrighted works are the property of their respective owners.
- Not affiliated: This project is not affiliated with or endorsed by SEGA or any arcade hardware manufacturer.

## Privacy

- SUPER3 can run offline for emulation, but Flyer view may download artwork from GitHub.
- The app stores emulator settings, save states, and screenshots locally on your device.
- If you opt into selecting a user folder for syncing/export, access is limited to the folder you select via the system file picker.
