# SUPER3
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` fork (ARM branch).

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 by the title).

- **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.
These settings are written to `.../Android/data/<package>/files/super3/Config/Supermodel.ini` (`XResolution`, `YResolution`, `WideScreen`, `WideBackground`, `New3DAccurate`).
## Files & Storage
- Save states and thumbnails are stored under the app's user data directory in `Saves/` (for example: `.../Android/data/<package>/files/super3/Saves/`).
- The app may offer an optional "sync"/export workflow using Android's Storage Access Framework. If enabled, the app only accesses the folder(s) you explicitly choose.

## Flyers
- Flyers are downloaded on-demand (when you switch to Flyer view) from `https://github.com/izzy2lost/Model3flyers`.
- They are stored in `.../Android/data/<package>/files/super3/Flyers/` as `<game>_front.png` and `<game>_back.png`.
- You can replace or add files in that folder to customize artwork.

# Super3 Android (Scaffold)
This folder is a **starter Android Studio project** for the Super3 ARM codebase.
What works right now:
- Builds an Android app (API 36) + a native shared library (`libsuper3.so`) using **NDK r29**.
- App loads the native library and shows a text string from JNI.
What still needs real porting work:
- The emulator uses the SDL OSD/renderer on desktop (`Src/OSD/SDL/Main.cpp`). Android needs an Android OSD layer:
- Option A: bring in **SDL2 for Android** and adapt the SDL OSD to use SDL2 Android activity.
- Option B: port the OSD to **GameActivity/NativeActivity** and EGL/OpenGL/Vulkan as needed.
## Build requirements
- Android Studio (Otter era or newer)
- SDK Platform: API 36
- NDK (Side by side): `29.0.14206865`
## Project layout
- `android/app/` - Kotlin app + CMake build
- `android/app/src/main/cpp/CMakeLists.txt` - builds most of `Src/` into a shared library (excludes desktop mains/tools)
## Wiring SDL2 (recommended next step)
1. Add SDL2 source under `android/third_party/SDL` (or as a git submodule).
2. In `android/app/src/main/cpp/CMakeLists.txt`, uncomment the `add_subdirectory()` example and link SDL2.
3. Decide how you want to expose your emulator entry point on Android (JNI, `android_main`, or SDLActivity).
